Abstract
An efficient and highly regioselective C6-phosphorylation protocol for pyrrolo[2,3-d]pyrimidine (7-DAP) derivatives with various H-phosphine oxides induced by visible light at room temperature is described for the first time. This protocol has been successfully achieved by the combination of Na2-eosin Y as a photocatalyst and LPO as an oxidant under transition metal- and additive-free conditions. The broad substrate scope, good functional group tolerance, excellent regioselectivity, and air tolerant conditions make this process favorable for the functional modification of pyrrolo[2,3-d]pyrimidine scaffold and enrich the phosphorylated 7-DAP compounds for further biological evaluation.

Abstract
A novel and efficient method for the synthesis of aryl phosphonates from aryl halides and trialkylphosphites via EDA complex-based photochemistry has been developed. It is demonstrated that aryl radicals, generated from the photoexcitation of the EDA complex formed by aryl halide and potassium thioacetate, could be intercepted with trialkylphosphite to produce the corresponding aryl phosphonates in moderate to good yields. It should be noted that the reaction is performed at room temperature in the absence of any transition metal catalyst, oxidant and photocatalyst, exhibiting high efficiency, high selectivity, and operational simplicity.

Abstract
A literature survey showed that different derivatives with the 9-phenyl-9H-carbazole or the dihydroindoline scaffold may be of biological activity including cytotoxic effect. Driven by this experience, P-functionalized derivatives of these N-heterocycles were synthesized. Three N-heterocycles, 9-(4-bromophenyl)-9H-carbazole, 3-bromo-9-phenyl-9H-carbazole and 1-(5-bromoindolin-1-yl)ethan-1-one, were coupled with dialkyl phosphites and diarylphosphine oxides using Pd(OAc)2 (10 %) as the catalyst precursor and triethylamine as the base in ethanol under microwave irradiation. The excess of the Y2 P(O)H reagent (Y=alkoxy, aryl) (30 %) served as the P-ligand in its trivalent tautomeric form (Y2 POH), hence there was no need for the usual P-ligands meaning cost and environmental burden. Hence, the presented method is a "green" approach that proved to be more efficient than the preparation by the traditional method. The products, dialkyl phosphonates and tertiary phosphine oxides obtained in 58-84 % yields were characterized, one of them also by single crystal X-ray analysis, and were subjected to in vitro biological activity evaluation. A (carbazol)yl-phenylphosphonate, an N-phenyl-(carbazol)yl-phosphonate, a (carbazol)yl-phenylphosphine oxide and an N-phenyl-(carbazol)ylphosphine oxide revealed a significant cytotoxic activity on A549 human non-small-cell lung carcinoma and MonoMac-6 acute monocytic leukemia cancer cells. The cytotoxic effect was significant as compared to that of the reference compounds.

Abstract
A metal-free method for the dual activation of aryl phosphinate has been developed; the P-H and P-O bonds are sequentially activated by the Tf2O/DMSO system. Without the requirement of metals and unstable P-reagents, this one-pot procedure provides a convenient and practical access to a variety of aryl phosphonates. A mechanism involving twice generation of electrophilic P-species and two SN-processes is proposed on the basis of the control experiments.

Abstract
A less-studied halogen-free variation of the Hirao reaction involving the coupling of arylboronic acids with >P(O)H reagents, such as diarylphosphine oxides, diethyl phosphite, and ethyl phenyl-H-phosphinate, was investigated in detail using Pd(OAc)2 as the catalyst precursor and applying some excess of the P-reagent to supply the ligand via its trivalent tautomeric (>P-OH) form. The optimum conditions (1.2 equiv of the P-reagent, 135-150 °C, and air) were explored for the synthesis of diaryl-phenylphosphine oxides, aryl-diphenylphosphine oxides, diethyl arylphosphonates, ethyl diphenylphosphinate, and two bisphosphinoyl derivatives. In the reaction of 4-chlorophenyl- or 3-chlorophenylboronic acid with Ph2P(O)H, triphenylphosphine oxide was also formed as a byproduct. Theoretical calculations suggested that the catalytic cycle of the P-C coupling of PhB(OH)2 with Ph2P(O)H is different from that of the usual cross-coupling reactions. It comprises the addition of a phenyl anion and then the tautomeric form >P-OH of the >P(O)H reagent to the Pd2+ catalyst complex. This is then followed by reductive elimination affording Ph3PO that is accompanied with the conversion of Pd2+ to Pd0. There is a need for a subsequent stoichiometric oxidation of Pd(0) by molecular oxygen. The spontaneous formation of the self-assembling ligands around the Pd2+ center from the >P(O)H reactant plays a crucial role in the mechanism and promotes the efficiency of the catalyst.

Abstract
Substituted pyridines with diverse functional groups are important structural motifs found in numerous bioactive molecules. Several methodologies for the introduction of various bio-relevant functional groups to pyridine have been reported, but there is still a need for a single robust method allowing the selective introduction of multiple functional groups. This study reports a ring cleavage methodology reaction for the synthesis of 2-alkyl/aryl 3-electron-withdrawing groups (esters, sulfones, and phosphonates) 5-aminoaryl/phenol pyridines via the remodeling of 3-formyl (aza)indoles/benzofurans. Totally ninety-three 5-aminoaryl pyridines and thirty-three 5-phenol pyridines were synthesized showing the robustness of the developed methodology. The application of this methodology further provided a privileged pyridine scaffold containing biologically relevant molecules and direct drug/natural product conjugation with ethyl 2-methyl nicotinate.

Abstract
Herein, we would like to present deoxyfluorinating reagents such as DAST and PyFluor and their successful use as tools for selective modification of γ-amino-α-hydroxyphosphonates. Depending on the deoxyfluorinating reagent applied, an intramolecular cyclization leading to phosphonates containing the 1,3-oxazinan-2-one moiety or direct nucleophilic deoxyfluorination yielding the α-fluorinated derivatives of γ-aminophosphonates was observed. The obtained compounds may be used as precursors in the preparation of medicinally important compounds e.g., dipeptide analogues or scaffolds containing the 1,3-oxazinan-2-one group.

A highly chemo- and stereoselective synthesis of diethyl (E)-2-(alkylidene)-2-phosphonoacetonitriles via the Knoevenagel condensation reaction of carbonyl compounds with diethyl cyanomethylphosphonate in the presence of zinc chloride has been achieved. By the presented method, various E-isomers of arylmethylidene phosphonates rather than Horner-Wadsworth-Emmons olefination products were obtained in good to excellent yields. Their E configurations were determined by X-ray diffraction and NMR analyses. In addition, DFT calculations provided insights into the chemo- and stereoselectivity of the reaction.

Abstract
Palladium-catalyzed C-P bond formation reaction of ArBr/ArOTf using acylphosphines as differential phosphination reagents is reported. The acylphosphines show practicable reactivity with ArBr and ArOTf as the phosphination reagents, though they are inert to the air and moisture. The reaction affords trivalent phosphines directly in good yields with a broad substrate scope and functional group tolerance. This reaction discloses the acylphosphines' capability as new phosphorus sources for the direct synthesis of trivalent phosphines.

Abstract
We report a general palladium-catalyzed one-pot procedure for the synthesis of phosphonates, phosphinates and phosphine oxides from phenols mediated by sulfuryl fluoride. It features mild conditions, broad substrate scope, high functionality tolerance and water insensitivity. The utility of this procedure has been well demonstrated by gram-scale synthesis, sequential synthesis of click chemistry building blocks, late-stage decoration of drugs and natural products and on-DNA synthesis of phosphine oxide for a DNA-encoded library (DEL).

Abstract
Abstract
The iridium-catalyzed C-H borylation of diethyl phenylphosphonate results in nonselective mono and bisborylation to afford a near statistical mixture of 3-, 3,5- and 4-boryl substituted aryl phosphonates whereas 3-substituted aryl phosphonates undergo highly regioselective C-H borylation to afford the corresponding meta-phosphonate substituted arylboronic esters as the sole product; the resulting boronic esters were used as nucleophilic reagents in a subsequent palladium-catalyzed Suzuki–Miyaura cross-coupling to generate a range of biarylmonophosphonates. Gratifyingly, the Suzuki–Miyaura cross-coupling can be conducted without purifying the boronic ester which greatly simplifies the synthetic procedure.

Abstract
The purpose of this review is to summarize the importance of microwave (MW) irradiation as a kind of catalyst in organophosphorus chemistry. Slow or reluctant reactions, such as the Diels-Alder cycloaddition or an inverse-Wittig type reaction, may be performed efficiently under MW irradiation. The direct esterification of phosphinic and phosphonic acids, which is practically impossible on conventional heating, may be realized under MW conditions. Ionic liquid additives may promote further esterifications. The opposite reaction, the hydrolysis of P-esters, has also relevance among the MW-assisted transformations. A typical case is when the catalysts are substituted by MWs, which is exemplified by the reduction of phosphine oxides, and by the Kabachnik-Fields condensation affording α-aminophosphonic derivatives. Finally, the Hirao P-C coupling reaction may serve as an example, when the catalyst may be simplified under MW conditions. All of the examples discussed fulfill the expectations of green chemistry.

Abstract
The Hirao reaction involving the phosphinoylation or phosphonation of aryl halides by >P(O)H reagents is a P–C bond forming transformation belonging to the recently very hot topic of cross-couplings. The Pd- or Ni-catalyzed variations take place via the usual cycle including oxidative addition, ligand exchange, and reductive elimination. However, according to the literature, the nature of the transition metal catalysts is not unambiguous. In this feature article, the catalysts described for the Pd(OAc)2-promoted cases are summarized, and it is concluded that the “(HOY2P)2Pd(0)” species (Y = aryl, alkoxy) is the real catalyst. In our model, the excess of the >P(O)H reagent served as the P-ligand. During the less studied Ni(II)-catalyzed instances the “(HOY2P)(−OY2P)Ni(II)Cl−” form was found to enter the catalytic cycle. The newest conclusions involving the exact structure of the catalysts, and the mechanism for their formation explored by us were supported by our earlier experimental data and theoretical calculations.

Abstract
Conventionally, the organic reactions are accomplished by conductive heating with an external
heat source like an oil bath. On the contrary, since its inception, the application of microwave
irradiation is growing as a suitable alternate heating method in organic synthesis. Microwave heating
considerably reduces the reaction time without promoting any side reactions. The fundamental synthetic
organic chemistry majorly deals with transition-metal-catalyzed C–C and C–heteroatom bond
formation reactions. It is one of the most important methods in contemporary chemistry resulting in a
tremendous increment in the applications of these reactions during the last few years. This field has
been acknowledged with a number of Nobel Prizes during the last decade (2001, 2005 and 2010). A
considerable effort has been done on the continuous development of new ligands and catalysts as
well as an increased understanding of the mechanisms for the improvement of the reaction condition.
This review focuses on some of the latest developments in the area of cross-coupling reactions aided
by microwave irradiation.

Abstract
:
Organophosphorous compounds are of potential importance in diverse fields. They are often
used as intermediates for making functionalized phosphine ligands as well as find vast applications
in the areas of industrial, agricultural and biological chemistry. The microwave-assisted synthesis
of C-P bonds has become increasingly popular because of its various advantages over conventional
heating in the perspectives of green chemistry.
:
This review article has primarily focused on the synthesis of various organophosphorous molecules
via microwave promoted C-P cross-coupling reactions under metal-catalyzed or metal–free conditions
over the last two decades. The synthesis of phosphine ligands on 4,4′-bisquinolone structural framework,
disubstituted phosphinic acid esters, vinyl phosphines, aryl- and vinylphosphonates, sugar and
nucleoside phosphonates, aminobisphosphonates, triphenyl phosphines, water-soluble tertiary phosphine
oxides and many other potentially useful organophosphorous compounds have been illustrated
critically. The Hirao reaction, Michaelis-Arbuzov reaction and Sandmeyer type of reactions are generally
involved in creating C-P bonds. The role of various metal catalysts, solvents, bases, additives
and temperature in different literatures are carefully discussed.

Abstract
The reactivity order of “iodobenzene > bromobenzene > phenyl trifluoromethanesulfonate”
was established in microwave (MW)-assisted Pd(OAc)2-catalyzed P–C
coupling reactions with diphenylphosphine oxide and diethyl phosphite, where the excess
of the these >P(O)H reagents served as the reducing agent, and, via its tautomeric >P-OH
form, also as the P-ligand. The P–C coupling of Ph2P(O)H with PhBr at 120 °C took place
via an induction period, during which the active “P-Pd-P” catalyst was formed from the
Pd(II) salt and the >P(O)H species. The lower reactivity of PhBr towards Ph2P(O)H could
be promoted by the addition of 20% of KI to the reaction mixture at 120 °C, or utilizing 1
equivalent of KI after a pre-reaction with PhBr at 120-150 °C followed by the P–C coupling
at 100 °C. The reactivity of PhOTf and a bromo analogue was compared in competitive couplings with
Ph2P(O)H. Beyond this, the reactivity of Ph2P(O)H and (EtO)2P(O)H towards PhOTf was evaluated in another
competitive experiment. Increasing the scale of the P–C coupling reaction of (EtO)2P(O)H with PhBr, the
quantity for the components of the catalyst could be decreased.

Abstract
In our current work, we have reported the first cobalt-catalyzed cross-coupling of arylboronic acid with alkyl/aryl phosphites under mild conditions. The reaction was carried out in the presence of zinc powder as an additive and ter-pyridine as a ligand. The use of non-precious cobalt salt makes the protocol advantageous, as it is inexpensive and more abundant than the previously used methods where precious metal salts (Pd and Pt) were used. The reaction has a wide substrate scope and the products were obtained in good yields.

Abstract
Bromopyridines, bromotiophenes and 3-bromofuran were reacted with diphenylphosphine oxide or diethyl phosphite under microwave irradiation using Pd(OAc)2 as the catalyst precursor together with some excess of the >P(O)H reagent. Hence, there was no need for the usual mono- and bidentate P-ligands. The >P(O)-functionalized heterocycles were obtained in variable (55-95%) yields. The results of our “green” protocol were in most cases better than those of the literature methods.

Abstract
Photoinduced transition-metal- and photosensitizer-free cross-coupling of aryl halides (including Ar-Cl, Ar-Br, and Ar-I) with H-phosphonates (including dialkyl phosphonates and diarylphosphine oxides) is reported. Various functional groups were tolerated, including ester, methoxy, dimethoxy, alkyl, phenyl, trifluoromethyl, and heterocyclic compounds. This simple and green strategy provides a practical pathway to synthesize arylphosphine oxides.

Abstract
Abstract
The microwave-assisted Hirao reaction of bromobenzene and diarylphosphine oxides was performed at 120 °C using triethylamine as the base, and 5% of palladium acetate as the catalyst in ethanol. 5% Excess of the >P(O)H reagent served as the reducing agent, while another 10% as the preligand (in the >POH tautomeric form). It was found that the P–C coupling reaction was significantly faster with (2-MeC6H4)2P(O)H (A) and (3,5-diMeC6H3)2P(O)H (B), than with Ph2P(O)H (C) and (4-MeC6H4)2P(O)H (D). Moreover, species A and B could be applied as selective P-ligands in the reaction of bromobenzene with C or D. Dependence of the effectiveness of “PdP2” catalysts with diarylphosphine oxide preligands on the methyl substituents followed a reversed order as the reactivity of the diarylphosphine oxide species in the P–C coupling itself. Formation of the “PdP2” catalyst from palladium acetate and diarylphosphine oxide has never been studied, but now it was evaluated by us at the B3LYP level of theory applying 6-31G(d,p) for C,H,P,O and SDD/MW28 for Pd including the explicit-implicit solvent model. The novel mechanism requiring three equivalents of the >P(O)H species for each of the palladium acetate molecule was in agreement with the preparative experiments. The ligation of palladium(0) with different P(III) species comprising the >POH form of the >P(O)H reagent was also studied, and the critical role of the steric hindrance on the ligation, and hence on the activity of the “PdP2” catalyst was substantiated. Last but not least, the influence of the Me substituents in the aromatic ring of the P-reagents on the energetics of the elemental steps of the Hirao reaction itself was also evaluated.

Abstract
Phosphonates have garnered considerable attention for years owing to both their singular biological properties and their synthetic potential. State-of-the-art methods for the preparation of mixed phosphonates, phosphonamidates, phosphonothioates, and phosphinates rely on harsh and poorly selective reaction conditions. We report herein a mild method for the modular preparation of phosphonylated derivatives, several of which exhibit interesting biological activities, that is based on chemoselective activation with triflic anhydride. This procedure enables flexible and even iterative substitution with a broad range of O, S, N, and C nucleophiles.

Abstract
Visible-light photocatalysis has evolved over the last decade into a widely used method in organic synthesis. Photocatalytic variants have been reported for many important transformations, such as cross-coupling reactions, α-amino functionalizations, cycloadditions, ATRA reactions, or fluorinations. To help chemists select photocatalytic methods for their synthesis, we compare in this Review classical and photocatalytic procedures for selected classes of reactions and highlight their advantages and limitations. In many cases, the photocatalytic reactions proceed under milder reaction conditions, typically at room temperature, and stoichiometric reagents are replaced by simple oxidants or reductants, such as air, oxygen, or amines. Does visible-light photocatalysis make a difference in organic synthesis? The prospect of shuttling electrons back and forth to substrates and intermediates or to selectively transfer energy through a visible-light-absorbing photocatalyst holds the promise to improve current procedures in radical chemistry and to open up new avenues by accessing reactive species hitherto unknown, especially by merging photocatalysis with organo- or metal catalysis.

Abstract
A strategy for the direct functionalization strategy of inertial dialkyl phosphonates with hydroxy compounds to afford diverse mixed phosphonates with good yields and functional-group tolerance has been developed. Mechanistic investigations involving both NMR studies and DFT studies suggest that an unprecedented highly reactive PV species (phosphoryl pyridin-1-ium salt), a key intermediate for this new synthetic transformation, is generated in situ from dialkyl phosphonate in the presence of Tf2 O/pyridine.

Abstract
![]()
We
report the synthesis of guanosine 5′-(4-methylimidazolyl)phosphonate
(ICG), the third member of a series of nonhydrolyzable nucleoside
5′-phosphoro-2-methylimidazolide (2-MeImpN) analogues designed
for mechanistic studies of nonenzymatic RNA primer extension. The
addition of a 2-MeImpN monomer to a primer is catalyzed by the presence
of a downstream activated monomer, yet the three nonhydrolyzable analogues
do not show catalytic effects under standard mildly basic primer extension
conditions. Surprisingly, ICG, which has a pKa similar to that of 2-MeImpG, is a modest catalyst of nonenzymatic
primer extension at acidic pH. Here we show that ICG reacts with 2-MeImpC
to form a stable 5′–5′-imidazole-bridged guanosine-cytosine
dinucleotide, with both a labile nitrogen–phosphorus and a
stable carbon–phosphorus linkage flanking the central imidazole
bridge. Cognate RNA primer–template complexes react with this
GC-dinucleotide by attack of the primer 3′-hydroxyl on the
activated N–P side of the 5′-5′-imidazole bridge.
These observations support the hypothesis that 5′–5′-imidazole-bridged
dinucleotides can bind to cognate RNA primer–template duplexes
and adopt appropriate conformations for subsequent phosphodiester
bond formation, consistent with our recent mechanistic proposal that
the formation of activated 5′–5′-imidazolium-bridged
dinucleotides is responsible for 2-MeImpN-driven primer extension.
