Abstract
![]()
The use of the bis(1-piperidinyl)-substituted carbodiphosphorane
(Ph2(Pip)P)2C (1) as an NCN ligand for the
stabilization of phosphorus cations was studied. A simple ligand for halide exchange
allowed the synthesis and isolation of a series of phosphorus monocations of the type
[1-PR2]+ (with R = Cl, Br, I, CyCl, Ph). These
cations exhibit characteristic NMR and structural properties which nicely correlate with
the charge at the central phosphorus atom and the interaction between the ligand and the
PR2 moiety. Halide abstraction from the monocations does not result in
isolable dicationic compounds but in an unexpected intramolecular
Csp3–H activation in the piperidinyl group. DFT studies
show that the selective activation of the CH2 group next to the nitrogen atom
instead of a CH group at the phenyl substituents proceeds via an iminium intermediate
formed by hydride transfer from the carbon atom to the cationic phosphorus center. This
observation clearly demonstrates the pronounced π acidity of the dicationic
phosphorus species in comparison to compounds with a further π-donor
substituent.

Abstract
This review is dedicated to the chemistry of stable and isolable species that bear two lone pairs at the same C center, i.e., geminal dianions, stabilized by main group elements. Three cases can thus be considered: the geminal-dilithio derivative, for which the two substituents at C are neutral, the yldiide derivatives, for which one substituent is neutral while the other is charged, and finally the geminal bisylides, for which the two substituents are positively charged. In this review, the syntheses and electronic structures of the geminal dianions are presented, followed by the studies dedicated to their reactivity toward organic substrates and finally to their coordination chemistry and applications.

Abstract
The synthesis and structures of a series of M/X carbenoids of the type [Ph2 P(S)]2 CMX with M=Li, Na, and K and X=Cl and Br are reported, amongst the first isolated Na/Br and K/Br carbenoids. NMR spectroscopic as well as crystallographic studies showed distinct differences between the lithium carbenoids and their heavier congeners. In the solid state, all carbenoids showed no direct metal-carbon interaction, but an interaction between the metal and the halogen atom. This contact is only very weak in the case of the Li/Br carbenoid, but much more pronounced in the corresponding potassium and sodium compounds. Nevertheless, these interactions did not significantly influence the stability of the carbenoids by weakening the C-X bond and facilitating the MX elimination. As such all compounds were found to be stable up to approximately 60 °C in solution. Hence, M-X interactions-albeit being an essential feature for the structure formation of carbenoids-are not the only criterion determining the stability of such compounds. In the present systems, the stabilization by the thiophosphinoyl moieties is more important than the metal/halogen combination.

Abstract
Although Li/Cl carbenoids are versatile reagents in organic synthesis, the controlled handling of the extremely reactive and labile M/F carbenoids remains a challenge. We now show that even these compounds can be stabilized and isolated in solid state, as well as in solution. Particularly the sodium and potassium compounds exhibit a remarkable stability, thus allowing the first isolation of a room-temperature-stable fluorine carbenoid. Spectroscopic, as well as DFT studies confirmed the pronounced carbenoid character, showing M-F-C interactions with elongated C-F bonds. The different stabilities of the carbenoids was found to originate from the different strength of the M-F interaction. Hence, the lithium compounds are considerably more reactive than their heavier congeners. Reactivity studies showed that the nature of the metal also influences the reactivity, resulting in different selectivity in the addition to thioketones.

Abstract
Metal carbenoids such as lithium or Simmons-Smith-type reagents are widely used in organic synthesis, particularly in cyclopropanation and homologation reactions. These reagents are often highly reactive and thermally labile, thus limiting their isolation and hampering the development of new synthetic applications. Recent years however, have shown that by means of systematic stabilization a control of reactivity and the development of new applications is possible. This feature article documents recent developments in the control of carbenoid reactivity and stability and highlights structural and electronic properties as well as applications in main group element and transition metal chemistry.
