Abstract
To realize the goal of a carbon-free energy economy, it is crucial to discover reactions that utilize sustainable resources as alternatives to fossil feedstocks. In this study, a well-defined, air-stable Cp*Co(III)-catalyst for transfer hydrogenation of quinoline derivatives and oxidative dehydrogenation of cyclic amines in water is developed. While the former reaction is promoted by formic acid as a transfer hydrogenation reagent, the latter is mediated by molecular oxygen as the sole oxidant. These processes provide new avenues for the investigation of air-stable cobalt catalysts for environmentally benign hydrogenation and dehydrogenation reactions.

Abstract
The catalytic acceptorless dehydrogenation (ADH) of saturated N-heterocycles has recently gained considerable attention as a promising strategy for hydrogen release from liquid organic hydrogen carriers (LOHCs). Recently, a simple tBuOK base-promoted ADH of N-heterocycles was developed by Yu et al. (Adv. Synth. Catal. 2019, 361, 3958). However, it is still open as to how the tBuOK plays a catalytic role in the ADH process. Herein, our density functional study reveals that the tBuOK catalyzes the ADH of 1,2,3,4-tetrahydroquinoline (THQ) through a quasi-metal-ligand bifunctional catalytic channel or a base-catalyzed pathway with close energy barriers. The hydride transfer in the first dehydrogenation process is determined to be the rate determining step, and the second dehydrogenation can proceed directly from 34DHQ regulated by the tBuOK. In addition, the computational results show that the cooperation of a suitable alkali metal ion with the tBuO- group is so critical that the tBuOLi and the isolated tBuO- are both inferior to tBuOK as a dehydrogenation catalyst.

Abstract
Molecular hydrogen (H2) is one of the most important energy carriers. In the midterm future, a huge amount of H2 will be produced from a variety of hydrocarbon sources through conversion and removal of contaminants such as CO and CO2. However, bypassing these purification processes is desirable, given their energy consumption and environmental impact, which ultimately increases the cost of H2. Here, we demonstrate a strategy to separate H2 from a gaseous mixture of H2/CO/CO2/CH4 that can include an excess of CO and CO2 relative to H2 and simultaneously store it in N-heterocyclic compounds that act as liquid organic hydrogen carriers (LOHCs), which can be applied to produce H2 by subsequent dehydrogenation. Our results demonstrate that LOHCs can potentially be used for H2 purification from CO- and CO2-rich crude H2 in addition to their well-established use in H2 storage.

Abstract
Quinazoline compounds demonstrate a variety of physiological and pharmacological activities. However, the most common syntheses require large quantities of oxidants, high temperature, and other extreme conditions. In this study, quinazoline compounds were synthesized from the condensation of α-keto acid and 2-aminobenzylamine and then decarboxylation under blue LED irradiation at room temperature without transition metal catalysts or additives. Therefore, we demonstrated that by using α-keto acid as the acyl source, decarboxylation can be realized under blue LED without oxidants, in a simple, mild, and environmentally friendly process.

Abstract
Bio-active molecules having N-heteroarene core are widely used for numerous medicinal applications and as lifesaving drugs. In this direction, dehydrogenation of partially saturated aromatic N-heterocycles shows utmost importance for the synthesis of heterocycles. This feature article highlights the recent advances, from 2009 to April 2021, on the dehydrogenation of N-heteroaromatics. Notable features considering the development of newer catalysis for dehydrogenations are: (i) approaches based on precious metal catalysis, (ii) newer strategies and catalyst development technology using non-precious metal-catalysts for N-heterocycles having one or more heteroatoms, (iii) Synthesis of five or six-membered N-heterocycles using photocatalysis, electrocatalytic, and organo-catalytic approaches using different homogeneous and heterogeneous conditions' (iv) metal free (base and acid-promoted) dehydrogenation along with I2, N-hydroxyphthalimide (NHPI) and bio catalyzed miscellaneous examples have also been discussed, (v) mechanistic studies for various dehydrogenation reactions and (vi) synthetic applications of various bio-active molecules including post-drug derivatization are discussed.

Abstract
![]()
Metal complexes incorporating
proton-responsive ligands have been
proved to be superior catalysts in reactions involving the H2 molecule. In this contribution, a series of IrIII complexes
based on lutidine-derived CNNH pincers containing N-heterocyclic
carbene and secondary amino NHR [R = Ph (4a), tBu (4b), benzyl (4c)] donors
as flanking groups have been synthesized and tested in the dehydrogenation
of ammonia–borane (NH3BH3, AB) in the
presence of substoichiometric amounts (2.5 equiv) of tBuOK. These preactivated derivatives are efficient catalysts in AB
dehydrogenation in THF at room temperature, albeit significantly different
reaction rates were observed. Thus, by using 0.4 mol % of 4a, 1.0 equiv of H2 per mole of AB was released
in 8.5 min (turnover frequency (TOF50%) = 1875 h–1), while complexes 4b and 4c (0.8 mol %)
exhibited lower catalytic activities (TOF50% = 55–60
h–1). 4a is currently the best performing
IrIII homogeneous catalyst for AB dehydrogenation. Kinetic
rate measurements show a zero-order dependence with respect to AB,
and first order with the catalyst in the dehydrogenation with 4a (−d[AB]/dt = k[4a]). Conversely, the reaction with 4b is second order in AB and first order in the catalyst (−d[AB]/dt = k[4b][AB]2).
Moreover, the reactions of the derivatives 4a and 4b with an excess of tBuOK (2.5 equiv) have
been analyzed through NMR spectroscopy. For the former precursor,
formation of the iridate 5 was observed as a result of
a double deprotonation at the amine and the NHC pincer arm. In marked
contrast, in the case of 4b, a monodeprotonated (at the
pincer NHC-arm) species 6 is observed upon reaction with tBuOK. Complex 6 is capable of activating H2 reversibly to yield the trihydride derivative 7. Finally, DFT calculations of the first AB dehydrogenation step
catalyzed by 5 has been performed at the DFT//MN15 level
of theory in order to get information on the predominant metal–ligand
cooperation mode. Iridium complexes
based on CNNH ligands containing
two potential proton-responsive sites—a lutidine scaffold and
a secondary amino group—have been tested in the dehydrogenation
of ammonia-borane. Upon reaction with base, depending on the amino
group acidity, mono- or doubly deprotonated species exhibiting significantly
different catalytic activities were observed.
