Biswas, Soumik;Blessent, Michael J.;Gordon, Benjamin M.;Zhou, Tian;Malakar, Santanu;Wang, David Y.;Krogh-Jespersen, Karsten;Goldman, Alan S. research published 《 Origin of Regioselectivity in the Dehydrogenation of Alkanes by Pincer-Iridium Complexes: A Combined Experimental and Computational Study》, the research content is summarized as follows. PCP-pincer (κ³-2,6-C₆H₃(CH₂PR₂)₂) iridium complexes have been reported to catalyze the transfer dehydrogenation of n-alkanes with high regioselectivity for the terminal position. We find that the very closely related PCOP (κ³-2,6-C₆H₃(CH₂PR₂)(OPR₂)) and POCOP (κ³-2,6-C₆H₃(OPR₂)₂) complexes, in contrast, afford no such regioselectivity. The difference is a true kinetic phenomenon, i.e., it is not a result of isomerization subsequent to the formation of free α-olefin. In addition to direct observation of the distribution of n-alkane dehydrogenation products over time, the pronounced difference in regioselectivity is confirmed through intermol. competition studies of the reverse reaction (olefin transfer hydrogenation) and of the dehydrogenation of cycloalkane vs n-alkane. Electronic structure (DFT) calculations indicate that the rate- and selectivity-determining step for dehydrogenation by the (PCP)Ir complexes is β-H transfer. C-H activation at the primary position is much more favorable than at secondary positions, but this is not responsible for the terminal regioselectivity; indeed, the formation of α-olefin via C2-H addition and transfer of the C1-H bond is calculated to be slightly more favorable than dehydrogenation proceeding via C1-H addition For both PCP and POCOP complexes, the formation of the α-olefin iridium dihydride complex is more facile than the formation of internal-olefin complexes. The next step in the catalytic pathway, loss of olefin, is calculated to have an activation energy that is significantly greater than the metal-ligand (thermodn.) bond energy. In the case of POCOP complexes, the loss of olefin, rather than β-H transfer, is the rate- and selectivity-determining step. The hydrocarbon moiety in the transition state for olefin loss has the character of a fully formed olefin; this favors the formation of internal olefin. The different regioselectivity of (POCOP)Ir vs (PCP)Ir catalysts is thus attributable to the different rate-determining steps of their resp. catalytic cycles; this in turn can be explained in terms of different electronic effects of O vs. CH₂ linker exerted through the pincer aromatic ring.

Bi, Shuai;Zhang, Zixing;Meng, Fancheng;Wu, Dongqing;Chen, Jie-Sheng;Zhang, Fan research published 《 Heteroatom-Embedded Approach to Vinylene-Linked Covalent Organic Frameworks with Isoelectronic Structures for Photoredox Catalysis》, the research content is summarized as follows. Embedding heteroatoms into the main backbones of polymeric materials has become an efficient tool for tailoring their structures and improving their properties. However, owing to comparatively harsh heteroatom-doping conditions, this has rarely been explored in covalent organic frameworks (COFs). Herein, upon aldol condensation of a trimethyl-substituted pyrylium salt with a tritopic aromatic aldehyde, a two-dimensional oxonium-embedded COF with vinylene linkages was achieved, which was further converted to a neutral pyridine-cored COF by in situ replacement of oxonium ions with nitrogen atoms under ammonia treatment. The two heteroatom-embedded COFs are conceptually isoelectronic with each other, featuring similar geometric structures but different electronic structures, rendering them capable of catalyzing the visible-light-promoted multi-component synthesis of tri-substituted pyridine derivatives with good recyclability.

The coordination chem. of the anionic NHC 1^– based on an imidazo[1,5-a]pyridin-3-ylidene (IPy) platform substituted at the C5 position by an anionic barbituric heterocycle was studied with d⁶ (Ru(II), Mn(I)) and d⁸ (Pd(II), Rh(I), Ir(I), Au(III)) transition-metal centers. While the anionic barbituric heterocycle is planar in the zwitterionic NHC precursor 1·H, NMR spectroscopic analyses supplemented by x-ray diffraction studies evidenced the chelating behavior of ligand 1^– through the carbenic and the malonic C atoms in all of the complexes, resulting from a deformation of the lateral barbituric heterocycle. The complexes were obtained by reaction of the free carbene with the appropriate metal precursor, except for the Au(III) complex 10, which was obtained by oxidation of the antecedent Au(I) complex [AuCl(1)]^– with PhICl₂ as an external oxidant.
