Abnormal N-heterocyclic carbene main group organometallic chemistry: a debut to the homogeneous catalysis.
Abnormal N-heterocyclic carbene (aNHC) adducts of zinc(II) (1) and aluminum(III) (2) were synthesized. The compounds were characterized by NMR spectroscopy and elemental analysis. The solid state structures of these complexes (1 and 2) were determined by single crystal X-ray study. Furthermore, these organozinc and organoaluminum adducts (1 and 2) were tested for the ring opening polymerization...
متن کاملFascinating frontiers of N/O-functionalized N-heterocyclic carbene chemistry: from chemical catalysis to biomedical applications.
The in vogue N-heterocyclic carbenes (NHCs) have attracted attention largely for its new found popularity in chemical catalysis and also for displaying promising traits in biomedical applications. The current perspective provides an account of our efforts in exploring the utility of N/O-functionalized N-heterocyclic carbenes in these two areas. On the catalysis front, we have employed the N/O-f...
متن کاملIntercepting low oxidation state main group hydrides with a nucleophilic N-heterocyclic olefin.
The N-heterocyclic olefin, IPr=CH(2) (IPr = [(HCNDipp)(2)C], Dipp = 2,6-(i)Pr(2)C(6)H(3)) has been demonstrated to be of sufficient Lewis basicity to stabilize main group hydrides in unusually low oxidation states.
متن کاملDiverse chemical applications of N-heterocyclic carbenes.
N-Heterocyclic carbenes, or NHCs as they are commonly abbreviated, have attracted significant interest over the past decade due to their widespread utility in chemical transformations. As ligands on transition metals, NHCs have been found to have properties similar to those of the widely employed phosphine ligand, due to their ability to act as both a Lewis base and a Lewis acid at the same tim...
متن کاملN-heterocyclic carbene-catalyzed [3+4] cycloaddition and kinetic resolution of azomethine imines.
The first N-heterocyclic carbene (NHC)-catalyzed [3+4] cycloaddition of azomethine imines and enals is disclosed. Oxidative catalytic remote activation of enals affords 1,4-dipolarophile intermediates that react with 1,3-dipolar azomethine imines to generate dinitrogen-fused seven-membered heterocyclic products with high optical purities. Our approach also provides effective kinetic resolution ...
