Recently I am researching about MEDIATED ASYMMETRIC-SYNTHESIS; C-H AMINATION; IMIDAZOLIUM SALT; METAL; COMPLEX; BINDING, Saw an article supported by the Deutsche ForschungsgemeinschaftGerman Research Foundation (DFG) [ME 1805/15-1]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Winterling, E; Ivlev, S; Meggers, E. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride. Application In Synthesis of Benzoic anhydride
We recently reported a new class of chiral ruthenium catalysts in which two achiral bidentate N-(2-pyridyl)-substituted N-heterocyclic carbene ligands in addition to two labile acetonitriles are coordinated to a central ruthenium and generate a stereogenic metal center which is responsible for the overall chirality (Zheng et al. J. Am. Chem. Soc. 2017, 139, 4322). Here we now report our discovery of related chiral-at-ruthenium catalysts in which normal and abnormal N-heterocyclic carbene (NHC) ligands are present at the same time. The synthesis of racemic complexes, their resolution into individual enantiomers by a chiral auxiliary approach, and a catalytic application are reported. The mixed normal/abnormal NHC complexes display significantly increased turnover numbers and turnover frequencies for a nitrene-mediated enantioselective C(sp(3))-H amination.
