Du, Tian;Wang, Biwen;Wang, Chao;Xiao, Jianliang;Tang, Weijun research published 《 Cobalt-catalyzed asymmetric hydrogenation of ketones: A remarkable additive effect on enantioselectivity》, the research content is summarized as follows. A chiral cobalt pincer complex, when combined with an achiral electron-rich mono-phosphine ligand, catalyzes efficient asym. hydrogenation of a wide range of aryl ketones, affording chiral alcs. with high yields and moderate to excellent enantioselectivities (29 examples, up to 93% ee). Notably, the achiral mono-phosphine ligand showed a remarkable effect on the enantioselectivity of the reaction.
