Asymmetric transfer hydrogenation of ketones catalyzed by rhodium and iridium complexes with chiral bidentate Schiff's bases

摘要

Rhodium and iridium complexes of Schiff's bases derived from (1R,2R)- and (1S,2S)-di-aminocyclohexane catalyze asymmetric transfer hydrogenation of alkyl aryl ketones in Pr~iOH at room temperature to give chiral secondary alcohols (up to 65% ee).
