摘要

A new chiral ligand N-p-toluenesulfonyl-2,2'-dimethoxy-6,6'-diaminobiphenyl (Ts-DMBDPPA) was prepared from 2, 2'-dimethoxy-6,6'-diaminobiphenyl via N-tosylation. Its Ru(Ⅱ) comnplex was effective catalysts for catalytic asymmetric transfer hydrogenation of aromatic ketones (with ee's up to 69.3%).
