Title
High activity iridium catalyst for the asymmetric hydrogenation of aromatic ketones
Abstract

The asymmetric hydrogenation of aromatic ketones catalyzed by iridium complexes was investigated in the presence of chiral damines and achiral phosphines. The catalytic system with triphenylphosphine and 9-amino(9-deoxy)epicinchonine exhibited high activity and enantioselectivity in the asymmetric hydrogenation of simple aromatic ketones. A series of simple aromatic ketones were hydrogenated completely in just 2 h at room temperature with good ee value (up to 87%).
