Abstract

Reaction products of an iridium (III) salt or a hydrate thereof, a diphosphine having secondary phosphine groups and a metal or ammonium chloride, bromide or iodide are excellent hydrogenation catalysts for ketimine. Using chiral diphosphines and prochiral ketimines, diastereoisomeric secondary amines are obtained in high optical yields.
