An enantioselectivehydrogenation of N-substituted diarylmethanimines under mild conditions has been first realized by using an iridiumcatalyst with a chiral f-spiroPhos ligand. This method provides an efficientaccess to the asymmetric synthesis of a variety of chiral diarylmethylamines and their derivatives with excellent enantioselectivities (up to 99.4% ee) and high turnover numbers (TON up to
