摘要：

The new amido complex OsH(NHCMe2CMe2NH2)(PPh3)(2) (2) reacts with weak acids HX to give complexes OsHX(tmen)(PPh3)(26) (1; X = Cl, 3; X = NCCHCN, and X = H; tmen = NH2CMe2CMe2NH2) and is an active ketone hydrogenation catalyst. HX is completely transferred from Os to Ru in the reactions of the amido complex RuH(NHCMe2CMe2NH2)(PPh3)(2) with complexes 1 and 3.
