ABSTRACT:
Catalysts of formulain-line-formulae description="In-line Formulae" end="lead"?[Ru(L)m(L′)wXY]  (II)in-line-formulae description="In-line Formulae" end="tail"?wherein X and Y represent simultaneously or independently a hydrogen or halogen atom, a hydroxy group, or an alkoxy, carboxyl or other anionic radical, m is 1 or 2, w is 1 when m is 1 and w is 0 when m is 2, L is a phosphino-amine or phosphino-imine bidentate ligand and L′ a diphosphine, are useful for the hydrogenation of substrates having a carbon-hetero atom double bond.
