Rhenium complexes (Ph2PCH2CH2NH2)Re(CO)3Cl (1), (Ph2PCH2CH2CH2NH2)Re(CO)3Cl (2), (o-Ph2PC6H4NH2)- Re(CO)3Cl (3), [(Ph2PCH2CH2NH2)2Re(CO)2]Cl (4), [(Ph2PCH2CH2CH2NH2)2Re(CO)2]Cl (5), and [(o-Ph2PC6H4NH2)2Re- (CO)2]Cl (6), were applied for the first time in homogeneous catalytic hydrogenation of ketones to alcohols. Complexes with one PN ligand (1~3) and two PN ligands (4~6) exhibited comparable catalytic performance. Using optimal complex 2, the important factors with significant influences on the catalytic activity were well optimized, including the loading of catalyst, additive, temperature, and so on. Under suitable conditions, complex 2 effectively hydrogenated nearly 30 diverse ketones to their corresponding alcohols.
