Rhenium(I)-NH complexes featuring bidentate PN, tridentate PNP, and tetradentate PNNP ligands were employed as catalysts for the transfer hydrogenation of ketones and aldehydes to alcohols. The structure of the phosphinoamine ligand significantly influenced the transfer hydrogenation performance of the resulting complexes, among which complex HN(CH2CH2PPh2)2Re(CO)2Cl (7) exhibited the highest activity. Following optimization of key factors including catalyst loading, additive, and temperature, activity tests demonstrated that 7 could efficiently catalyze the transfer hydrogenation of nearly 50 diverse ketones and aldehydes to their corresponding alcohols. Under suitable conditions, complex 7 also enabled the chemoselective hydrogenation of unsaturated aldehydes to afford unsaturated alcohols in high efficiency.
