将金属中心分别配位双齿PN配体、三齿PNP配体和四齿PNNP配体的Re(I)-NH配合物应用于催化酮和醛的转移加氢制醇反应. 研究发现, 膦胺配体的结构对所构成配合物的转移加氢性能有显著影响, 其中配合物HN(CH2CH2PPh2)2Re(CO)2Cl (7)活性最优. 在系统优化催化剂用量、助剂种类与用量、温度等参数的基础上, 活性测试结果表明, 7能有效催化近50种底物分子(包括芳香酮、脂肪酮、环酮以及芳香醛、脂肪醛)转移加氢制醇. 在合适反应条件下, 7还可以催化不饱和醛的选择性加氢, 高效制备不饱和醇.

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.
