Catalytic hydrogenation of carboxylic acid esters is essential for the green production of pharmaceuticals, fragrances, and fine chemicals. Herein, we report the efficient hydrogenation of esters with manganese catalysts based on simple bidentate aminophosphine ligands. Monoligated Mn PN complexes are particularly active for the conversion of esters into the corresponding alcohols at Mn concentrations as low as 0.2 mol % in the presence of sub-stoichiometric amounts of KO Bu base.
羧酸酯的催化氢化对于药品、香料和精细化学品的绿色生产至关重要。在此，我们报告了基于简单双齿氨基膦配体的锰催化剂对酯的高效氢化。在 KO Bu 碱的亚化学计量存在下，单核 Mn PN 配合物在锰浓度低至 0.2 mol%时特别有效地将酯转化为相应的醇。
