The reduction of imines to amines via transfer hydrogenation was achieved promoted by phosphine‐free manganese(I) catalyst. Using isopropanol as reductant, in the presence of tBuOK (4 mol %) and manganese complex [Mn(CO)3Br(κ2N,N‐PyCH2NH2)] (2 mol %), a large variety of aldimines (30 examples) were typically reduced in 3 hours at 80 °C with good to excellent yield.
不含膦的锰(I)催化剂促进了通过转移氢化将亚胺还原为胺。使用异丙醇作为还原剂,在存在吨丁醇钾(4摩尔%)和锰配合物[锰(CO)3 Br(上κ 2 N,PyCH 2 NH 2)](2摩尔%),大量的各种醛亚胺的(30个实施例)通常在80°C下经过3小时还原,收率良好至极佳。
