无论是在实验室还是工业生产中,通过胺的选择性氧化制备亚胺类化合物都具有重要的意义.秉承原子经济性、环境友好的理念,以蝴蝶型络合物Cu2(ophen)2为催化剂,实现了需氧型的胺的选择性氧化.值得注意的是,该催化体系对醇与胺的氧化交叉偶联、一级胺的氧化偶联和二级胺的氧化脱氢反应都是有效的.反应产率高达93%,亚胺的选择性高达99%.在反应体系中,避免了昂贵的氮氧自由基类化合物的使用,使得该体系更具有潜在的实际应用价值.

The selective catalytic oxidation of amines for the synthesis of imines is important both in laboratory and industrial production. From atom-efficient, economic and environmental view of points, dioxygen selective oxidation of amines was achieved by using wings-opened butterfly-like complex Cu2(ophen)2 as catalyst. It was worth noting that the catalytic system was efficient to the cross-coupling of alcohols with amines, homocoupling of primary amines and oxidative dehydrogenation of secondary amines. The yield is up to 93% and the selectivity of imines is as high as 99%. Avoiding the use of expensive nitroxyl derivatives and base was suitable for practical application.

Key words: aerobic oxidation, dinuclear Cu-complex, base-free, N-O radical free, high selectivity
