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
