摘要

Abstract Complexation of 2, 7-bis (2-pyridyl)-1, 8-naphthyridine (bpnp) with Cu 2 O in formic acid under aerobic conditions provided a dicopper complex [Cu 2 (bpnp)(μ-OH)(HCOO) 3](1). This complex has been characterized by X-ray crystallographic and spectroscopic analysis. With O 2 as the oxidant, complex 1 is an efficient catalyst for the oxidative coupling of alcohols with amines or diamines, leading to the corresponding imines or diimines in ...
