摘要

Abstract An efficient and simple method for the synthesis of various [1, 2, 3] triazolo [1, 5-a] pyridines has been established. The method involves a copper (II)-catalyzed oxidative N [BOND] N bond formation that uses atmospheric oxygen as the terminal oxidant following hydrazonation in one pot. The use of ethyl acetate as the solvent dramatically promotes the oxidative N [BOND] N bond-formation reaction and enables the application of oxidative ...
