Abstract

AbstractA copper acetate catalyzed oxidative cycloaddition reaction of benzyl and aryl azides with terminal and internal olefins that contain electron‐withdrawing groups (COOR, CONH2, CN, CHO, COR) has been developed. The reaction employs air as the oxidant and does not require any base or additives to afford 1,4‐disubstituted and 1,4,5‐trisubstituted 1,2,3‐triazoles in good to excellent yields with high regioselectivity.
