A 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
已开发出乙酸铜催化苄基和芳基叠氮化物与包含吸电子基团(COOR、CONH2、CN、CHO、COR)的末端和内烯烃的氧化环加成反应。该反应使用空气作为氧化剂,不需要任何碱或添加剂,以良好的收率和高区域选择性提供 1,4-二取代和 1,4,5-三取代的 1,2,3-三唑。
