Abstract A copper-catalyzed formation of C–N/N–N bonds using N-phenylbenzamidines with aryl nitriles has been developed and affords a route to 1,3,5-trisubstituted 1H-1,2,4-triazoles in moderate to excellent yields. The method is operationally simple and environmentally benign with a large substrate scope available and represents an economical path for numerous C–N/N–N bond formations. A copper-catalyzed
摘要 已开发出使用N-苯基苯甲with与芳基腈的铜催化C–N / N–N键形成方法,并为中,优至1,3,5-三取代1 H -1,2,4-三唑的制备提供了途径产量。该方法操作简便,对环境无害,可提供较大的底物范围,代表了许多C–N / N–N键形成的经济途径。 已开发出使用N-苯基苯甲with与芳基腈的铜催化C–N / N–N键形成方法,并为中,优至1,3,5-三取代1 H -1,2,4-三唑的制备提供了途径产量。该方法操作简便,对环境无害,可提供较大的底物范围,代表了许多C–N / N–N键形成的经济途径。
