We have developed a general and efficient method for copper-catalyzed amidation of saturated C−H bonds under mild conditions, and the used substrates include benzylic reagents, the N,N-dimethylaniline derivatives, the free carboxamides, and sulfonamides. The protocol uses inexpensive and readily available CuBr/N-halosuccinimide (NBS or NCS) as the catalyst/oxidant, so it provides practical applications
我们已经开发了一种在温和条件下铜催化饱和CH键的酰胺化的通用有效方法,所用的底物包括苄基试剂,N,N-二甲基苯胺衍生物,游离羧酰胺和磺酰胺。该协议使用廉价且容易获得的CuBr / N-卤代琥珀酰亚胺(NBS或NCS)作为催化剂/氧化剂,因此它为通过CH活化合成各种酰胺提供了实际应用。
