NBS(N-溴代丁二酰亚胺)的应用对烯丙位和苄位上的特殊溴化提供了一个极有用的方法。对于这类反应,NBS的特殊价值是由于分子卤素在双键存在下不能完成取代而给出加成,但NBS却能发生取代反应而双键不受干扰。对于这个反应历程直到
The use of NBS (N-bromosuccinimide) provides a very useful method for the special bromination of the allylic and benzylic positions. For this type of reaction, the particular value of NBS is given by the fact that the molecular halogen can not be substituted in the presence of a double bond, but the NBS can undergo a substitution reaction without the double bond being disturbed. For this reaction process until
