efficient method has been developed for the synthesis of vicinal bromoazides directly from olefin using N,N-dibromo-p-toluenesulfonamide (TsNBr2) without any catalyst. The reaction is extremely fast which goes into completion instantaneously to produce bromoazides. This procedure is applicable to various olefins such as cinnamates, chalcone, styrenes, and acrylate to give the corresponding 1,2-bromoazide
已开发出一种非常快速有效的方法,无需任何催化剂,即可使用N,N-二溴-对甲苯磺酰胺(TsNBr 2)直接从烯烃合成邻位溴叠氮化物。该反应非常快,可立即完成以生成溴叠氮化物。该方法适用于各种烯烃,例如肉桂酸酯,查尔酮,苯乙烯和丙烯酸酯,从而以优异的产率得到相应的1,2-溴叠氮化物。
