Résumé A rapid and efficient method has been developed for the synthesis of vicinal bromoazide directly from olefin using N-bromosuccinimide (NBS) and trimethylsilyl azide (TMSN3) as the bromine and azide sources, respectively, without any catalyst in acetonitrile as solvent. The rate of reaction is remarkably fast in acetonitrile without catalyst to produce bromoazides in high yield.

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
