Abstract In this paper, in addition to introducing efficient method for bromohydrin and bromoether preparation, simple, green and efficient method to CN bond formation from alkene and N, N'-Dibromo-N, N'-1, 2-ethanediyl-bis (p-toluenesulfonamide)[BNBTS] in water was investigated. The reaction between alkenes,-cyclodexterin, and BNBTS took place in water afterward, by making media basic; it will give the corresponding valuable building ...
