摘要 KBr or NaCl is found to be a good catalyst in Se-Se bond cleavage of diselenides in the present of the oxidant mCPBA.The electrophilic addition of the in situ generated reactive electrophilic selenium species PhSeX（X = Br,Cl） to alkenes in AcOH provides a convenient access to 2-acetoxy-1-selenides.Compared with other catalysts,KBr or NaCl is less expensive and more environment-friendly.
