Facile Synthesis of α-Chlorosulfoxide Using the N,N'-Dichloro-p-toluenesulfonamide
Various unsymmetrical and symmetrical dialkyl sulfoxides or alkyl aryl sulfoxides reacted with N,N'-dichloro-p-toluenesulfonamide to yield the corresponding α-chlorosulfoxide in excellent yields under mild and neutral conditions in high regioselectivity of monochlorination at α-position of sulfoxides.
