Abstract It has long been known that arenesulfenyl halides will add to olefins to yield β- halosulfides1. Arene-sulfonyl halides have been shown to react with alkenes2 polyenes3, alkynes4 and allenes5. Although sulfinyl halides have been synthesized for some time6 there appears to be but one brief mention of their reaction with olefins7. In view of the recent increased interest in sulfoxides we decided to reinvestigate this reaction.
