According to the generally held view the AdE-reaction of sulfenyl halides with alkenes proceeds via intermediate formation of episulfonium ions /I/. One of the peculiar features of this reaction is the preferential formation of anti-Markovnikov's adducts for the additions to unsymmetrical alkenes. T
