Abstract

R3 H or alkyl synthesized by the reaction of 1 with elemental chlorine and sulfuryl chloride in inert solvent^.^ This kind of reaction is often interpreted by Scheme I, but in this case and others7bsf-h the accumulated experimental facts are not consistent with it. Scheme I consists of electrophilic attack of halogen on the sulfur atom with formation of the corresponding chlorosulfonium salt 3 (step a) which subsequently decomposes by nucleophilic attack of ...
