标题 :Nucleophilic substitution reactions of difluorormethyl phenyl sulfone with alkyl halides leading to the facile synthesis of terminal 1,1-difluoro-1-alkenes and difluoromethylalkanes

摘要:(Benzenesulfonyl)difluoromethyl anion, in situ generated from difluoromethyl phenyl sulfone and a base, was found to easily undergo nucleophilic substitution reactions (S N 2) with primary alkyl halides, elemental halogens, and perfluoroalkyl halides with good selectivity. The formed (benzenesufonyl)difluoromethylalkanes are useful intermediates for the facile preparation of 1,1-difluoro-1-alkenes and difluoromethylalkanes. Thus, difluoromethyl phenyl sulfone acts as both “CF 2 â•?â€? and “CF 2 H − â€? synthons
