Chemistry of gem-Difluorovinyl Sulfonates

Among various emerging organofluorine molecules, gem-difluorovinyl sulfonates are attractive building blocks and less used in organic reactions. This review article is concerned with recent advances in organic reactions using gem-difluorovinyl sulfonates in recent years. We discussed the reactions of gem-difluorovinyl sulfonates with aldehydes, amines, imines, amides, boronic acids, aryl halides, etc. or addition, reduction, substitution and intramolecular 1,3-sulfonyl migration of gemdifluorovinyl sulfonates in nine approaches. The synthetic strategies described in this review provided diversely substituted fluorinated molecules.
