Vic-Difluorination proceeds by the reaction of fluoroalkenes with xenondifluoride to afford the corresponding fluorinated compounds. From the reaction with polyfluoroalkenes, the products are obtained in high to excellent yields. In this reaction, the fluorine atom substituent of alkene stabilizes the cation intermediate and suppresses side-reactions such as rearrangement.

The geminal-difluoro hydrofluorocarbons (HFCs) were fluorinated by the use of cobalt trifluoride (CoF3). Regioselective monofluorination of geminal-difluoro compound was achieved on methylene position neighboring gem-difluoromethylene group, and trifluoro compounds were obtained in good yields under mild conditions.
