vic-Difluorination proceeds by the reaction of fluoroalkenes with xenon difluoride 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 mechanism of the reaction of OH radicals with C2H5F was determined from the yields of the reaction products.Hydroxyl radicals were generated in the gas phase by photolysis of H2O at 184.9 nm, and products were analyzed by gas chromathography and mass spectrometry.The reaction proceeds by abstraction of hydrogen primarily from the α position, and the major products were meso- and d,l-2,3-C4H8F2, 1,3-C4H8F2, 2-C4H9F, and H2.The minor products were 1,4-C4H8F2, 1-C4H9F, 1-and 2-C3H7F, C2H6, C2H4, C2H3F, and C2H2.It was found that kinetically hot H atoms formed in the photolysis of H2O abstract hydrogen to some extent at the β position of C2H5F in contrast to thermal H atoms which abstract exclusively at the α position.After correction for the effects of H atom reactions, it was estimated that 85+/-3percent of the abstraction by occurs at the α position of C2H5F.
