omega-dichloroperfluoroalkanes, the similarly stepwise reactions with an alkene is not clean, both bis-adducts and the corresponding omega-hydrides, RCH(2)CH(2)(CF(2))(n)()H as byproducts are also formed. In the absence of alkenes or alkynes, per- and polyfluoroalkyl chlorides can be converted to their sulfinate salts and sulfonyl chlorides.

Halocarbons such as carbon tetrachloride, CCl3Br, CF3CCl3, BrCF2CF2Br, BrCF2CFClBr and CF2Br2, reacted with olefins in the presence of the sulfinatodehalogenation reagent sodium dithionite under mild conditions to give the corresponding adducts. In the case of F113, CFCl2CF2CFCl2 and CF3Cl3, the polyfluoroalkylation product resulted.
