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.
