A process for the preparation of perhaloalkanesulfinic and -sulfonic acids and derivatives of these acids. A perhaloalkanesulfinic acid salt is prepared by contacting a metal hydroxymethanesulfinate (preferably, a sodium, zinc or copper hydroxymethanesulfinate) with a perhaloalkyl halide group, in a polar solvent. Optionally, the perhaloalkanesulfinic acid salt is then converted to a perhaloalkanesulfinic or -sulfonic acid or a derivative of either of these acids.

The reaction of perfluoroalkanesulfinates, R(f)CF2SO2Na, with allyl and propargyl halides, in the presence of (NH4)2S2O8, gave 3-(perfluoroalkyl)prop-1-enes (R(f)CH2CH = CH2) and 3-(perfluoroalkyl)allenes (R(f)CH = C = CH2), respectively, in good yield. Evidence is presented for a radical addition-elimination mechanism for the reaction. The reaction represents a synthetically viable and convenient route to such compounds.
