ABSTRACT:
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.
