Abstract: Polyhalobenzylic disulfooxonium compounds are produced by the reaction of aromatic methyl, halomethyl or hydroxymethyl substituents with sulfur trioxide. The disulfooxonium salts are readily converted to alcohols by hydrolysis to provide monomers for the production of fire resistant polymers and additives for polymers. Likewise, the disulfooxonium compounds of this invention present chemical intermediates for a wide range of useful products such as halogenated pesticides.
