METHOD FOR PRODUCING HALOGEN-SUBSTITUTED BENZENEDIMETHANOL

Disclosed is a method for producing a halogen-substituted benzenedimethanol represented by the following formula (2) (wherein X1-X4 are as defined below) in which method a halogen-substituted terephthalic acid diester represented by the following formula (1) (wherein R1 and R2 may be the same or different and respectively represent an optionally substituted alkyl group having 1-20 carbon atoms, X1-X4 may be the same or different and respectively represent a halogen atom or the like, and at least one of X1-X4 is a halogen atom) is reacted with a borane compound (borohydride compound) in the presence of an alcohol. Such a method for producing a halogen-substituted benzenedimethanol is characterized in that an alcohol is added into a mixture of the halogen-substituted terephthalic acid diester represented by the above formula (1), the borane compound (borohydride compound) and a solvent.

Polyhalobenzylic disulfooxonium compounds

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.
