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.
