ABSTRACT:
A process for preparing bisphenol sulfone derivatives represented by the general formula (I) ##STR1## where R stands for hydrogen, a halogen, an alkyl radical, a cycloalkyl radical, an aryl radical, an aralkyl radical, hydroxyl group, an alkoxy radical, allyloxy group, carboxyl group, or a carboalkoxy radical, m is an integer of from 1 to 3, and when m is 2 or more, R may be identical to or different from each other, and adjacent Rs may be combined to form a ring, by oxidizing with hydrogen peroxide a compound represented by the general formula (II) ##STR2## where R and m have the same meanings as defined for the formula (I), and n is zero or 1, in the presence of an alkali in an amount more than the equimolar amount thereof relative to said compound in water and/or an organic solvent which do not form any organic peracids under reaction conditions.
