Abstract

PURPOSE: To obtain the titled compound useful as an intermediate for preparing a resin, a dye, etc. industrially and readily, by oxidizing a specific compound with H2O2 in water and/or a specific organic solvent in the presence of an alkali.
CONSTITUTION: A 4,4'-bisphenol sulfide (n=0) of the formula (R1 and R2 are H, halogen, etc.; n is 0 or 1) or a 4,4'-bisphenol sulfoxide (n=1) of the formula is oxidized with H2O2 in water and/or an organic solvent which will not form an organic peracid in the presence of an alkali in an equimolar amount or more to give a 4,4'-bisphenol sulfone derivative (n=2 in the formula).
EFFECT: Few problems of environmental protection without requiring the use and recovery of expensive metallic catalysts and fear of danger from bumping and explosion. The reaction proceeds smoothly to give the aimed substance in high purity and quantitative yield.
