摘要
PROBLEM TO BE SOLVED: To obtain the subject new compound useful as an intermediate for synthesizing a compound which is a developer for heat-sensitive recording materials. ;SOLUTION: A 4,4'-dihydroxydiphenylsulfone diether derivative of formula I (R1, R2 are each H, methyl, ethyl; R3 is an alkyl, an alkenyl, a cycloalkyl), e.g. 4-isopropyloxy-4'benzyloxydiphenylsulfone. The compound of formula I can easily be obtained from a known 4,4'-dihydroxydiphenylsulfone monobenzylether derivative. The compound of formula I can be subjected to a hydrogenolysis reaction to obtain 4,4'-dihydroxydiphenylsulfone monoether of formula II in a high purity and in a high yield. The compound of formula I exhibits an effect to obtain the objective product in a simple process without requiring a complicated separative purification operation.;COPYRIGHT: (C)1998,JPO
