Water → 4-[(4-Hydroxyphenyl)disulfanyl]phenol

Participants

Reaction Steps

25.0 g of para-hydroxy thiophenol (Wako Pure Chemical Industries, Ltd.) was dissolved in 100 ml of dimethyl sulfoxide (Kanto Chemical Co., Ltd.) at 0 degree C. The reaction solution was stirred for 24 hours at 65 degree C. and cooled to 0 degree C. after the completion of the reaction. Then the mixture was diluted with 100 ml of diethyl ether (Wako Pure Chemical Industries, Ltd.). Water was added to this solution and the aqueous phase was extracted with 50 ml of diethyl ether three times. Then the organic phase was dried by using sodium sulfate (Wako Pure Chemical Industries, Ltd.) and recrystallized in chloroform (Wako Pure Chemical Industries, Ltd.). 4,4′-disulfanediyldiphenol was obtained (23.8 g, yield 96%).
