Procedure

Into a mixture of 6.6 ml of chlorosulfonic acid, 12.6 ml of antimony pentachloride and 10 ml of dichloroacetic acid, was added 8.9 ml of benzene at 25° C., and the mixture was stirred for 5 hours. The reaction mixture was transferred into ice water and the precipitated product was extracted with benzene. From the results of analysis, it was confirmed that benzene-sulfonyl chloride and diphenylsulfone were formed in yields of 60% and 30%, respectively, based on benzene.
