Procedure

Into a mixture of 6.6 ml of chlorosulfonic acid, 6 ml of antimony pentafluoride and 10 ml of monochloroacetic acid, was added 8.9 ml of benzene at 25° C., and the mixture was stirred for 3 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 50% and 20%, respectively, based on benzene.
