In 200 ml of benzene were dissolved 21.1 g (0.1 mol) of diphenylsulfoxide, and 42.0 g (0.2 mol) of trifluoroacetic acid anhydride were added dropwise thereto at 0 to 5° C., followed by stirring and stirred at 0 to 5° C. for 30 minutes. And then, 15.0 g (0.1 mol) of trifluoromethane sulfonic acid were added dropwise thereto at 0 to 5° C. and allowed to react with stirring at 0 to 20° C. for 3 hours. After completion of the reaction, 500 ml of n-hexane was poured into the resultant and the obtained oily substance separated by decantation was crystallized from methylene chloride/n-hexane, followed by filtration and drying, to give 37.9 g (yield: 92%) of triphenylsulfonium trifluoromethanesulfonate as a white crystal.
