Reaction Conditions

Reaction Steps

In 36.1 g (0.3 mole) of mesitylene was dissolved 6.1 g (0.03 mole) of diphenylsulfoxide, and 12.6 g (0.06 mole) of trifluoroacetic anhydride was poured thereinto under cooling at 5° C. or lower and further 4.5 g (0.03 mole) of trifluoromethane sulfonic acid was added dropwise thereto at −5 to 5° C., followed by allowing a reaction to take place at the same temperature for 2 hours with stirring. Into the resultant was poured 20 ml of n-hexane, followed by separation. This process step series was conducted three times and the resulting crude oily substance was crystallized from a mixture of butyl acetate and isopropyl ether and the crystal was recovered by filtration and dried to give 11.5 g (Yield: 84%) of diphenyl-2,4,6-trimethylphenylsulfonium trifluoromethanesulfonate as white crystal.
