الإجراء التجريبي

To a solution of diphenylsulfoxide (2.02 g, 10 mmole) in toluene (30 ml), trifluoroacetic anhydride (4.2 g, 20 mmole) was added dropwise at 10° C. or below, then perfluorooctanesulfonic acid (5.0 g, 10 mmole) was added to the mixture, reacted with stirring for 1 hour at 10° C. or below, and then for 2 hours at room temperature. After standing, the oily layer was separated, washed with toluene (30 ml×2) and with n-hexane (30 ml×3) to afford 7.4 g of diphenyl-p-tolylsulfonium perfluorooctanesulfonate as yellow viscous oil.
