実験手順

To a suspension of perfluorooctanesulfonic acid potassium salt (10.76 g, 20.0 mmol) in water (100 mL) at room temperature under nitrogen was added dropwise triphenylsulfonium bromide (6.87 g, 20.0 mmol) over 15 min. After stirring the suspension for 30 min., dichloromethane (100 mL) was added and the biphasic mixture stirred at room temperature for 20 h. Additional dichloromethane (100 mL) was added and the layers separated. The organic layer was washed with water (3×75 mL) until the washings were neutral (pH 7). After drying (MgSO4), removal of the solvent in vacuum gave a viscous gum which was further dried by heating at 50° C. for 24 h under vacuum. In this way, triphenylsulfonium perfluorooctanesulfonate was isolated as a pale yellow gummy solid.
