Perfluorobutane-1,4-disulfonic acid potassium salt (2.5 g) was added to a solution of triphenylsulfonium bromide (3.5 g) in 150 ml of water. Chloroform (150 ml) was added and stirred for 5 hours. The chloroform layer was washed several times with water, dried over anhydrous sodium sulfate, filtered, and the filtrate evaporated to an oil stage.
