Versuchsvorschrift

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. Ether was added to the oil and the mixture was stirred vigorously. A white precipitate formed. The mixture was filtered and recovered precipitate was dried under vacuum, resulting in a white powder; mp 155° C.
