Procedure

10.65 g (0.03 mol) of N-p-toluenesulfonyldiphenylsulfilimine were dissolved in 40 ml of dry methylene chloride, and 4.44 g (0.03 mol) of trimethyloxonium tetrafluoroborate were added. After stirring overnight and concentrating, the reaction product formed a crystalline precipitate. Drying under reduced pressure left 11.45 g of the salt (IV). Analysis and properties are indicated in Table 1.
