Versuchsvorschrift

To a stirred suspension of 4.40 g (20 mmol) of iodosylbenzene in 100 ml of dichloromethane was added dropwise 6.0 g (20 mmol) of nonafluorobutane sulfonic acid at 0° C. under exclusion of moisture. The mixture was stirred at room temperature for 2 hours. The temperature was returned to 0° C. again. 1.84 g (20 mmol) of toluene was added dropwise. After the addition, stirring was continued at room temperature for additional 1 hour. The solvent as evaporated. The oily residue was dissolved in diethyl ether. The solution was cooled to obtain crystals of 4-methylphenyl phenyl iodonium nonafluorobutane sulfonate. The crystals were washed with hexane. The yield was 6.7 g.
