Procedure
4.4 g (20 mmol) of iodosylbenzene was suspended in 100 ml of dry dichloromethane. The suspension was cooled to 0° C. with stirring. 4.65 g (20 mmol) of 3,3,3,2,1,1-hexafluoropropane sulfonic acid (optionally distilled) was added at the same temperature thereto under exclusion of moisture. The mixture was stirred at room temperature for 3 hours. The temperature of the mixture was returned to 0° C., and 2.68 g (20 mmol) of 4-t-butylbenzene was added thereto at that temperature. The temperature of the mixture was returned to room temperature, followed by stirring for 6 hours. Thereafter, the insolubles were removed by filtration. The solvent was removed from the filtrate. The oily residue was purified by recrystallization (twice) from diethyl ether. The structure was confirmed by 1H-NMR (CDCl3): δ=0.81 (s, 9H), 4.98-5.22 (m[d], 1H), 7.18-7.23 (d, 2H), 7.58-7.65 ppm (m, 7H).
