الإجراء التجريبي
60 g of t-amylbenzene, 39.5 g of potassium iodate, 81 g of acetic anhydride and 170 ml of dichloromethane were mixed together. Then 66.8 g of conc. sulfuric acid was slowly added dropwise thereinto under ice-cooling. After stirring under ice-cooling for 2 hours, the mixture was stirred at room temperature for additional 10 hours. 500 ml of water was added to the liquid reaction mixture under ice-cooling and the mixture was extracted with dichloromethane. The organic phase was washed with sodium hydrogencarbonate and water and then concentrated to give (4-t-amylphenyl)iodonium sulfate. This sulfate was added to a solution of tetramethylammonium pentafluorobenzenesulfonate in excess. After adding 500 ml of water, the solution was extracted with dichloromethane. Then the organic phase was washed with a 5% aqueous solution of tetramethylammonium hydroxide and water and then concentrated to give di(4-t-amylphenyl)iodonium pentafluorobenzenesulfonate (III-1).
