Procedure

Under ice-cooling, 25 g of pentafluorobenzenesulfonyl and 66.8 g of concentrated sulfuric acid was gradually dropwise added to the mixture with ice-cooling. The mixture was stirred with ice-cooling for 2 hours and then at room temperature for 10 hours. With ice-cooling, 500 ml of water was added to the reaction solution, followed by extraction with dichloromethane. The organic phase was washed with sodium bicarbonate and water and then concentrated, thereby a di (4-t-amylphenyl) iodonium sulfate was obtained. The sulfate was added to a solution containing an excess amount of tetramethylammonium pentafluorobenzenesulfonate. Water (500 ml) was added to the solution, followed by extraction with dichloromethane. The organic phase was washed with a 5% aqueous solution of tetramethylammonium hydroxide and water, and then concentrated, thereby di (4-amylphenyl) iodonium pentafluorobenzenesulfonate was obtained.
