Yield:61358-25-6 69%

Reaction Conditions:

with potassium hexafluoridophosphate in ethanol at 20; for 2 h;

Steps:

4

16.1g of tert-butylbenzene, 5.1g of elemental iodine, 10.3g of p-toluenesulfonic acid and 50mL of dichloroethane were sequentially added to a 250mL round-bottomed flask, and then 10.3g of 50% hydrogen peroxide was slowly added dropwise under stirring conditions, and then heated to The reaction was carried out at 60°C for 48 hours. After the reaction was completed, the solid was removed by filtration. After the filtrate was washed with water and desolubilized, 15.8 g of the intermediate bis(4-tert-butylphenyl) iodonium p-toluenesulfonate was obtained; 15.8 g of the obtained The intermediate bis(4-tert-butylphenyl) iodonium p-toluenesulfonate was dissolved in 10 mL of ethanol, and then a saturated potassium hexafluorophosphate solution (14.7 g of potassium hexafluorophosphate was dissolved in 200 mL of water) was added dropwise to it under stirring conditions. ), stirred at room temperature for 2 hours, after the solid was precipitated in the solution, suction filtration to obtain 14.9g of the product bis(4-tert-butylphenyl)iodonium hexafluorophosphate, the yield was 69%
