Methyl p-toluenesulfonate → Bis(4-tert-butylphenyl)iodonium p-toluenesulfonate

Participants

Reaction Steps

Bis(p-tert-butylphenyl)iodonium acetate (467 mg; 1.0 mmol) and methyl p-toluenesulfonate (204 mg; 1.1 mmol) were suspended in t-butyl methyl ether (5 ml). The suspension was heated at 55° C.-58° C. and refluxed for 5 hours while being stirred. The reaction mixture was cooled, and formed white solid was removed through filtration. The white solid was washed with t-butyl methyl ether, and dried under vacuum, to thereby yield 521 mg of bis(p-tert-butylphenyl)iodonium p-toluenesulfonate (yield: 91%).
