실험 절차

Acetonitrile (500 ml) was added to triphenylsulfonium iodide (390.3 g; 1.0 mol) and methyl p-toluenesulfonate (223.5 g; 1.2 mol). The resultant mixture was heated at 82° C.-85° C. and refluxed for 5 hours while being stirred. The reaction mixture was cooled, and acetonitrile was removed through distillation under reduced pressure. The thus-obtained pale-yellow solid was washed with methylene chloride, and dried under vacuum, to thereby yield 369.4 g of triphenylsulfonium p-toluenesulfonate (yield: 85%).
