50 g of diphenyl sulfoxide was dissolved in 800 ml of benzene and thereto, 200 g of aluminum chloride was added and refluxed for 24 hours. The reaction solution was gradually poured into 2 L of ice and thereto, 400 ml of concentrated hydrochloric acid was added and heated at 70° C. for 10 minutes. This aqueous solution was washed with 500 ml of ethyl acetate and filtered. Thus, a solution obtained by dissolving 200 g of ammonium iodide was added thereto. The powder precipitated was collected by filtration, washed with water, washed with ethyl acetate and then dried. Thus, 70 g of triphenylsulfonium iodide was obtained.
