反応手順

To an aqueous solution of 11.5 g of the diphenyl-4-hydroxyphenylsulfonium chloride, 22 g of an aqueous 37.5% potassium trifluoromethanesulfonate solution was dropwise added with stirring at room temperature to obtain a white precipitate. The white precipitate was filtered, and then the impurities were washed with distilled water several times, followed by drying under reduced pressure to obtain 10.7 g of the desired diphenyl-4-hydroxyphenylsulfonium trifluoromethanesulfonate.
