Procedure

36 g of diphenyl iodonium perchlorate were dissolved in 500 g of water. To the resulting aqueous solution, gradually and dropwise added were an aqueous solution of 34 g of sodium 9,10-dimethoxyanthracene-2-sulfonate dissolved in 500 g of water. Next, this mixture was stirred for 2 hours and the product was precipitated. This product was taken out by filtration and washed with 200 g of water. Next, this was dried at 40° C. under reduced pressure to obtain 51 g of diphenyliodonium 9,10-dimethoxyanthracene-2-sulfonate (PAG 3-22).
