A mixture of 5.8 g of bis-(4-phenoxyphenyl)sulfoxide and 2.55 g of diphenyl ether in 18 ml of methylene chloride was added dropwise over a period of 3 hours to 7.21 g of methane sulfonic acid at 100° C. The methylene chloride was distilled off as the addition proceeded. The mixture was then heated at 100° C. for 28 hours and worked up substantially according to the procedure previously described to give 7.74 g of tris-(4-phenoxyphenyl)sulfonium methane sulfonate (81.3 percent yield).
