Procedure

A mixture of 192.22 g of methane sulfonic acid, 54.46 g of bis-(4-methoxyphenyl)sulfoxide and 500 ml of anisole was heated at 80° C. for 22 hours. The mixture was poured into 1000 g of ice water and extracted three times with 500-ml portions of ether. The aqueous phase was neutralized with 50 percent aqueous sodium hydroxide and extracted five times with 500-ml portions of chloroform. The combined chloroform phases were dried with magnesium sulfate and the chloroform was removed on a rotary evaporator to give 105.76 g of tris-(4-methoxyphenyl)sulfonium methane sulfonate with residual chloroform of solvation.
