Procedimiento

Into a four-necked flask were charged 5.06 parts of diphenylsulfoxide and 50.6 parts of toluene, and the mixture was cooled to 2° C. Then, 10.5 parts of trifluoroacetic anhydride and 7.50 parts of perfluorobutanesulfonic acid were added and the mixture was stirred at the same temperature for 60 minutes. After standing, the lower layer was concentrated and diluted with 100 parts of chloroform. The obtained chloroform solution was washed 11 times with 50 parts of ion-exchange water and concentrated to give 12.0 parts of 4-methylphenyldiphenylsulfonium perfluorobutanesulfonate, which is referred to herein as PAG4.
