Procedure
A mixture was heated with stirring under nitrogen of 4.6 parts of dibenzothiophene, 9.25 parts of diphenyliodonium fluoroborate and 0.2 part of copper benzoate at 210° C. for 30 minutes. The reaction mixture was allowed to cool to room temperature resulting in a crystalline product. The product was washed several times with anhydrous diethylether and then collected by filtration. Recrystallization from methylene chloride-ethyl ether gave a 55% yield of pure S-phenyldibenzothiophenium fluoroborate having a melting point of 237°-242° C. and the formula,
