Reaktionsschritte

A mixture of 11.75 parts of diphenyl iodonium hexafluoroarsenate, 4.065 parts of diphenyl sulfide and 0.2 part of copper benzoate was heated with stirring at a temperature of 120°-125° C. for 3 hours. The mixture was then poured while it was hot into a container whereupon the product crystallized. The product was extracted three times with diethylether and then air dried. There was obtained a 97% yield of triphenylsulfonium hexafluoroarsenate. The triphenylsulfonium hexafluoroarsenate product had a melting point of 195°-197° C. after it was further recrystallized from 95% ethanol.
