Versuchsvorschrift

The present invention is based on the discovery that higher yields of aromatic sulfonium salts including substituted derivatives thereof can be obtained at lower reaction temperatures and enhanced reaction rates by employing a copper salt catalyst in combination with the aryl iodonium salt and aryl sulfide or alkyl sulfide. A typical reaction, for example, would be the reaction between diphenyliodonium hexafluoroarsenate and diphenylsulfide in the presence of a copper benzoate catalyst to produce a 97% yield of triphenylsulfonium hexafluoroarsenate at 120° C. for three hours.
