ABSTRACT:
A triarylsulfonium salt is prepared in high yield and high purity by a two-step process involving a aryl Grignard reagent reacted with a diarylsulfoxide in a solvent which is a mixture of aliphatic and aromatic hydrocarbons, followed by a second step which is metathesis with ZMF.sub.6, where Z is a metal or metal-like anion, and M is antimony, arsenic or phosphorus, preferably employing an ammonium salt and carried out in a non-aqueous solvent.
