A triarylsulphonium salt is prepared in high yield and high purity by a two-step process involving a aryl Grignard reagent reacted with a diarylsulphoxide in a solvent which is a mixture of aliphatic and aromatic hydrocarbons, followed by a second step which is metathesis with ZMF₆, 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.
三芳基硫鎓盐是通过两步法制备的,第一步是芳基格氏试剂与二芳基环氧乙烷在脂肪烃和芳香烃的混合物溶剂中反应,第二步是与 ZMF₆(其中 Z 是金属或类金属阴离子,M 是锑、砷或磷,最好使用铵盐)在非水溶剂中进行偏析反应,从而制备出高产率和高纯度的三芳基硫鎓盐。
