Arylbis(arylthio)sulfonium ions (ArS(ArSSAr)+), which were generated and accumulated by the low-temperature electrolysis of diaryl disulfide (ArSSAr), were found to serve as ArS+ equivalent in electrophilic substitution reactions of aromatic compounds, enolizable ketones, enol acetates, ketene silyl acetals and allylsilanes to give the corresponding arylthiolated products.
通过低温电解二芳基二硫化物(ArSSAr)生成和积累的芳基双(芳硫基)s离子(ArS(ArSSAr)+)在芳族化合物(可烯醇化的酮)的亲电取代反应中可作为ArS +等效物,烯醇式乙酸酯,乙烯酮甲硅烷基缩醛和烯丙基硅烷,得到相应的芳基硫醇化产物。
