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.
