Oxidative Arylation Mediated by Naphthalene-1,8-diylbis(diphenylmethylium): Synthetic Route to Triarylsulfonium Salts

Dicationic species, naphthalene-1,8-diylbis(diphenylmethylium), successfully promoted oxidative arylation of the sulfur atom in (4-N,N-dialkylaminophenyl) phenyl sulfides with (4-N,N-dialkylaminopheny)silanes, affording triarylsulfonium salts in good yield.
