1-[α-(Phenylthio)benzyl]- and 1-[(4-methylphenyl)(phenylthio)-methyl]benzotriazole, readily available from benzotriazole, an aldehyde and thiophenol, react with a variety of active aromatic compounds under mild conditions to give the thioalkylation products in moderate to good yields.

phosphite for the formation of thionium ions from aldehydes and thiophenols. These reactive species subsequently undergo reaction with in situ generated phenol, resulting in the synthesis of diarylmethyl thioethers. It was demonstrated that the addition of external phenol in the reaction produced unsymmetrical gem-diarylmethyl thioethers in good yields.

The cleavage of sulfidic C–S bonds under visible-light irradiation was harnessed to generate carbocations under neutral conditions and synthesize valuable di- and triarylalkanes as well as benzyl amines. To this end, photoredox catalysis and direct photoinduced C–S bondcleavage are used as complementary approaches and participate in the versatility of the general strategy.
