Novel generation of phenylsulfenium ion and aromatic phenylthiolation. Reactions of hydrazoic acid, alkyl azides and hydroxylamine derivatives with alkyl phenyl sulfides in the presence of both trifluoromethanesulfonic acid and trifluoroacetic acid
Reactions of hydrazoic acid and alkyl azides with alkyl phenyl sulfides in the presence of both trifluoromethanesulfonic acid and trifluoroaceticacid gave 4-alkylthiophenyl phenyl sulfides in high yields via a phenylsulfenium ion.
