prepared via ethylthiomethylation reaction of aromatic compounds. These aromatic electrophilic substitutions were performed by in situ generation of the thionium ions by reacting trifluoroacetic anhydride and S-ethyl 2-(ethylsulfinyl)ethanethioate or ethyl 2-(ethylsulfinyl)acetate in the presence of Lewis acids. Some mechanistic features of these ethylthiomethylation reactions are also presented. α-Sulfanylated
