α-Acetoxy sulfides can be conveniently prepared by the reaction of dithioacetals with mercuric acetate at ambient temperature. They react with allyltrimethylsilane, enol silyl ethers, and cyanotrimethylsilane in the presence of SnCl4 to afford butenyl sulfides, γ-keto sulfides and α-cyano sulfides, respectively.

Stable, crystalline α-(benzotriazolyl)methylphenyl thioethers (1), easily prepared from carbonyl compounds, thiophenol and benzotriazole, are convenient reagents for the phenylthiomethylation of trimethylsilyl cyanide, trimethylallylsilane, and trimethylsilyl enol ethers to afford the corresponding substituted thioethers and β-phenylthioalkylketones (3) in good yields.
