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.
thioacetals to give the corresponding γ-ketosulfides in good yields with high stereoselectivity. In a similar manner, γ-ketosulfides are obtained in good yields by the one pot reaction directly fromketones and thioacetals via tin(II) enolates.
