Abstract In the presence of catalytic amounts of trityl chloride or trimethylsilyl chloride and tin(II) chloride, ketene dithioacetals smoothly react with allyl methyl ethers or α,β-unsaturated orthoesters to afford the corresponding allyl or alkoxycarbonylethyl substituted ketene dithioacetals in good yields.
