Five–seven membered cyclic ethers are prepared by one-pot procedure in good yields from γ-, δ-, and e-siloxy carbonyl compounds, respectively, on treatment with silyl nucleophiles (triethylsilane, allyltrimethylsilane, trimethylsilyl cyanide, etc.) in the presence of a catalytic amount of trityl hexachloroantimonate, or a catalyst system of antimony pentachloride, chlorotrimethylsilane and tin (II)
