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)
分别用甲硅烷基亲核试剂(三乙基硅烷、烯丙基三甲基硅烷、三甲基氰化氰化物等)处理后,分别由γ-、δ-和ε-甲硅烷氧基羰基化合物以高产率通过一锅法制备五七元环醚。存在催化量的六氯锑酸三苯甲基酯,或五氯化锑、氯三甲基硅烷和碘化锡 (II) 的催化剂体系。
