| 摘 要： | One-pot hydroiodination and deconjugation of 5-aryloxy(or thiophenyl)-3-pentyn-2-one with a reagent system of sodium iodide/trimethylsilyl chloride/water in acetonitrile at 25℃ have been described.The plasuible mechanism was discussed.The reaction provided a simple and useful method for the preparation of (Z)-β-substituted β，γ-enones and (Z)-β-substituted α，β-unsaturated ketones.

| Abstract: | One‐pot hydroiodination and deconjugation of 5‐aryloxy (or thiophenyl) ?3‐pentyn‐2‐one with a reagent system of sodium iodide/trimethylsilyl chloride/water in acetonitrile at 25 °C have been described. The plausible mechanism was discussed. The reaction provided a simple and useful method for the preparation of (Z) ‐β‐substituted β, γ‐enones and (Z) ‐β‐substituted α, β‐unsaturated ketones. |
