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 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.
