| 摘 要： | The reaction of difluorodiiodomethane with alkynes (4a-e) in the presence of hydrogen peroxide afforded the corresponding β-iodo-α,β-unsaturated carboxylic acids.When propargylic alcohol was used as the substrate,β-iodo-α,β-unsaturated γ-butyrolactone (5f) was produced.The mechanism of the reaction was suggested.
