文摘

To find out the conditions for mild hydration of carbon-carbon triple bonds the hydration reactions of some terminal alkynes (FcCCH, PhCCH, C₅H₁₁CCH) on the Nafion film in supercritical carbon dioxide (sc-CO₂) were studied. The corresponding ketones were prepared in excellent yields. The hydration of 1-heptyne is accompanied by the isomerization of the terminal carbon-carbon triple bond into the internal one under acidic heterogeneous catalysis.
