Abstract
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.
