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.
