Selective hydrogenation of tetrahydrofuryl acetylenic alcohols and acetates

Hydrogenation of tetrahydrofuryl acetylenic alcohols and acetates in the presence of a supported Pd-containing catalyst has been revealed to proceed at high rate and selectivity to compounds with internal triple bonds. Selectivity in olefin production is 98–99% at the complete conversion of the substrate, the activity of the catalyst varies from 1700 to 13,100 mol/g-at. Pd'h at 20°C and PH2=0.1 MPa.
