Title:

HYDROGENATION CATALYST AND PROCESS FOR PRODUCTION OF ALKENES

Document Type and Number:

WIPO Patent Application WO/2003/068391

Kind Code:

A1

Abstract:

The conversion of an internal alkyne into a cis-alkene or that of a terminal alkyne into a terminal alkene can be carried out by conducting partial hydrogenation of an alkyne as the substrate with a catalytic amount of [1,2-bis(diphenyl- phosphino)propane]palladium chloride in a mixed solvent consisting of DMF and an alcohol in the presence of potassium t-butoxide or sodium borohydride and in the presence of hydrogen.
