PROCESS FOR PREPARATION OF CYCLOPENTENONES IN SUPERCRITICAL FLUIDS

摘要

The present invention relates to a process for preparation of cyclopentenones using supercritical fluids as reaction solvent. Particularly, the present invention provides: i) a process for preparation of cyclopentenones by reacting acetylene compound with triple bond and olefin compound with double bond in carbon monoxide atmosphere in the presence of homogeneous metal catalyst using supercritical fluids as reaction solvent; and ii) a process for preparation of cyclopentenones by ring-closing reaction of enyne compound under carbon monoxide atmosphere in the presence of homogeneous metal catalyst using supercritical fluids as reaction solvent.
