Abstract

A process comprising subjecting at least one compound containing at least one carbon--carbon double bond or at least one carbon--carbon triple bond, hydrogen and carbon monoxide, to a hydrocarbonylation reaction in supercritical carbon dioxide, in the presence of a Group VIII transition metal catalyst precursor, and a phosphite ligand.
