In supercritical carbon dioxide, it is necessary to ald an excess of alcohol as co-solvent to facilitate palladium-catalyzed dicarbonylation of terminal alkynes and the results of the palladium- catalyzed dicarbonylation of terminal alkynes in supercritical carbon dioxide is different from those in convention organic solvent to some extent.
