Hydrocarbonylation of methyl acrylate with CO and H<SUB>2</SUB>O forms dimethyl 4-oxopimelate in 94% yield based on H<SUB>2</SUB>O, the Co<SUB>2</SUB>(CO)<SUB>8</SUB>-1,2-bis(diphenylphosphino)ethane (diphos) catalyst system being used as in the case of ethylene or propylene. Increasing temperature tends to promote the dimerization and/or hydrodimerization of methyl acrylate to give 1,3-bis(methoxycarbonyl)-1-butene and/or dimethyl 2-methylglutarate. Effects of CO pressure and H<SUB>2</SUB>O concentration on the hydrocarbonylation and dimerization were examined at 135 and 165 °C. Catalytically active intermediates for the hydrocarbonylation take part in the dimerization of methyl acrylate.
