Abstract: The present invention relates to a catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt, comprising contacting an alkene and carbon dioxide with a carboxylation catalyst being a transition metal complex, an alkoxide, and an organic solvent, to obtain an α,β-ethylenically unsaturated carboxylic acid salt, the organic solvent being incompletely miscible with water at a pressure of 1 bar at at least one temperature T and selected from amides and ureas, T being a temperature in the range from 10° C. to 90° C.

Abstract: A catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt from an alkene, carbon dioxide and an alkoxide having a secondary or tertiary carbon atom directly bound to a [O—] group is described. The alcohol byproduct is distilled off after an intermediate phase separation. This provides pure β,β-ethylenically unsaturated carboxylic acid salt at minimum effort.
