    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 α,β-ethylenically unsaturated carboxylic acid salt at minimum effort.
