Process for preparing an α, β -ethylenically unsaturated carboxylic acid salt, comprising, reacting an alkene and carbon dioxide in the presence of a carboxylation catalyst to obtain a catalyst-coordinated carboxylated intermediate, treating the catalyst- coordinated carboxylated intermediate with a heterogeneous base, and releasing the α, β -ethylenically unsaturated carboxylic acid salt, wherein the heterogeneous base comprises an organic basic moiety that is immobilized on a solid support. The process avoids accumulation of the conjugate acid of the base in the reaction medium. |
