PREPARING AN UNSATURATED CARBOXYLIC ACID SALT FROM AN ALKENE AND CARBON DIOXIDE USING A COVALENTLY IMMOBILIZED TRANSITION METAL COMPLEX

摘要

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 and releasing the α,β-ethylenically unsaturated carboxylic acid salt with a base, wherein the carboxylation catalyst comprises a transition metal complex that is covalently immobilized on a solid support. The crude reaction product can be processed with little effort to obtain the carboxylic acid derivative at a purity level suitable for further processing into sanitary products.
