By using a zerovalent, electron-rich ruthenium complex bearing a tetradentate phosphine ligand, a five-membered ruthenalactone was generated by oxidative cyclization of ethylene and CO2. This ruthenalactone underwent thermal, reversible β-H elimination to afford an acrylato(hydrido)ruthenium(II) complex, which liberated acrylate salt on treatment with a base. The reaction was successfully applied to the first ruthenium-catalyzed synthesis of an acrylate salt from ethylene and CO2. This study demonstrated the feasibility of the electron-rich ruthenium(0) complex as a catalyst in CO2-fixation chemistry.

Paragraph 0067, (2019/04/11)
Methods of producing α,β-unsaturated carboxylic acid salts are described. A method can include reacting an alkene and carbon dioxide with a composition that includes a carboxylation catalyst and an inorganic base in a protic solvent under reaction conditions suitable to produce an inorganic base salt of an α,β-unsaturated carboxylic acid.

A process for the preparation of bromo-substituted aromatic esters of α, β-unsaturated acids of the formula STR1 wherein n is 1 or 2, x=6'n, and R and R' are hydrogen or alkyl; comprises reacting a salt of α,β-unsaturated acid and an alkali with a bromo-substituted benzyl halide in an inert substantially water-immiscible solvent and in the presence of a phase-transfer catalyst.
