Abstract: Catalytic 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, the carboxylation catalyst being a transition metal complex, which comprises a structurally constrained bidentate P,X ligand, wherein X is selected from the group consisting of P, N, O, and carbene, the P and X atom are separated by 2 to 4 bridging atoms, and wherein the bridging atoms are part of at least one 5- to 7-membered cyclic substructure. A further catalytic processes for preparing α,βethylenically unsaturated carboxylic acid derivatives from CO2 and an alkene is provided.

Abstract: In a process for preparing an alkalimetalor alkaline earth metal salt of an
α,β -ethylenically unsaturated carboxylic acid, a)a transition metal-alkene complex is reacted with CO
2 to give a metallalactone, b)the metallalactone is reacted with a base to give an adduct of the alkalimetal or alkaline earth metal salt of the
α,β -ethylenically unsaturated carboxylic acid with the transition metal complex, and c)the adduct is reacted with an alkene to release the alkalimetalor alkaline earth metalsalt of the
α,β -ethylenically unsaturated carboxylic acid and regenerate the transition metal-alkene complex. The baseis selected from alkalimetal or alkaline earth metal hydroxides and alkali metal or alkaline earth metal superbases.The alkene is, for example, ethene. The transition metal complex comprises, for example, nickel and a bidentate P,P, P,N, P,O or P,carbene ligand, such as 1,2-bis(di-
tert -butylphosphino)ethane.
