Abstract (en)

[origin: WO2013098772A1] In a process for preparing an alkalimetalor alkaline earth metal salt of an alpha,beta-ethylenically unsaturated carboxylic acid, a)a transition metal-alkene complex is reacted with CO2 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 alpha,beta-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 alpha,beta-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.
