Catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt, wherein an alkene and carbon dioxide are reacted in the presence of a carboxylation catalyst and in the presence of a specific aryloxide to obtain the α,β-ethylenically unsaturated carboxylic acid salt, the carboxylation catalyst being a transition metal complex. The process allows for efficient preparation of α,β-ethylenically unsaturated carboxylic acid derivatives from CO2 and an alkene. |

1. A catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt, the catalytic process comprising reacting an alkene and carbon dioxide in the presence of a carboxylation catalyst and an aryloxide to obtain the α,β-ethylenically unsaturated carboxylic acid salt,
wherein: the carboxylation catalyst is being a transition metal complex; the aryloxide corresponds to formula (I): R is selected from the group consisting of F, Cl, Br, I, a C1-C16-alkyl, and a C3-C16-cycloalkyl, and two vicinal R groups may constitute a C3-C5-hydrocarbylene bridge that is optionally substituted by one to four substituents which are independently selected from the group consisting of F, Cl, Br, I, a C1-C16-alkyl, and a C3-C16-cycloalkyl; n is an integer selected from 1 to 5; and at most two R groups are F. |
