A process for the carbonylation of ethylenically unsaturated compounds including vinyl esters and a process for the production of 3-hydroxy propanoate esters or acids. The process comprises reacting said compound with carbon monoxide in the presence of a source of hydroxyl groups and of a catalyst system. The catalyst system is obtainable by combining: (a) a metal of Group 8, 9 or 10 or a compound thereof: and (b) a bidentate ligand of general formula (I): X1(X2)- Q2 - A - R- B - Q1 - X3(X4).

L~invention concerne un procédé de carbonylation de composés à insaturations éthyléniques, y compris des esters de vinyle, et un procédé de fabrication d~acides ou d~esters 3-hydroxy propanoate. Le procédé comprend la mise en réaction dudit composé avec du monoxyde de carbone en présence d~une source de groupes hydroxyle et d~un système catalytique. Le système catalytique est obtenu par mélange de : (a) un métal du groupe 8, 9 ou 10 ou un composé dudit métal et de (b) un ligand bidentate de formule générale (I) : X1(X2)- Q2 - A - R- B - Q1 - X3(X4).
