T 1546 A B S T R A C T CARBONYLATION PROCESS AND CATALYST COMPOSITION A process for the carbonylation of an olefinically or acetylenically unsaturated compound with carbon monoxide in the presence of a nucleophilic compound having a removable hydrogen atom and a catalyst system comprising a) a source of palladium, b) a phosphine of general formula PR1R2R3, wherein R1, R2 and R3 independently represent an optionally substituted alkyl, cycloalkyl, aryl or N-heterocyclic group, and c) a source of anions being the conjugated base of an acid having a pKa < 3, characterized in that the reaction medium at least initially is a multi-phase liquid reaction medium, and that the catalyst system comprises a component b) or c) having an amphiphatic structure, and catalyst compositions particularly suitable for said process.
