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.
