ABSTRACT:
The invention relates to a catalyst system for carbonylating olefinically or acetylenically unsaturated compounds with carbon monoxide and a nucleophile compound, containing (a) palladium; (b) a phosphine and (c) a polymer containing nitrogen which is soluble in the reaction mixture, with the exception of polyvinyl polymers with aromatic radicals containing nitrogen on the polymer chain. The invention also relates to a method for carbonylation in the presence of one such catalyst system.
