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.
Claims11
A catalyst system for the carbonylation of olefinically or acetylenically unsaturated compounds by means of carbon monoxide and a nucleophilic compound, comprising
- (a) palladium,
- (b) a phosphine, and
- (c) a polyethylenimine.
A process for the carbonylation of olefinically or acetylenically unsaturated compounds by means of carbon monoxide and a nucleophilic compound, wherein a catalyst system comprising
- (a) palladium,
- (b) a phosphine, and
- (c) a nitrogen-containing polymer which is homogeneously dissolved or at least colloidally dispersed in the reaction mixture, with the exception of polyvinyl polymers having aromatic nitrogen-containing radicals on the polymer chain
- is used.
