Abstract
Process for the carbonylation of olefins with CO in the presence of water, an alcohol and/or a carboxylic acid in the presence of a catalyst composition based on (a) a Pd compound, (b) a protonic acid, and (c) a phosphine PR.sup.1 R.sup.2 R.sup.3 in which R.sup.1 is a heterocyclic ring having 5-6 atoms and containing .gtoreq.1 hetero N atom and R.sup.2 and R.sup.3 are R.sup.1 or an aryl group.
Claims20
A process for the carbonylation of an olefinically unsaturated compound which comprises reacting said olefinically unsaturated compound with carbon monoxide and a reactant selected from the group consisting of water, an alcohol, a carboxylic acid and mixtures thereof in the presence of a catalyst composition comprising:
- (a) a palladium compound,
- (b) a protonic acid, and
- (c) an organic phosphine of the general formula I ##STR2## wherein R.sup.1 represents a heterocyclic ring having 5 or 6 carbon atoms in the ring which contains at least one hetero nitrogen atom in the ring and wherein each of R.sup.2 and R.sup.3 has the same meaning as R.sup.1 or represents an aryl group.
