ABSTRACT:
Process for the carbonylation of olefinically unsaturated compounds with carbon monoxide in the presence of a hydroxyl-group-containing compound, a palladium catalyst, an organic phosphine, an acid with a pKa value <2, with the exception of halogen acids and carboxylic acids as promoter, and a catlayst stabilizer selected from the group consisting of compounds of the general formula; ##STR1## wherein X represents an element of group Va with a valency greater than 3, selected from P. As or Sb, where Y represents an element of group VIa, selected from O, S or Se, and where either a, b and c are 0 or 1, where R.sub.4, R.sub.5 and R.sub.6 are the same or different and represent hydrocarbon groups, or a and b=0 and c=0 or 1 and R.sub.4 and R.sub.5 together with X form a heterocyclic group, or a, b and c=0 and R.sub.4, R.sub.5 R.sub.6 together with X form a heterocyclic group, compounds of the general formula: ##STR2## wherein R.sub.7 is a hydrocarbon group and where R.sub.8 and R.sub.9 are each the same or different and have the aforesaid meaning of R.sub.7 or together with N form a heterocyclic ring, or where R.sub.7 and R.sub.8 or R.sub.9 together with the residue ##STR3## form a heterocyclic ring such as a pyrrolidon or caprolactam ring and mixtures thereof.
