Abstract
A catalyst system, which contains PA0 a) a source of a group VIII metal, and PA0 b) a phosphine of general formula: ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are independently selected from an optionally substituted aryl group and a group of general formula: ##STR2## wherein eachh of A, X, Y and Z is independently selected from a nitrogen atom, a CH group and a group of formula CR wherein R represents a hydroxyl group, an amino group, an amido group, a cyano group, an aryl group, an aryloxy group, a halogen atom, an optionally substituted hydrocarbyl group or an optionally substituted hydrocarbyloxy group, it also being possible for two adjacent CR groups to form a ring, provided that at least one of R.sup.1, R.sup.2 and R.sup.3 represents a group of formula (II) in which at least one of A and Z represents a group of formula CR; or an acid addition salt thereof. Also disclosed is the use of the catalyst system in the selective carbonylation of unsaturated hydrocarbons.
