ABSTRACT:
Diphosphines having at least one heterocyclic substituent that includes at least one oxygen, sulphur, or nitrogen atom in a five or six membered ring are useful components in palladium catalyst compositions which have been used to polymerize carbon monoxide and olefinically unsaturated compounds. Remaining substituents, if any, are carbocyclic hydrocarbon groups such as phenyls which are preferably substituted with polar groups in a ring position ortho to the phosphorus. The phosphorus atoms in the diphosphine are connected by a bridging group that contains at least one carbon atom.
