Abstract: The process comprises reacting 2-, 3- or 4-pentenenitrile or mixtures thereof with carbon monoxide and a hydroxyl compound in the presence of a catalyst system comprising (i) a palladium(II) compound, (ii) a bidentate diphosphine ligand and (iii) an anion source. Novel catalyst systems containing diphosphine ligands of the bis(phosphinomethyl)amine type are also described.
