<p>In the process for reacting a mixture of 1,3-butadiene, carbon monoxide and a monoalkanol of the general formula ROH in which R is a straight or branched chain alkyl group of from 1 to about 12 carbon atoms in the presence of, as catalyst, a palladium-ligand complex which comprises (a) a member selected from the group consisting of zerovalent palladium, a palladium-containing composition which can provide zerovalent palladium under reaction conditions and palladium (II) salt, (b) a strong ligand consisting of tertiary phosphine having a pKa in water of not greater than about 6, and (c) a weak ligand consisting of tertiary phosphine having a pKa in water of greater than about 6, to provide alkyl nonadienoate ester, optionaliy containing at least one phenol promoter, and if desired, an alkoxide ion.</p> |
