ABSTRACT:
Difunctional butenes are linearly dicarbonylated into 3-hexene-1,6-dioic acid or alkyl diesters thereof, well suited for the ultimate production of, e.g., adipic acid, by reacting such difunctional butene with carbon monoxide and, if appropriate, an alcohol, at an elevated temperature under superatmospheric pressure, in the presence of at least one source of hydrogen chloride and a catalytically effective amount of palladium, at least a portion of which palladium being in the zero oxidation state, as well as a quaternary onium chloride of nitrogen or phosphorus, the nitrogen or phosphorus atom being tetracoordinated to carbon atoms, with the proviso that the nitrogen atom may be coordinated to two pentavalent phosphorus atoms.
