    摘要: The hexene-1,6-dioic acids, e.g., hex-3-ene-1,6-dioic acid, are prepared by reacting carbon monoxide and water with at least one diacyloxylated butene, in the presence of a catalytically effective amount of palladium and at least one quaternary onium chloride of one of the Group VB elements nitrogen or phosphorus, such element being tetracoordinated via carbon atoms and with the proviso that such nitrogen atom may be coordinated to two pentavalent phosphorus atoms.
