    Abstract: Solid .pi.-allyl complex catalysts comprising:(A) A palladium source;(B) A monotertiary phosphine electron donor ligand;(C) A combination of a reducing agent capable of reducing the palladium source to an oxidation state of less than 2 and a Lewis acid capable of forming a coordination bond with palladium; and(D) An acidic, solid, silica-based support material, are useful in the codimerization of a conjugated diene and a monoene. Preferably, the catalyst is activated by the additional presence of a conjugated diene. In a preferred embodiment, the solid .pi.-allyl palladium complex catalyst prepared from palladium acetylacetonate, triphenylphosphine, diethylaluminum chloride and a calcined silica-alumina support having a separate, distinct alumina phase is useful in the selective codimerization of 1,3-butadiene and ethylene to form trans-1,4-hexadiene.

    Abstract: The present invention relates to a process for producing an organic acid or its derivatives, which comprises oxidation of a hydrocarbon substrate in the presence of a homogeneous MC-type catalyst and an oxidant. In particular, the present invention relates to a process comprising oxidation of a hydrocarbon substrate in the presence of a homogeneous MC-type catalyst selected from Co/Br, Mn/Br, Co/Mn/Br and Co/Mn/M/Br and an O2/CO2 mixed gas oxidant where the partial pressure of O2 is controlled to 30-40%, thereby improving the oxidation rate, the conversion, the selectivity and the yield even under milder conditions. Especially, the present invention remarkably reduces down to a negligible level the production of color impurities and other impurities such as 4-CBA and p-toluic acid, which had been conventionally removed by hydrogenation reduction. Further, the loss in acetic acid solvent due to combustion can also be drastically decreased using the method of the present invention.
