    摘要: The present invention provides aqueous catalyst solutions useful for oxidation of olefins to carbonyl products, comprising a palladium catalyst and a polyoxoacid or polyoxoanion oxidant comprising vanadium. It also provides processes for oxidation of olefins to carbonyl products, comprising contacting olefin with the aqueous catalyst solutions of the present invention. It also provides processes for oxidation of olefins to carbonyl products by dioxygen, comprising contacting olefin with the aqueous catalyst solutions of the present invention, and further comprising contacting dioxygen with the aqueous catalyst solutions. In certain aqueous catalyst solutions and related processes of the present invention, the solution has a hydrogen ion concentration greater than 0.10 mole per liter when essentially all of the oxidant is in its oxidized state. In other aqueous catalyst solution and related processes of the present invention, the solution is essentially free of sulfuric acid and sulfate ions.
