    摘要: The present invention provides aqueous catalyst solutions useful for oxidation of olefins to carbonyl products, comprising a palladium catalyst, a polyoxoacid or polyoxoanion oxidant comprising vanadium, and chloride ions. 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. The present invention also provides a process for the oxidation of palladium(0) to palladium(II) comprising contacting the palladium(0) with an aqueous solution comprising chloride ions and a polyoxoacid or polyoxoanion oxidant comprising vanadium.
