Olefin Oxidation Catalyst System The addition of redox-active metal components and ligands, alternatively or simultaneously results in, increased conversion and selectivity in the palladiumcatalyzed oxidation of olefins to carbonyl products in the presence of polyoxoanions. In preferred modes heteropolyoxoanions and isopolyoxoanions containing tungsten, molybdenum and vanadium, individually or in combination, are described. The use of copper as the redox-active metal component shows reduced allylic reactivity. The elimination of chloride from the catalyst system provides substantial engineering advantages over the prior art, particularly the, reduction of corrosion and chloro-organic …
