    摘要: A process for the manufacture of resorcinol is described which relies upon the intermediacy of a .alpha.,.beta.-unsaturated ketone which can be reacted with a hydroxy moiety-containing compound to obtain a resorcinol precursor which is subsequently converted to resorcinol. In a specific embodiment, 2-cyclohexenone is reacted with water to obtain 3-hydroxycyclohexanone which is dehydrogenated to resorcinol. In another embodiment, 2-cyclohexenone is oxidized to cyclohexane-1,3-dione which is dehydragenated obtain resorcinol.

    摘要: The additional of redox-active metal components and ligands, alternatively or simultaneously, results in increased conversion and selectivity in the palladium-catalyzed 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 by-product formation. The use of redox-active metal components and/or ligands makes the palladium-polyoxoanion catalyst system industrially practicable.
