A NEW PREPARATIVE METHOD FOR 1,3-DICARBONYL COMPOUNDS BY THE REGIOSELECTIVE OXIDATION OF α,β-UNSATURATED CARBONYL COMPOUNDS, CATALYZED BY PdCl2 USING HYDROGENPEROXIDES AS THE REOXIDANT OF Pd0

Article abstract of DOI:10.1246/cl.1980.257

α,β-Unsaturated esters and ketones are oxidized regioselectively to give β-keto esters and 1,3-diketones in good yields in aqueous acetic acid using Na2PdCl4 as the catalyst and t-butyl hydroperoxide or hydrogen peroxide as the reoxidant of Pd⁰.
