A mild method for preparation of 1,4-diketone via the intermolecular coupling of substituted aryl β-ketoesters by use of cerium ambmonium nitrate in CH3CN/H2O has been reported. The procedure provided a convenient method for synthesis of 1,4-diketones in up to 92% yields and a powerful evidence of the oxidation mechanism by cerium ambmonium nitrate.

Key words: cross-coupling, β-ketoester, 1,4-diketone, cerium ammonium nitrate
