Catalyzed by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and sodium nitrite, the coupling reaction of 1,3-diarylpropynes and 1,3-dicarbonyl compounds using molecular oxygen as a terminal oxidant was developed. The reaction was promoted dramatically in

(Chemical Equation Presented) A highly efficient oxidative-coupling reaction between diarylpropargylic sp3 C-H and active methylenic sp3 C-H was achieved with DDQ as oxidant. The reaction afforded a direct method for the propargylation of 1,3-dicarbonyl compounds, thus providing a concise synthesis of the corresponding products.
