摘要
A variety of 1,2-diaryldiketones were synthesized in 15-90% yields by treatment of diarylacetylenes with Oxone as the oxidant in trifluoroacetic acid. Oxidation of 1-nitro-2-(phenylethynyl)benzene and 2,4'-(ethyne-1,2-diyl)bis(nitrobenzene) furnished 1-benzoylbenzo[c]isoxazol-3(1H)-one and benzo[c]isoxazol-3-yl(4-nitrophertyl)methanone as the major products, respectively.
