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-nitrophenyl)methanone as the major products, respectively.
通过在三氟乙酸中用Oxone作为氧化剂处理芳烃炔烃,合成了多种1,2-二芳基二酮,产率在15%到90%之间。对1-硝基-2-(苯乙炔)苯和2,4′-(乙炔-1,2-二基)双(硝基苯)的氧化反应分别产生了1-苯甲酰苯并[c]异噁唑-3(1H)-酮和苯并[c]异噁唑-3-基(4-硝基苯基)甲酮作为主要产物。
