An efficient, economic, and air-promoted metal-free method for direct arylation of benzoquinone with phenylhydrazines was developed. This approach leads to the formation of corresponding [1,1′-biphenyl]-2,5-dione derivatives as biological and pharmaceutical materials of interest in good yields, under mild reaction conditions, and at ambient temperature.
开发了一种高效、经济、并且在空气中促进的无金属直接芳基化苯醌与苯基肼的方法。这种方法在温和的反应条件和室温下,以良好的产率形成对应的[1,1'-联苯]-2,5-二酮衍生物,作为生物和药用材料感兴趣。
