  No pressure: The oxidation of aromatic CH bonds at room temperature was realized through a copper‐catalyzed “oxygenase‐type” oxidation of arenes and heteroarenes in the presence of air (see scheme). The reaction involves an oxygen‐atom transfer from O2 in the air onto the substrates.

  无压力：室温下，芳烃CH键的氧化是通过在空气存在下，铜催化的芳烃和杂芳烃的“加氧酶型”氧化实现的（请参见方案）。该反应涉及氧原子从空气中的O 2转移到基质上。

  Here, we report the method for copper-catalyzed N-arylation of diverse oxadiazolones by diaryliodonium salts under mild conditions in high yields (up to 92%) using available CuI as a catalyst. The developed method allows utilizing both symmetric and unsymmetric diaryliodonium salts bearing auxiliary groups such as 2,4,6-trimethoxyphenyl (TMP). We found that the steric effects in aryl moieties determined

  在这里，我们报告了使用可用的 CuI 作为催化剂在温和条件下以高产率（高达 92%）通过二芳基碘盐对不同恶二唑酮进行铜催化 N-芳基化的方法。所开发的方法允许使用带有辅助基团（例如 2,4,6-三甲氧基苯基 (TMP)）的对称和不对称二芳基碘盐。我们发现芳基部分的空间效应决定了 1,2,4-oxadiazol-5(4 H )-ones的 N-和 O-芳基化的化学选择性。甲基取代的二芳基碘盐显示出作为选择性芳基化试剂的巨大潜力。结构研究表明 1,2,4-oxadiazol-5(4 H)-对空间位阻二芳基碘鎓盐的芳基化的影响。还证明了所提出方法的合成应用对 1,3,4-恶二唑-2(3 H )-酮和 1,2,4-恶二唑-5-硫醇的选择性芳基化。
