A general method for a highly regioselective copper-catalyzed cross-coupling of two aromatic compounds using iodine as an oxidant has been developed. The reactions involve an initial iodination of one arene followed by arylation of the most acidic C-H bond of the other coupling component. Cross-coupling of electron-rich arenes, electron-poor arenes, and five- and six-membered heterocycles is possible
已经开发了一种使用碘作为氧化剂对两种芳香族化合物进行高度区域选择性的铜催化交叉偶联的通用方法。该反应涉及一种芳烃的初始碘化,然后是另一种偶联组分的酸性最强的 CH 键的芳基化。富电子芳烃、缺电子芳烃和五元和六元杂环的交叉偶联在许多组合中都是可能的。通常,使用 1/1.5 到 1/3 比率的耦合组分,这与通常使用大量过量芳烃之一的现有方法形成对比。常见的官能团如酯、酮、醛、醚、腈、硝基和胺具有良好的耐受性。
