A Cu-catalyzed C–O coupling of (hetero)arylchlorides with phenols at 120 °C on water was developed with a designed ligand, N-(9H-carbazol-9-yl)picolinamide (L2). This method features a good substrate scope (both electron-donating and electron-withdrawing), low catalyst/ligand loadings (down to 1 mol %), and excellent scalability and practicability.
使用设计的配体N -(9 H -咔唑-9-基)吡啶酰胺 ( L2 ),在 120 °C 的水中开发了(杂)芳基氯与苯酚的 Cu 催化 C-O 偶联。该方法具有良好的底物范围(供电子和吸电子)、低催化剂/配体负载量(低至1 mol%)以及优异的可扩展性和实用性。
