A regioselective green approach for the nickel(II)-catalyzed C–N cross-coupling between arylamines and pyrazoles through a photoredox process is reported. Moderate to good yield was observed for this reaction, performed in water under air at room temperature. This strategy provides a powerful tool for the green synthesis of pyrazole-containing bioactive molecules. In addition, a single-electron-transfer
据报道,通过光氧化还原过程,镍(II)催化的芳基胺和吡唑之间的C–N交叉偶联是一种区域选择性的绿色方法。对于该反应,在水中在室温下于空气中进行,观察到中等至良好的产率。该策略为绿色合成含吡唑的生物活性分子提供了强大的工具。此外,本报告提出了单电子转移机制。
