利用Pd/CeO 2纳米复合光催化剂，在可见光照射下，不使用任何氧化剂和促进剂，发展了一种简单、温和、绿色的合成不对称杂联芳基化合物的方法。该方法通过C单键C交叉偶联，可容许大量的供电子基团和吸电子基团。此外，我们以一种有效的方式获得了中等产率的产品。最后，提出了一个合理的机制。
A simple, mild and green approach has been developed for the synthesis of asymmetrical heterobiaryls under the irradiation of visible light without any oxidants and promoting reagents through using Pd/CeO2nanocomposite photocatalyst. This method can tolerate considerable functional groups such as electron-donating groups and electron-withdrawing groups through Csingle bondC cross-coupling. Moreover, we obtain the products with moderate yields in an efficient way. Finally, a plausible mechanism is proposed.
