Arylation, vinylation, and alkynylation of electron-deficient arenes and heteroarenes have been achieved by chemoselective C–H zincation followed by copper-catalyzed coupling reactions using iodonium salts. This approach offers a direct and general access to a wide scope of (hetero)biaryls as well as alkenylated and alkynylated heteroarenes under mild conditions. It is particularly useful and valuable
电子不足的芳烃和杂芳烃的芳构化,乙烯基化和炔基化反应是通过化学选择性的C–H锌化反应,然后使用碘鎓盐在铜催化下进行偶联反应而实现的。这种方法可在温和条件下直接和通用地获得各种(杂)联芳基以及烯基化和炔基化的杂芳烃。如瞬态受体电位类香草素1(TRPV1)拮抗剂和血管紧张素II受体1型(AT1受体)拮抗剂的合成所证明的,它对于多种(杂)芳基化合物的快速模块化合成特别有用且有价值。
