Transition-metal-catalyzed cross-coupling chemistry can be regarded as one of the most powerful protocols to construct carbon-carbon bonds. While the field is still dominated by palladium catalysis, there is an increasing interest to develop protocols that utilize cheaper and more sustainable metal sources. Herein, we report a selective, practical, and fast iron-based cross-coupling reaction that enables
过渡金属催化的交叉偶联化学可被视为构建碳-碳键的最有效方法之一。尽管该领域仍以钯催化为主,但人们越来越有兴趣开发利用更便宜,更可持续的金属资源的方案。在本文中,我们报告了选择性,实用,快速的铁基交叉偶联反应,该反应能够形成Csp-Csp3和Csp2-Csp3键。在伸缩流动过程中,该反应可与格氏试剂合成结合。而且,流动允许避免使用支持配体而不会损害反应选择性。
