development of a new method to use palladium catalysis to form functionalized aromatics: via the metathesis of covalent σ-bonds between Ar-X fragments. This transformation demonstrates the dynamic nature of palladium-based oxidative addition/reductive elimination and offers a straightforward approach to incorporate reactive functional groups into aryl halides through exchange reactions. The reaction has
我们描述了一种使用钯催化形成功能化芳烃的新方法的开发:通过 Ar-X 片段之间的共价 σ 键的复分解。这种转变证明了基于钯的氧化加成/还原消除的动态特性,并提供了一种通过交换反应将反应性官能团结合到芳基卤化物中的直接方法。该反应已被用于在不使用高能卤化或有毒试剂的情况下组装酰氯,而是通过芳基碘与其他酰氯的复分解。
