This work emphasizes the synthesis of substituted vinyl arenes by reductive coupling of aryl halides with vinyl bromides under mild and easy‐to‐operate nickel‐catalyzed reaction conditions. A broad range of aryl halides, including heteroaromatics, and vinyl bromides were employed to yielding products in moderate to excellent yields with high functional‐group tolerance. The nickel‐catalytic system displays
这项工作强调了在温和且易于操作的镍催化反应条件下,通过芳基卤化物与乙烯基溴的还原偶联来合成取代的乙烯基芳烃。广泛使用的芳基卤化物,包括杂芳族化合物和乙烯基溴化物,以中等至优异的收率生产了具有高官能团耐受性的产品。镍催化系统在两个C(sp 2)-卤化物偶合体之间显示出良好的化学选择性,从而证明了不同于其他逐步方案的机理途径。
