A convenient Ni(II)‐catalyzed C−C and C−N cascade coupling reaction was developed to directly access various 2,4‐disubstituted imidazoles. The reaction scope covers a variety of aryl and aliphatic substitutions, which demonstrate moderate‐to‐excellent yields. The tolerance of halogen and N‐containing heterocyclic groups demonstrates the versatility of this method for further synthetic explorations
开发了一种方便的Ni(II)催化的C-C和C-N级联偶联反应,可直接使用各种2,4-二取代的咪唑。反应范围涵盖了各种芳基和脂肪族取代基,显示出中等至优异的收率。卤素和公差Ñ含杂环基团的演示此方法作进一步的合成探索的多功能性。
