either twisted-amides or heteroaryl halides with alkyl halides, enabled by ball-milling, is herein described. The operationally simple nickel-catalyzed process has no requirement for inert atmosphere or dry solvents and delivers the corresponding acylated or heteroarylated products across a broad range of substrates. Key to negating the necessity of inert reaction conditions is the mechanical activation
本文描述了通过球磨实现的扭曲酰胺或杂芳基卤化物与烷基卤化物的交叉亲电子偶联。操作简单的镍催化工艺不需要惰性气氛或干燥溶剂,并且可以在各种基材上提供相应的酰化或杂芳基化产物。消除惰性反应条件必要性的关键是原料金属末端还原剂的机械活化:对于扭曲酰胺来说是锰,对于杂芳基卤化物来说是锌。
