general and effective CuI/N′,N′-diaryl-1H-pyrrole-2-carbohydrazide catalyst system was developed for the amination of aryliodides and bromides at room temperature with good chemoselectivity between −OH and −NH2 groups. Only 5 mol % of CuI and ligands was needed in this protocol to effect the amination of various arylbromides and aryliodides with a wide range of aliphatic and aryl amines (1.3 equiv)

C-N cross-coupling is one of the most valuable and widespread transformations in organic synthesis. Largely dominated by Pd- and Cu-based catalytic systems, it has proven to be a staple transformation for those in both academia and industry. The current study presents the development and mechanistic understanding of an electrochemically driven, Ni-catalyzed method for achieving this reaction of high
CN 交叉偶联是有机合成中最有价值和最广泛的转化之一。它主要由 Pd 和 Cu 基催化系统主导,已被证明是学术界和工业界人士的主要转变。目前的研究展示了一种电化学驱动的镍催化方法的发展和机理理解,以实现这种具有高度战略重要性的反应。通过一系列电化学、计算、动力学和经验实验,该反应的关键机制特征已被揭开,从而产生了适用于广泛芳基卤化物和胺亲核试剂的第二代条件,包括复杂的例子寡肽、药用杂环、天然产物和糖。
