to be effective ligands for the Cu-catalyzed amination of less reactive (hetero)aryl chlorides. A wide range of functionalized (hetero)aryl chlorides reacted with various aliphatic amines to afford the desired products in good to excellent yields under the catalyst of CuI/2-aminopyridine 1-oxides. Furthermore, the catalyst system worked well for the coupling of cyclic secondary amines and N-methyl benzylamine
发现一类2-氨基吡啶1-氧化物是用于铜反应性较低的(杂)芳基氯化物的铜催化胺化的有效配体。在CuI / 2-氨基吡啶1-氧化物的催化剂下,各种官能化的(杂)芳基氯化物与各种脂族胺反应,以良好或优异的收率提供所需的产物。此外,该催化剂体系对于环状仲胺和N-甲基苄基胺与(杂)芳基氯化物的偶联作用良好。
