Abstract

2-aminopyridine 1-oxides are effective ligands for Cu-catalyzed amination of less reactive (hetero)aryl chlorides with aliphatic amines. A wide range of functionalized (hetero)aryl chlorides reacted with various primary and cyclic secondary amines to afford the desired products in good to excellent yields.
