Room-temperature nickel-catalyzed amination of heteroaryl/aryl chlorides with Ni(II)–(σ-Aryl) complex as precatalyst

The room-temperature cross-coupling of heteroaryl and aryl chlorides with secondary cyclic amines can be effected using Ni(II)-(σ-aryl) complex as pre-catalyst. Some useful aromatic and heteroaromatic amine derivatives were readily synthesized in moderate to good yields in the presence of the Ni(II)-(σ-aryl) complex/NHC/KOtBu/toluene system.
