CN Coupling of Indoles and Carbazoles with Aromatic Chlorides Catalyzed by a Single‐Component NHC‐Nickel(0) Precursor

Abstract A new and efficient nickel‐based protocol for the N ‐arylation of indoles and carbazoles with aromatic chlorides, the least expensive of the aryl halides, is described. The procedure provides selectively N ‐(hetero)arylation products in good to high yields, in short reaction times and without adding an excess of ligands. magnified image
