A new and efficient nickel‐based protocol for the N‐arylation of indoles and carbazoles with aromaticchlorides, 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.
ureas, and cyclic imides using heteroaryl aryl ethers. The reaction involves the covalent bond-exchange reaction of N–CO and HetAr–O bonds without using metal bases and exhibits a broad applicability, giving diverse C–N-linked bi(heteroaryl)s containingfive- and six-membered heteroarenes. The N-heteroarylation of N–H azoles/azolones and pyridone proceeds at higher reaction temperatures.
