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.

activities by interacting with proteins and nucleic acids. Then, synthesis of such compounds is critical for the development of drugs. Unsymmetric HetAr-X-HetAr′ compounds were efficiently synthesized by rhodium-catalyzed heteroaryl exchangereactions, which involved equilibrium control by judicious design of organic heteroaryl reagents. This method allows synthesis of unsymmetric HetAr–O–HetAr′, HetAr–S–HetAr′
