Chelation‐Assisted C−N Cross‐Coupling between Picolinamides and Aryl Boronic Acids under Nickel Catalysis

Abstract

Abstract A nickel‐catalyzed C−N cross‐coupling between picolinamides and aryl boronic acids was developed. It was promoted by the chelation assistance of picolinyl group without the use of ligands. The reaction proceeded under simple and mild conditions. It was applicable to various picolinamides as well as aryl boronic acids, providing the unsymmetrical N ‐aryl tertiary amides in moderate to good yields.
