<i>N</i>,<i>O</i>-Bidentate ligand-tunable copper(<scp>ii</scp>) complexes as a catalyst for Chan–Lam coupling reactions of arylboronic acids with 1<i>H</i>-imidazole derivatives

Abstract

An efficient procedure for Chan-Lam coupling reactions of arylboronic acids with 1H-imidazole derivatives using N,O-bidentate ligand-tunable copper(ii) complexes as a catalyst under base-free conditions has been developed. This protocol features mild reaction conditions, high yields and compatibility with different functional groups, providing a direct and facile strategy for the construction of C-N bonds and synthesis of heterocyclic compounds.
