Cobalt-Catalyzed Cross-Coupling Reactions of Arylboronic Esters and Aryl Halides

An efficient cobalt catalyst system for the Suzuki–Miyaura cross-coupling reaction of arylboronic esters and aryl halides has been identified. In the presence of cobalt­(II)/terpyridine catalyst and potassium methoxide, a diverse array of (hetero)­biaryls have been prepared in moderate to excellent yields.
