Cobalt‐Catalyzed Suzuki Biaryl Coupling of Aryl Halides

Readily accessed cobalt pre‐catalysts with N‐heterocyclic carbene ligands catalyze the Suzuki cross‐coupling of aryl chlorides and bromides with alkyllithium‐activated arylboronic pinacolate esters. Preliminary mechanistic studies indicate that the cobalt species is reduced to Co0 during the reactio...

Summary:Readily accessed cobalt pre‐catalysts with N‐heterocyclic carbene ligands catalyze the Suzuki cross‐coupling of aryl chlorides and bromides with alkyllithium‐activated arylboronic pinacolate esters. Preliminary mechanistic studies indicate that the cobalt species is reduced to Co0 during the reaction. Einfache Cobaltkomplexe mit N‐heterocyclischen Carbenliganden katalysieren Suzuki‐Kreuzkupplungen mit Arylchloriden und ‐bromiden.
