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 Co during the reaction.
易于获得的带有 N-杂环卡宾配体的钴前催化剂可催化芳基氯代物和溴代物与烷基锂活化的芳基硼酸频哪醇酯的 Suzuki 交叉偶联反应。初步的机理研究表明,在反应过程中钴物种被还原为 Co。
