具有 N-杂环卡宾配体的易于获得的钴预催化剂可催化芳基氯和芳基溴化物与烷基锂活化的芳基硼频那醇酯的 Suzuki 交叉偶联。初步机理研究表明,钴物质在反应过程中被还原为 Co0。
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 Co0during the reaction.
