Nickel-catalyzed cross-coupling reactions of unactivated tertiary alkyl nucleophiles and aryl bromides have been developed using -heterocyclic carbene ligands. These processes are reviewed alongside earlier attempts to employ unactivated tertiary alkyl nucleophiles in cross-coupling reactions. Potential mechanisms for the transformations, and future challenges in this field are discussed.
利用N-杂环卡宾配体,已开发出镍催化的未活化叔烷基亲核试剂与芳基溴的交叉偶联反应。本文在回顾早期在交叉偶联反应中使用未活化叔烷基亲核试剂尝试的同时,对这些反应过程进行了综述。讨论了这些转化反应的潜在机理以及该领域未来面临的挑战。
