Abstract: Copper-catalyzed C(sp3)-C(sp3) cross-coupling reactions represent a vital approach for constructing saturated aliphatic frameworks. However, these reactions face significant challenges, including high activation energy barriers, undesirable side reactions involving alkyl radicals, and difficulties in controlling stereoselectivity. In recent years, researchers have developed a range of efficient strategies to overcome these obstacles. This review systematically summarizes the latest progress in this field, with a focus on reaction mechanisms, selectivity regulation, and synthetic applications, and offers perspectives on future directions.
