光/过渡金属协同催化体系已成为现代有机合成的重要研究方向. 近年来, 以地球丰产金属镍为催化中心、结合光催化的协同催化体系取得了突破性进展. 通过光化学过程, 该体系可高效转化多种烷基自由基前体, 反应条件温和, 在选择性构建C(sp2)—C(sp3)键方面展现出了显著优势. 光催化产生烷基自由基物种与镍催化C(sp2)—C(sp3)键构建的协同作用机制, 不仅拓展了交叉偶联反应的底物适用范围, 还为将大宗化学品转化为高附加值精细化学品开辟了新途径. 本综述梳理了该领域的研究进展, 重点关注烷基自由基前体的多样性来源, 并简要阐释了相关催化机理.

The photoredox/transition metal dual catalysis system has emerged as a pivotal research direction in modern organic synthesis. Recent breakthroughs have been achieved in dual catalytic systems centered on earth-abundant nickel and integrated with photoredox catalysis. This system efficiently converts diverse alkyl radicals precursors through photochemical processes under mild reaction conditions and demonstrates remarkable advantages in the selective construction of C(sp2)—C(sp3) bonds. Notably, the synergistic mechanism between photocatalytic generation of alkyl radical species and nickel-catalyzed C(sp2)—C(sp3) cross-coupling not only expands the substrate scope of cross-coupling reactions, but also unlocks novel pathways for the conversion of bulk chemicals into high-value-added fine chemicals. This review summarizes the research progress in this field, highlighting the diverse sources of alkyl radical precursors and discussing key catalytic mechanisms.
