Progress in Ni/photoredox dual catalysis has enabled the construction of C(sp³)-hybridized centers under extremely mild reaction conditions in the presence of diverse functional groups. These strategies, however, are mainly restricted to the assembly of one C–C or C–heteroatom linkage because of the competitive two-component reactions and facile β-hydride elimination from alkylmetal complexes. Recently, photoinduced nickel-catalyzed 1,2-difunctionalizations of alkenes and alkynes have attracted extensive research efforts because they allow the construction of two sequential chemical bonds from inexpensive starting materials in one pot. Herein, we explore recent advances, state the current challenges, and discuss perspectives on the design of new catalytic systems.

Ni/光氧化还原双重催化的进展使得在存在不同官能团的情况下在极其温和的反应条件下构建C(sp ³ )杂化中心成为可能。然而，由于竞争性双组分反应和容易从烷基金属配合物中消除β-氢化物，这些策略主要限于一个C-C或C-杂原子键的组装。最近，光诱导镍催化的烯烃和炔烃的 1,2-双官能化吸引了广泛的研究工作，因为它们允许在一锅中用廉价的起始材料构建两个连续的化学键。在此，我们探讨最新进展，陈述当前挑战，并讨论新催化系统设计的观点。
