Prized for their ability to streamline organic synthesis, cross-couplings have become fundamental reactions in many settings. In photoinduced cross-coupling chemistry, metallaphotoredox catalysis remains state-of-the-art, typically featuring a dual catalytic partnership of a chromophoric compound and an organometallic complex. However, designing such a highly variable, multicomponent linchpin ranks among the most challenging endeavors in synthetic practice since identifying the optimal combination often requires considerable experimentation. Herein, we outline a simple and general solution to this problem by devising a photoactive ligand that could complex with a series of transition metals and serve as “two-in-one” metallaphotoredox catalysts. Our bifunctional system is compatible with a diverse pool of nucleophilic and electrophilic coupling partners and highly enabling in visible-light-driven C–C and C–X bond formations. We envision that this nonclassical toolkit would open chemical space for novel coupling reactivities and inspiring future research efforts in a broad scientific community.

交叉偶联因其简化有机合成的能力而备受赞誉，已成为许多环境中的基本反应。在光诱导交叉偶联化学中，金属光氧化还原催化仍然是最先进的，通常具有发色化合物和有机金属配合物的双重催化伙伴关系。然而，设计这种高度可变的多组分关键销是合成实践中最具挑战性的工作之一，因为确定最佳组合通常需要大量的实验。在这里，我们通过设计一种可以与一系列过渡金属络合并用作“二合一”金属光氧化还原催化剂的光活性配体，概述了该问题的简单而通用的解决方案。我们的双功能系统与多种亲核和亲电偶联伙伴池兼容，并且在可见光驱动的 C-C 和 C-X 键形成中具有很高的能力。我们设想这种非经典工具包将为新的耦合反应打开化学空间，并激发广泛科学界的未来研究工作。
