The merging of photoredox and transition‐metal catalysis has become one of the most attractive approaches for carbon–carbon bond formation. Such reactions require the use of two organo‐transition‐metal species, one of which acts as a photosensitizer and the other one as a cross‐coupling catalyst. We report herein an exogenous‐photosensitizer‐free photocatalytic process for the formation of carbon–carbon bonds by direct acceleration of the well‐known nickel‐catalyzed Negishi cross‐coupling that is based on the use of two naturally abundant metals. This finding will open new avenues in cross‐coupling chemistry that involve the direct visible‐light absorption of organometallic catalytic complexes.

不含外源光敏剂的光催化作用下可见光诱导的镍催化的Negishi交叉偶联

光氧化还原和过渡金属催化的合并已成为形成碳-碳键的最有吸引力的方法之一。此类反应需要使用两种有机过渡金属物种，其中一种用作光敏剂，另一种用作交叉偶联催化剂。我们在此报告了通过使用两种天然丰富金属的直接加速众所周知的镍催化的Negishi交叉偶联来形成碳-碳键的无外源光敏剂的光催化过程。这一发现将为交叉偶联化学开辟新途径，其中涉及有机金属催化配合物的直接可见光吸收。
