A continuous‐flow, visible light‐promoted method has been developed to overcome the limitations of Fe‐catalyzed Kumada‐Corriu cross‐couplings. A variety of strongly electron‐rich aryl chlorides, previously hardly reactive, could be efficiently coupled with aliphatic Grignard reagents at room temperature, in high yields and within a few minutes residence time, considerably enhancing the applicability of this Fe‐catalyzed reaction. The robustness of this protocol was demonstrated on the multi‐gram scale, providing the potential for future pharmaceutical application.
