Survey of the aryl bromides 4 and the 4‐alkyl‐1,4‐dihydropyridines 1 that can participate in the nickel‐catalyzed cross‐coupling process enabled by the photochemical activity of 1. Reactions performed on a 0.5 mmol scale using 1.5 equiv of 1 and an irradiance of 50 mW cm⁻². Yields refer to isolated products. [a] The NMR yield is given, since the compound was isolated together with 10 % of a byproduct. [b] Reaction time 72 hours. [c] 0.1 mmol scale reaction performed over 16 hours (average of two runs).
