Nonetheless, such catalysis typically requires high-energy near-ultraviolet (NUV) or blue (380–450 nm) light. In contrast, the use of lower-energy light (>520 nm) in excited-state Pd catalysis remains largely unexplored. Herein, we report a low-energy light-driven excited-state Pd-catalyzed cross-coupling of pyridine N-oxides with unactivated alkyl bromides. Mechanistic studies reveal the formation of a Pd(0)–pyridine N-oxide complex that absorbs low-energy light.
