Photoinduced Carbon−Heteroatom Cross‐Coupling Catalyzed by Nickel Naphthyridine Complexes

Abstract We describe versatile and practical light‐promoted C−N and C−O cross‐coupling reactions catalyzed by Ni II complexes supported by 2,7‐dimethyl‐1,8‐naphthyridine ligand. Using the same Ni catalyst and visible light irradiation, both C−O and C−N coupling reactivity was observed without additional photocatalysts. These results demonstrate that Ni naphthyridine complexes represent a versatile catalytic motif for photoredox nickel catalysis alternative to commonly used bipyridines or multidentate ligands.
