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 NiII 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.
