Synthesis of 2-Arylpyridines and 2-Arylbipyridines via Photoredox-Induced Meerwein Arylation with in Situ Diazotization of Anilines

We report herein a sustainable method for the preparation of 2-arylpyridines through C-H arylation of pyridines using in situ formed diazonium salts (from commercially available aromatic amines) in the presence of a photoredox catalyst under blue light-emitting diode (LED) irradiation. The reaction is tolerant to a wide range of functional groups (e.g., halogen, nitrile, formyl, acetyl, ester). Applications to the C-H bond arylation of bipyridine ligands is also presented.

New 4-pyridyl nonaflates as precursors for push-pull solvatochromic dyes

2,6-Disubstituted 4-pyridyl nonaflates including methyl, phenyl, 2-thienyl and 2-furyl groups were prepared by cyclocondensation reactions of the appropriate β-ketoenamides. Palladium-catalyzed cross-couplings (Suzuki-Miyaura, Mizoroki-Heck and Sonogashira reactions) led to buildings blocks that are direct precursors for the envisioned synthesis of push-pull solvatochromic dyes.
