Catalytic Photoredox C–H Arylation of 4-Oxo-4H-pyrido[1,2-a]pyrimidine-3-diazonium Tetrafluoroborates and Related Heteroaryl Diazonium Salts
[Image: see text] Irradiation of mixtures of title diazonium salts and heteroarenes with green light (510 nm) in the presence of eosin Y disodium salt (EY-Na(2)) as a photocatalyst furnished the corresponding arylation products in 8–63% yields. The proposed photocatalytic cycle is analogous to that...
