Photocatalytic Consecutive Photoinduced Electron Transfer-Enabled C(sp³)–H Pyridylation of Dihydroquinoxalin-2-ones

The Journal of Organic Chemistry, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 22, 2024

A photocatalytic decyanative C(sp3)–H pyridination of dihydroquinoxalin-2-ones with 4-cyanopyridines was developed by utilizing 4CzIPN as the photocatalyst. Mechanism studies show that this organophotocatalytic direct undergoes a radical–radical cross-coupling pathway promoted consecutive photoinduced electron transfer.
