Introduction of Fluorinated Groups via Photoredox-Catalyzed C–H Functionalization of (Hetero-)Arenes

In recent years, there have been increasing efforts in the development of methodologies for incorporating fluorine-containing functional groups into organic scaffolds. Modern techniques have made fluorinated molecules more accessible than ever before, but many fluorination reactions still have limitations in their generality, predictability, sustainability, and cost-effectiveness. The methodological progress has a significant impact on drug discovery and materials science research. Photoredox catalysis has enabled the discovery of effective methods, providing access to druglike molecules. Photochemical methods paired with C–H functionalization provide powerful tools for property-driven research. Herein, we examine recent developments at the interface of photoredox catalysis and C–H functionalization.
