Herein, we describe an organic photoredox system for direct arene C–H radiofluorination using a peroxide oxidizing agent and LEDs as the light source. In conjunction with an optimized photocatalyst and a microtubing reactor, this system is applicable to a range of electron-rich aromatics and heteroaromatics. We also demonstrate the feasibility of C–H radiofluorination without an azeotropic drying step, which greatly simplifies the workflow of labeling process.
