Abstract

We report a continuous-flow protocol for the trifluoromethylation of arenes, heteroarenes, and benzofused heterocycles. This photoredox methodology relies on the use of solid sodium trifluoromethanesulfinate (CF ₃ SO ₂ Na) as the trifluoromethylating agent and the iridium complex [Ir{dF(CF ₃)ppy} ₂ ](dtbpy)]PF ₆ as the photoredox catalyst. A diverse set of highly functionalized heterocycles proved compatible with the methodology, and moderate to good yields were obtained within 30 minutes of residence time.
