Visible Light-Induced\nOrganophotoredox-Catalyzed β‑Hydroxytrifluoromethylation\nof Unactivated Alkenes

Herein, we report a mild transition metal-free organophotoredox-catalyzed\napproach for β-hydroxytrifluoromethylation of unactivated alkenes\nusing CF<sub>3</sub>SO<sub>2</sub>Na and acridinium salt. The protocol\nis compatible with various mono-, di-, and trisubstituted aliphatic\nunactivated alkenes containing numerous functional groups and natural\nproduct derivatives. Further, the postsynthetic modifications of the\nsynthesized trifluoromethylated products have been demonstrated through\ncross-coupling and functional group interconversion reactions. The\nmethod proved to be scalable and it works smoothly under the direct\nexposure of sunlight. A plausible mechanism has been proposed based\non the fluorescence quenching experiment and cyclic voltammetry analysis.
