Regioselective C3-Fluoroalcoholation of Indoles with Heptafluoroisopropyl Iodide via Palladium-Catalyzed C(sp<sup>2</sup>)–C(sp<sup>3</sup>) Cross-Coupling in the Presence of O<sub>2</sub>
An efficient method for C3-fluoroalcoholation of indole derivatives was developed by merging C–F cleavage and C–C bond coupling, using free (NH)-indoles and heptafluoroisopropyl iodides as precursors. Preliminary mechanistic studies indicate that the bimetallic co-mediated C–F bond cleavage and the trifluoroacetate moiety play an essential role. Notably, this strategy constructs derivatizations through
