Reaction conditions: 1 (0.10 mmol), HBpin (200 mol%), [Ir(OMe)(cod)]2 (2 mol%), ligand (4 mol%), THF (1.0 mL), 50 °C, 16 h. Yields were determined using GC (after calibration) or 1H NMR in the presence of an internal standard. Yields of the isolated products are shown in parentheses. See the Supplementary Information for details. Iridium-catalyzed C–H borylation of pharmaceutically relevant compounds on a gram scale is shown at the bottom. aAt 70 °C. bAt 60 °C. cAverage of two runs. dAt room temperature. Me methyl. Boc tert-butyloxycarbonyl. TIPS triisopropylsilyl.
