Reaction Conditions

Temperature	50 °C

Reaction Steps

Following general procedure F using N‐(2,3‐dihydro‐1H‐inden‐1‐yl)‐2,2,2‐trifluoroacetamide (57.3 mg, 0.25 mmol), B2pin2 (95 mg, 0.375 mmol), [Ir(COD)OMe]2 (2.5 mg, 0.00375 mmol) and dtbpy (2.0 mg, 0.0075 mmol) in THF (1.25 mL). The reaction was stirred at 50 °C for 20 hours before cooling and the solvents removed. Analysis of crude 1 H NMR using internal standard 1,2‐dimethoxyethane showed 29:16:6:33 dimeta:meta1:meta2:para borylation in 84% yield.
