Scope of the hydrogen bond‐directed meta‐selective borylation.^[a,b]

[a] Typically: Substrate (0.25 mmol), B₂Pin₂ (0.375–1.0 mmol), [Ir(COD)OMe]₂ (1.5 mol %), 1 a (3 mol %), THF (0.2 m), RT to 70 °C (see the Supporting Information for details). [b] Isomeric ratios are meta:para taken from analysis of crude ¹H‐NMR spectra; yields shown are isolated unless otherwise indicated and include meta and para isomers which are generally inseparable. [c] NMR yield quoted due to decomposition on silica gel. [d] Product isolated as mixture of mono‐ and diborylated compounds.
