Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

open access: yesAngewandte Chemie, EarlyView.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.
