    1,4-Hydroboration Reactions of Electron-Poor Aromatic Rings by N‑Heterocyclic Carbene Boranes за авторством Wen Dai (1607932)

    Опубліковано 2020
    “...When regioisomers are possible, the more crowded (doubly ortho-substituted) product is formed preferably or exclusively. The mechanism may involve oxidation of the NHC-borane to an NHC-boryl radical, reduction of the electron-poor aromatic ring to a radical anion, coupling of the radical and the radical anion to give a cyclohexadienyl anion, and finally regioselective protonation....”
