A 19F NMR Study of the Transmissive Ability of Boron-Containing Bridged Systems with Three- and Four-Coordinated Boron Atoms

Two series of model compounds, Ar₂BOC₆H₄F-4 and Ar₂B(Py)OC₆H₄F-4, containing three-and four-coordinated boron atoms, have been synthesized. It was established by ¹⁹F NMR technique that both systems possess a similar transmissive ability that is in intermolecular coordination with pyridine does not influence the transmissive properties of the boron-oxygen binuclear bridging group. The solvent polarity does not influence the electron transmission in the boron complexes studied.
