The paper presents results of a systematic NMR studies on fluorinated phenylboronic acids. All possible derivatives were studied. The experimental 1H, 13C, 19F, 11B, and 17O spectral data were compared with the results of theoretical calculations. The relation between the calculated natural bond orbital parameters and spectral data (chemical shifts and coupling constants) is discussed. The first examples of 10B/11B isotopic effect on the 19F spectra and 4JFO scalar coupling in organic compounds are reported.
