Title: Influence of fluorine substituents on the NMR properties of phenylboronic acids

Source: Magnetic Resonance in Chemistry

Year : 2014

Abstract:

The paper presents results of a systematic NMR studies on fluorinated phenylboronic acids. All possible derivatives were studied. The experimental H-1, C-13, F-19, B-11, and O-17 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 B-10/B-11 isotopic effect on the F-19 spectra and (4)J(FO) scalar coupling in organic compounds are reported.
