(1)H, (13)C, (19)F and (11)B NMR spectral reference data of some potassium organotrifluoroborates.

Roberta A Oliveira¹, Ricardo O Silva, Gary A Molander, Paulo H Menezes.

Abstract

Complete (1)H, (13)C, (19)F and (11)B NMR spectral data for 28 potassium organotrifluoroborates are described. The resonance for the carbon bearing the boron atom is described for most of the studied compounds. A modified (11)B NMR pulse sequence was used and better resolution was observed allowing the observation of (11)B-(19)F coupling constants for some of the studied compounds.
