The Nuclear Magnetic Resonance Spectra of Some Boron Complexes

Abstract

Chemical shifts and coupling constants of a number of boron complexes are presented and discussed. Where available, shifts are compared with enthalpies of formation of the complexes. While BII resonance proves to be a poor criterion of stability, groups on the boron or groups in the ligand give shifts that can be correlated with enthalpies where available, provided the variations in structure of the compounds compared are held within narrow limits. © 1965, American Chemical Society.
