Combined experimental and theoretical study of long-range H–F interactions in α-fluoro amides

Abstract

A combined experimental and computational approach provided insight into the nature and conformational dependence of long-range 4JHF couplings in α-fluoro amides. The dependence of 4JHF on substituents and the solvent was investigated. H–F coupling constants determined by NMR spectroscopy are in agreement with DFT calculations. NBO analysis revealed that a favourable nF→σNH* interaction correlates with the magnitude of 4JHF.
