¹⁹F N.M.R. spectroscopy. III. The fluoroformyl group

Abstract

The fluorine-19 nuclear magnetic resonance spectra of a representative group of cyclohexanecarbonyl fluorides have been measured in order to test the suitability of fluorine as a probe for assigning the configuration of carboxyl groups. The data also lead to an evaluation of the conformational energy of the fluoroformyl group.
