Abstract
The analysis of static and dynamic proton NMR spectra of 2-fluoro- and 2,6-difluoro-N,N-dimethyl- and N,N-diethyl-benzamides at various temperatures has been carried out. The conformations of the compounds have been deduced on the basis of long-range through-space proton-fluorine couplings. Free energies of activation of amide rotation have been determined for all compounds, and of carbonyl-ring rotation for one compound.
