Analyse des Effets de Substituant du Noyau Benzenique EN RMN du Fluor: Application aux Fluoro-2 Alcools Phenylethyliques

Fluorine magnetic resonance shifts are reported for substituted 1- and 2-phenyl-fluoro-ethanols. They have been extrapolated at infinite dilution in solute and internal standard. The linear or other type correlations between these chemical shifts and substituent constants σ lead us to discuss the validity of linear free energy relationships extended to NMR data. The limits and possibilities of such relationships are emphasised.
