ChemInform Abstract: A FLUORINE-19 NUCLEAR MAGNETIC RESONANCE STUDY OF THE STRONG HYDROGEN BOND BETWEEN ALIPHATIC DIOLS OR ACIDS AND ALKALI METAL FLUORIDES

Solutions of alkali metal fluorides in aliphatic diols or carboxylic acids have been investigated by 19F n.m.r. at concentrations of ca. 0.5 mol kg–1 and greater. Heats of association of potassium fluoride with ethane-1,2-diol and methanoic acid are obtained from variable-temperature n.m.r. studies. The nature of the strong hydrogen bond and its influence on the n.m.r. spectra are discussed.
