Abstract

Heavy alkali-metal fluorides are soluble in low-molecular-weight liquid aliphatic diols. Low-field shifts in the proton magnetic resonances of selected fluoride-diol solutions may be interpreted as being due largely to strong hydrogen bonding between the fluoride anion and the diol hydroxyls, although cation effects are also evident. Variable-temperature n.m.r. studies on KF-1, 2-ethanediol, CH3CN-1, 2-ethanediol, and neat 1, 2-ethanediol have been carried out and values of -(50 ±10) kJ mol-1 for ΔHe and -{130 ± 25) J K-1 mol-1 for ΔSe have been determined for the (F … HO)- hydrogen bond.
