Abstract
The 19F n.m.r. spectra of solutions of tetraethylammonium fluoride in glacial ethanoic acid are consistent with F(MeCO2H)x – being the only significant fluoride species at concentrations above 0.01 mole fraction (0.004 mol kg–1). Below this the fluoride signal shifts upfield indicating an equilibrium involving a protonated fluoride postulated as [HF ⋯ H+⋯ O2CMe–]. The chemical shifts [p.p.m. (CFCl3)] of these species in this medium are –123 [F(MeCO2H)x –] and –217 [HF ⋯ H+⋯ O2CMe–]. There is no evidence for HF2 – as previously assumed.Keywords
