Multinuclear NMR studies of the fluoride-uracil complex

(1)H, (19)F and (15)N NMR spectroscopy has been carried out on the soluble hydrogen bonded complex (CH3CH2)4N(1+)F(1-) (uracil).The studies suggest that deprotonation of the uracil does not occur and that in a medium dielectric constant solvent, hydrogen bonding occurs at the N(1)-H site.Spectroscopic monitoring of the controlled thermal decomposition of the complex shows that complex breakdown occurs via the uracil anion, HF2(1-) and neutral uracil.
