‘Proton Sponge’ hydrofluoride has been prepared and is totally soluble in acetonitrile; this system has been used to generate carbanions from hexafluoropropene and to form carbon-fluorine bonds by reaction with both 2,4,6-trichloropyrimidine and benzoyl chloride.

Fluorination of perfluoroalkyl-pyridines, -pyrimidines, and -pyrazines, using cobalt trifluoride, gave corresponding aza- and diaza-cyclodienes, in some cases in high yields. Perfluoroalkylpyridazines gave products arising from loss of nitrogen and provide a novel route to some highly crowded perfluorinated olefins. Fluorination with elemental fluorine gave an unusal dimer with perfluoropyrimidine

Rearrangement of perfluoro-4,5-di-s-butylpyridazine (4) to a mixture of perfluoro-4,5-di-s-butylpyrimidine (13) and -2,5-di-s-butylpyrazine (20), occurs at 300 °C, in a sealed tube. Cross-over experiments between various fluorinatedpyridazine derivatives and, also, doubly 15N-labelled derivatives, rule out any rearrangementmechanism involving a cycloaddition process. Compound (4) and other fluorinated
