3-dimethylpentane (X), and perfluoro-3,4- dimethylhexane (III). Pyrolysis of IV in the presence of bromine gave (VI) and 3-bromo-3-trifluoromethyl-decafluoropentane (XI): with toluene, pyrolysis gare VlI and 3H-3-trifluoromethyldecafluoropentane (XII). Pyrolysis of II at 500° over glass gave perfluoro-1,2,3-trimethylcyclobutene (XIII) and perfluoro-2,3-dimethylpenta-1,3(E)- and (Z)-diene (XIV) and (XV) respectively

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
