The addition of fluorine to perfluoro(4-methylpent-2-ene) or/and pcrfluoro(2-methylpent-2-ene) leads to perfluoro(2-methylpentane) (9) in good yield.78-80... 

Instructions for the conversion of polynuclear arenes (coronene, anthracene, decacyclene, naphthacene, naphthalene, pentacene, ovalene, 9,10-benzphenanthrene, 1,2-benzanthracene, 1,3,6,8-tetraphenylpyrene) into the corresponding perfluoro-alicyclic compounds and of 1,4-dichlorobenzene into perfluorocyclohexane by LaMar controlled-concentration direct-flow fluorination at room temperature and atmospheric pressure are now available in the patent literature, and precise details of the use of the method, in conjunction with a cryogenic reactor, to convert neopentane into perfluoroneopentane in low yield (10% after g.l.c. isolation) are also to hand. jhe results of kinetic studies on the direct fluorination of methane, [ H2]methane, halogenomethanes, and olefins are likewise in print. Treatment of the perfluoropropene dimers (CFsjsCiCF-CFs-CFs and trans-(CF3)2CF-CF -CF CFa with fluorine at —78 °C yields perfluoro-(2-methylpentane) quantitatively, while fluorination of a mixture of the trimers [(CFsjaCFlaC .CF-CFs and...
