    摘要: 1-[2,2-bis(trifluoromethyl)-3,3,4,4,5,5,5-heptafluoropentyl]-3,5-diaminobenzene and 1-[2,2-bis(trifluoromethyl)-3,3,4,4,5,5,5-heptafluoropentyl]-4-aminobenzene, as well as fluorinated polymers, preferably polyimides. The perfuuoroalkyl group of these amines is connected to the benzene ring through a tertiary carbon atom followed by a methylene group. This renders the amines more reactive than other amines, where the perfluoroalkyl group is connected directly to the benzene ring. The absence of hydrogen from the group containing the tertiary carbon atom which is adjacent to the perfluorinated groups, prohibits dehydrofluorination.

    摘要: Novel fluorohydrocarbons include a fluoroalkyl unit terminating in a tertiary carbon atom which is directly linked to an aliphatic moiety of the compound. The compounds contain at least 9 carbon atoms and usually no more than 13 carbon atoms. The compounds are synthesized by addition of a fluoride atom to the tertiary carbon atom of a fluorocarbon material to form a carbanion followed by alkylation of the carbanion. The fluorohydrocarbons will find use as blood substitutes or as electronic fluids.
