Abstract
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.
Claims11
A fluorochemical compound containing 9 to 15 carbon atoms selected from compounds of the formulae:
- ##STR12## where R.sub.f =C.sub.n F.sub.2n +1
- R.sub.f '=C.sub.n' F.sub.2n' +1
- R.sub.f "=C.sub.n" F.sub.2n" +1
- and n, n' and n" are integers from 1 to 11 and Z is a hydrocarbon moiety containing at least 2 hydrogen atoms and has a methylene group connected to the tertiary carbon atom.
