  • Perfluoroalkyl isoxazoles
    Patent number: 4000150
    Abstract: Perfluoroalkylated isoxazoles having the formula: ##EQU1## wherein R.sub.F is C.sub.3 - C.sub.15 perfluoroalkyl and R is the same as R.sub.F or a different C.sub.3 - C.sub.15 perfluoroalkyl or C.sub.1 - C.sub.7 alkyl or phenyl or phenyl substituted by C.sub.1 - C.sub.7 alkyl which are prepared by reacting hydroxylamine with a beta-diketone, at least one of whose alkyls is a C.sub.3 - C.sub.15 perfluoroalkyl, and dehydrating the resultant perfluoroalkylated 5-hydroxy-isoxazoline in an autoclave in the presence of polyphosphoric acid. The stable products are useful as heat-exchange media and as surfactants in organic solution.
