Described herein is an unsaturated fluorinated compound of formula (I) where X is O or N; Y is F or H; Z is F or CF3; and A is F or CF3 wherein when X is O, then n is 1, Y is H, Z is F, A is F, and Rf is a linear or branched perfluorinated alkyl group comprising 1 to 10 carbon atoms and optionally comprising at least one catenated O or N; and when X is N, then n is 2 and each Rf group are (i) independently selected from a linear or branched perfluorinated alkyl group comprising 1 to 8 carbon atoms and optionally comprising at least one catenated O or N; or (ii) bonded together to form a ring structure comprising 4 to 8 carbon atoms and optionally comprising at least one catenated O or N with the proviso that when Z is CF3 then A is F and when A is CF3 then Z is F and methods of making and using the same.
perfluoropiperidino- and perfluoropropoxy-subs perfluoroalkyl iodides were synthesized directly by the reaction of the corresponding perfluoroacylfluorides with lithium iodide in high yield. Under controlled reaction conditions, it was possible to synthesize either iodo-perfluoroacyl fluorides or perfluoroalkylidene diiodides by the reaction of perfluoro(alkanedioyl) difluorides with lithium iodide.
