Abstract
DESCRIPTORS: *Polymers, *Fluorocarbons, *Azo radicals, *Methanes, *Heterocyclic compouns, Chemical reactions, Decomposition, ACIDS, Hydroxides, Subtitution reactions, USSR, Synthesis.A number of heterolytic conversions of polyfluorinated azoalkanes are shown for the first ime. Polyfluorinated azoalkanes are extremely unstable toward oxdizing agents (halogens, H2O2, peracis, hypochlorites). Reduing agents uch as HI, H2S, HP in polar media (ether, methanol) in the cold easily rect with the azo compounds studied, conveting the azo group into an hydrazo group. Hexafluorohydrazomethane posesses pronounced aciic properties and is comparatively stable in solvated form (etherate and acetonate). AT THE SAME TIME, THE CF3NH groups in hexafuorohydazomethane can easily eminate HF in bases. Hexafluoroazomethane was the most electrophlic of the polyfluorinted azoalkanes studied. In reactions with amines containing an NH group, mecaptans and sulfinic acids, azo compounds behave similaly to azodicrboxylic eters, but are less active. The primary produts undergo further conversion due to the CF3NH group. Author)
