Perfluoro-2,5-diazahexane-2,5-dioxyl and its use in polymer chemistry and in polymer cross-linking
Abstract
Perfluoro-2,5-diazahexane-2,5-dioxyl has been synthesised; it reacts with nitric oxide to give CF3·N(O·NO)·CF2·CF2·N(O·NO)·CF3, with hydrogen bromide, toluene, triphenylmethane, or hydrogen–Pd–BaSo4 to give CF3·N(OH)·CF2·CF2·N(OH)·CF3, and with perfluorinated olefins or dienes to give nitroso-rubbers and heterocycles, the latter type of reaction finding application in the cross-linking of trifluoronitrosomethane–tetrafluoroethylene–hexafluorobutadiene terpolymers.
