  • Novel perfluorodiaziridines and process for preparing them
    Patent number: 4948903
    Abstract: Novel perfluorodiaziridiness having the formula: ##STR1## wherein: R.sup.1 and R.sub.2, alike or different from each other, represent a perfluoroalkyl group of from 1 to 10 carbon atoms, andR.sub.3 represents a fluorine atom, or a perfluoroalkyl group of from 1 to 9 carbon atoms.These perfluorodiaziridines are obtained by reacting perfluoroaminooxaziridines with a source of fluoride ions.
