  • Process for preparing perfluoro-oxyaziridines
    Patent number: 5241079
    Abstract: A process for preparing perfluoro-oxyaziridines of formula: ##STR1## where R.sub.x and R.sub.y, like or different from each other, are F or a C.sub.1 -C.sub.10, perfluoroalkyl group, R.sub.z is a C.sub.1 -C.sub.10 -perfluoroalkyl group. The process consists in reacting the corresponding perfluoroimine with a perfluoroalkyl fluoroformyl peroxide R.sub.f OOC(O)F, in the presence of an alkali metal fluoride MF, at a temperature ranging from -40.degree. to +50.degree. C.
    Type: Grant
    Filed: January 23, 1992
    Date of Patent: August 31, 1993

  • Method for preparing perfluoro-oxaziridines
    Patent number: 5229525
    Abstract: A process for preparing perfluoro-oxyaziridines of formula: ##STR1## where R.sub.x is F, a C.sub.1 -C.sub.10 perfluoroalkyl group or a --NR.sup.f.sub.2 group in which R.sup.f is a C.sub.1 -C.sub.10 perfluoroalkyl group, R.sub.y is F or a C.sub.1 -C.sub.10 perfluoroalkyl group and R.sub.z is a C.sub.1 -C.sub.10 perfluoroalkyl group. The process consists in reacting the corresponding perfluoroimine with an aromatic peroxyacid having a benzenic nucleus, in an aprotic solvent, at a temperature ranging from -50.degree. to +100.degree. C.
