Title:
PREPARATION OF PERFLUORO-OXYAZIRIDINE
Document Type and Number:
Japanese Patent JP3135659
Kind Code:
B2
Abstract:

PURPOSE: To simply obtain perfluoro-oxyaziridines in high yield which are useful in the preparation of perfluoroaminoether polymers, nitrones, etc., by reacting a specific perfluoroimine with an aromatic peroxyacid in an aprotic solvent at a specific temperature.
CONSTITUTION: A compound of formula I [wherein RZ is 1-10C perfluoroalkyl; RY is F or RZ; RX is RY or a group of formula II-NRf2 (wherein Rf is RZ)] is reacted with a compound of formula III [wherein X is an electron-attracting group such as F, Cl, -NO2, a group of formula IV: -COOR (wherein R is H or alkyl) and a group of formula V: -CONR2 or H] in an aprotic solvent such as dichloromethane and acetonitrile at a temperature of -50-+100°C to obtain the objective compound of formula VI.
