Abstract:
The present invention relates to novel fluorinated alkoxyimines having the formula:R.sub.x --CF.dbd.N--O--CZ.sub.1 Z.sub.2 --CF.sub.3 (I)wherein:R.sub.x is either F or a perhalogenated alkyl group containing from 1 to 3 carbon atoms, andZ.sub.1 and Z.sub.2, either equal to, or different from, each other, are F, Cl, Br, H or a perfluorinated alkyl group containing from 1 to 3 carbon atoms.They are prepared by reacting a fluorinated alkoxyamine haivng the formula:R.sub.x --CF.sub.2 --NH--O--CZ.sub.1 Z.sub.2 --CF.sub.3 (V)with KF at a temperature comprised within the range of from 0.degree. C. to 100.degree. C.The present invention relates furthermore to the N-chloro- and N-bromo-derivatives of said fluorinated alkoxyimines (I), which derivatives have the formulae:R.sub.x --CF.sub.2 --NCl--O--CZ.sub.1 Z.sub.2 CF.sub.3 (VII)andR.sub.x --CF.sub.2 --NBr--O--CZ.sub.1 Z.sub.2 --CF.sub.3 (VIII).
