New fluorinated alkoxy imines and their N-chloro- and N-bromo-derivatives, and process for their preparation

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, and Z.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) and R.sub.x --CF.sub.2 --NBr--O--CZ.sub.1 Z.sub.2 --CF.sub.3 (VIII).
