Abstract
The invention comprises compounds of formula: <FORM:0963634/C1/1> where each of X, X1 and X11 is fluorine or chlorine, and their production by reacting CF2=CX1X11 with CF2=CF.NO and/or CF2=CCI.NO, e.g. at 50-100 DEG C. and 1-300 atmospheres. In examples (1) all X's are F, and (2) X=X1=F and X11=Cl.
Procedure for the obtaining of a product given of great stability, with all the properties dimanantes of active chlorine (Machine-translation by Google Translate, not legally binding)
