Abstract
The subject of the invention is functional chlorofluoro compounds of general formula: ##STR1## in which R.sub.F denotes a perfluoroalkyl radical, n is equal to 0 or 1, X denotes a chlorine or fluorine atom or a trichloromethyl or trifluoromethyl radical, and Y denotes a chlorine atom, an optionally salified or esterified hydroxyl group or an optionally substituted amino group, the arrangement R.sub.F --CCl.sub.2 --(CCl.sub.2 --O).sub.n containing at least 3 carbon atoms. By photochlorination of the esters R.sub.F --CH.sub.2 CH.sub.2 --O--CO--X, the compounds I (n=1) are obtained, which are then rearranged to acid chlorides I (n=0, Y.dbd.Cl) from which the corresponding acids, salts, esters and amides are optionally formed (formula I with n=0 and Y=optionally salified or esterified hydroxyl or optionally substituted amino).
