Process for the conversion of hydroxyl groups into the corresponding fluorine compounds

Process for the production of fluorine compounds, characterised in that hydroxyaliphatics, aromatics or enol compounds of the general formula 1 ##STR2## are reacted with 1-2 equivalents of perfluorobutanesulphonyl fluoride, or perfluorooctanesulphonyl fluoride in the presence of 2-3 equivalents of a strong organic base, which must not contain any reactive NH groups, in an inert organic solvent to yield the corresponding fluorine compound of the general formula 4, ##STR3## in which R.sub.1 denotes an optionally substituted linear or branched, aliphatic or araliphatic hydrocarbon

• and
• R.sub.2 and R.sub.3 denote hydrogen,
• or
• R.sub.1 and R.sub.2 designate optionally substituted linear or branched, aliphatic or araliphatic hydrocarbons
• and
• R.sub.3 is hydrogen,
• or
• R.sub.1 and R.sub.2 form a 4-8 or greater-membered aliphatic ring, which may in turn be part of an aliphatic or araliphatic polycyclic ring system
• and
• R.sub.3 is hydrogen.
