ABSTRACT:
The present invention relates to novel .omega.-fluorosulfato-perfluorocarboxylic acid derivatives of the formula I ##STR1## in which A denotes halogen, preferably Cl or F, and in particular F, or the group OR wherein R is alkyl, aryl or aralkyl with preferably up to 10 C atoms, in particular CH.sub.3 or C.sub.2 H.sub.5, m denotes a number from 1 to 10, preferably from 1 to 8 and in particular from 1 to 6, and n denotes a number from 0 to 10, preferably from 0 to 4 and in particular 0 or 1, which are prepared by electrolysis of .omega.-H-perfluorocarboxylic acid halides of the formula II ##STR2## in which A'=halogen and m and n have the same meaning as in formula I, in an electrolyte consisting of fluorosulfonic acid/alkali metal fluorosulfonate, the compounds of the formula III being formed: ##STR3## in which A' has the same meaning as in formula II and m and n have the same meaning as in formulae I and II, these compounds then also being esterified with an organic hydroxy compound of the formula IV
