ABSTRACT:
New polyfluoroalkyl iodides of the formula ##EQU1## are provided, wherein R.sub.f represents a fluorinated hydrocarbon radical with 3 to 18 carbon atoms, R.sub.1 represents hydrogen or fluorine, R.sub.3 and R.sub.4 each independently represents hydrogen, lower alkyl, hydroxyalkyl, carboxy, carbalkoxy, --(CH.sub.2).sub.p OCOR.sub.2, in which R.sub.2 represents hydrogen or alkyl with 1 to 3 carbon atoms and p is 0 or a whole number from 1 to 3, phenyl and alkylphenyl, or R.sub.3 and R.sub.4 together with the carbon atoms to which they are bonded represent an optionally substituted cycloaliphatic radical with 5 or 6 ring carbon atoms, and n is a whole number from 1 to 3.
The new compounds are useful as intermediates for the manufacture of oil- and water-repellents, as oil- and water-repellents per se, as lubricants and as surface active assistants.
