Abstract

The invention comprises carbamates and N-alkyl-carbamates (the alkyl group containing at most 4 carbon atoms) of fluorinated primary and secondary alkanols of the formula X-(CF2)n-CH(R)-OH (wherein R is hydrogen or methyl, X is hydrogen of fluorine and n is 2,3,4 or 5), the preparation of the N-unsubstituted carbamates by reacting the fluorinated alkanols with phenyl chlorocarbonate or phosgene and treating the resulting intermediate with ammonia, and the preparation of the N-alkyl-carbamates by reacting the fluorinated alkanols with the appropriate alkyl isocyanate. Examples are given. 3,3,4,4,5,5,6,6,7,7,7- Undecafluoro - 2 - heptanol is prepared from methyl undecafluoro-hexanoate and 1 mol of a methyl magnesium halide in the presence of 1.5 mols of an isopropyl magnesium halide.
