Conclusions

  1. 1.

    The acid hydrolysis of amides ofα-amino-andα,α-diaminoperfluorocarboxylic acids have been studied. In the diaminoamides, the gem-diamino grouping hydrolyses first and then (under more severe conditions) in the amide function, which leads to the formation ofα,α-dihydroxyperfluoroearboxylic acids (hydrates ofα-oxoperfluorocarboxylic acids). In the hydrolysis ofα-aminoperfluoroisobutyramide, the unstableα-aminoperfluoroisobutyric acid is formed which immediately undergoes decarboxylation to form hexafluoroisopropylamine.

     
  2. 2.

    α-Hydroxyperfluoroisobutyric andα-oxo-ω-hydroperfluorocaprylic acids have been obtained by the hydration of perfluoroisobutylene oxide andω-hydroperfluorooctene oxide, respectively.

     
  3. 3.

    The acylation ofα-aminoperfluorobutyramide andα,α-diaminoperfluoropropionamide has given the corresponding mono- and bis (acylamino)amides.
