Polyfluorinated hydrazones in organic syntheses

3. Reactions of poly- and perfluoroaldehyde hydrazones with hydrazine hydrate


The reaction of poly- and perfluoroaldehyde hydrazones with hydrazine hydrate was studied. A new preparative method for obtaining the hitherto inaccessibleN,N-unsubstituted bis-hydrazones of polyfluorinated α-oxoaldehydes was developed based on this reaction.
