The transamination of 2-amino-4-imino-2-perfluoropentene with ethylenediamine gives the corresponding 6-fluoro-5,7-bis(trifluoromethyl)-2,3-dihydro-1H-1,4-diazepine. The transamination of 2-amino-4-imino-2-perfluoropentene by diethylenetriamine is accompanied by intramolecular nucleophilic substitution of the α-fluorine atom to form 1,9-bis(trifluoromethyl)-3,4,6,7-tetrahydro-2H-pyrazino[1,2-a]pyrazine
Interaction of perfluoropentene-2 with ethylenediamine, diethylenetriamine, and triethyleneletramine forms previously unknown fluorine-containing azaheterocycles in yields of 25-74%. The structure of the compounds obtained has been confirmed by H-1 and F-19 NMR methods and mass spectrometry.
