2,3-Dihydro-1H-1,4-diazepines and 1,2,3,4-tetrahydro-1,4-diazeptin-5-ones were obtained by direct condensation of fluorine-containing 1,3-diketones and 1,3-keto ethers, respectively, with ethylenediamine monohydroperchlorate.The structure of the compounds was confirmed by 1H NMR, mass spectrometry and molecular weight determination.

2,3-Dihydro-1H-1,4-diazepines have been prepared by the direct interaction of fluoroalkylated 1,3-diketones with ethylenediamine hydroperchlorate; similarly, 1,2,3,4-tetrahydro-1,4-diazepine-5-ones have been obtained from fluorinated 1,3-keto esters.Under mild conditions, fluorinated copper(II) 1,3-diketonates, and coper(II) and nickel(II)N,N'-ethylenebis(aminovinyl ketonates) were found to react with ethylenediamine to form fluoroalkyl-containig N,N'-ethylenebis(aminovinyl ketones) and/or 2,3-dihydro-1H-1,4-diazepines.
