Depending on the nature of the dicarbonyl fragment, the reaction of fluorinated copper(II) bis(1,3-diketonates) with ethylenediamine and its monoprotonated salts under mild conditions gives N,N'-ethylenebis(aminovinyl ketones) and/or 1,4-diazepines.In excess ethylenediamine, copper(II) and nickel(II) N,N'-ethylenebis(aminovinyl ketonates) undergo cyclization to 1,4-diazepines.
