In the reaction of fluorinated copper(II) 1,3-diketonates with diethylenetriamine (or triethylenetetramine) in CHCl3, N,N'-bis(1,3-aminovinylketones) are formed in 21-35percent yields.Fluorine-containing 1,3-diketones and 1,3-ketoesters, upon interaction with polyamines without solvent, undergo acid cleavage, forming the corresponding amides.The copper(II) 1,3-ketoesterates are readily cleaved in CHCl3 at 25 deg C in excess triethylenetetramine or ethylenediamine. Keywords: copper(II) 1,3-diketonates and 1,3-ketoesterates, fluoroalkyl-containing 1,3-diketones and 1,3-ketoesters, ethylenediamine, diethylenetriamine, triethylenetetramine, N,N'-bis(1,3-aminovinylketones), acid cleavage.
