Interaction of fluorine-containing 1,3-dicarbonyl compounds with polyamines
摘要:
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 21-35% 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-degrees-C in excess triethylenetetramine or ethylenediamine.
