Pentafluorobenzoylpyruvic ester reacts with dinucleophiles - hydrazine, phe
nylhydrazine, hydroxylamine hydrochloride, 1,2-ethylenediamine, 1,2-phenyle
nediamine, 2-aminophenol - to form heterocyclic compounds. Reactions betwee
n bis(ethyl pentafluorobenzoylpyruvate)copper (II) chelate and these amine
hydrochlorides also produce heterocycles. The analytical data of these comp
ounds - elemental analysis, IR-, H-1 and F-19 NMR spectral data - are repor
ted. (C) 1999 Elsevier Science S.A. All rights reserved.
