    Synthesis and spectroscopic studies of 4-adipoyl-bis (1-phenyl-3- methyl-pyrazolone-5) as a bis-(1,3-diketone)
    (NSF:Colombo, 1998) Uzoukwu, B.A.; Duddeck, H.; Okeke, S.I.
    4-Adipoylbis(1-pheny-3-methylpyrazolone-5)has been synthesised and Characterised spectroscopically using UV,IR,NMR and mass spectroscopy.The Compound was synthesised through a condensation reaction between pyrazolone and adipoyl chloride.The spectral data showed that the compound existed as a bis (1,3-diketonene).Assignments of the IR,NMR,and mass spectral results are reported.
