N, N'-Ethylenebis(1-phenyl-3-methyl-4-acylpyrazoloneimine) derivatives have
been synthesised and characterised using UV, IR, H-1 and C-13 NMR spectros
copy, where the substituents R(R')=CH3(H); CH3(CH3); CH3CH2(H); CH3CH2CH2(H
). The spectral data show that the compounds behave in solution as quadride
ntate ligands and the bis(hydroxyimine) tautomer is the most stable tautome
ric form in solution. The UV, IR, H-1 and C-13 NMR spectral assignments hav
e been reported.
