Abstract

Formazans 1-14 were prepared by the coupling reaction of phenylhydrazones and diazonium salts of aniline of -NO2, -CH3, -OCH3, -I, substituted anilines. The phenylhydrazones were synthesized by condensation of benzaldehyde or methyl-4-formylbenzoate with phenylhydrazine. The structures of the compounds were confirmed by IR, H-1 NMR and C-13 NMR. The dependence of lambda(max) upon the type of substituents and their positions on the phenyl ring was investigated using UV-visible spectra.
