Abstract

A series of 2-(substituted phenyl)azo-4,6-dipropionylresorcinol derivatives (I-VI) have been synthesized by keeping in mind the eco friendly, low cost and high yield reaction. 2-(substituted phenyl)azo- 4,6-dipropionylresorcinols have been synthesized by diazotization of substituted aniline followed by coupling with 4,6- dipropionylresorcinol. All the synthesized compounds have been characterized by elemental analysis, IR, 1H NMR, 13C NMR and mass spectral analysis. In general azo compounds can exist in azo hydrazone tautomeric forms. But in our study, all the spectral data show that 2-(substituted phenyl)azo-4,6-dipropionylresorcinol derivatives (I-VI) exist in the azo form.

Keywords: azo, coupling, diazotization, dipropionyl, resorcinol, tautomerism.
