- School of Studies in Chemistry, Jiwaji University, Gwalior-474 011 Manuscript received 8 March 1985, revised 31 October 1985, accepted 17 January 1986 The polarographic reduction of 1-(2,4-dinitrophenyl)-3,5-dimethyl-4-arylazopyrazoles takes place in three well defined reduction waves. The first two waves each 4-e at more positive potentials have been assigned to the reduction of two nitro groups, whereas the third 2-e electron wave at comparatively negative potential has been assigned to the reduction of azo group. All the three waves were found to be diffusion-controlled and irreversible. A plausible mechanism has been suggested for the reduction of azo group as evident by the number of electrons involved in the reduction and controlled potential electrolysis The effect of substituents has been determined quantitatively by the application of Hammett equation
