Abstract
Polarographic reduction of 2-arylazo-2-bromo-5,5-dimethylcyclohexane-
1,3-diones takes place in a single step involving two
electrons. Well-defined, diffusion controlled, irreversible waves
are obtained in the pH range 2.0 -11.0. The Ei,2 value shifts
towards more negative potentials with increasing pH. Methyl,
Methoxy, chloro, bromo and ethoxy groups show positive polarographic
ortho shift (~o). The effect of substituents has been interpreted
in terms of the Hammett equation.
