ELECTROCHEMICAL-BEHAVIOR OF 3-METHYL-4-(SUBSTITUTED-BENZENEAZO)-2-ISOXAZOLIN-5-ONES

Electrochemical reduction of 3-methyl-4-(substituted-benzeneazo)-2-isoxazolin-5-ones has been carried out in Britton-Robinson buffers in the pH* range of 1.66-9.66. All the compounds give single, well-defined, diffusion-controlled, irreversible reduction wave at d.m.e. while at HMDE one cathodic peak is observed at low scan rates and two cathodic peaks at high scan rates in acidic solutions and a single cathodic peak is observed in alkaline solutions at all scan rates. The products of electrolysis have been characterised and a plausible mechanism of electroreduction has been suggested.
