chemical reduction was performed using aluminum hydride. The electrochemical reduction in 0.1 mol dm−3 TEAP/DMF was studied by cyclic and convolution potentialsweepvoltammetry at HDME. The title compounds exhibit two diffusion-controlled irreversible mono electronic cv waves. Both waves follow EC kinetics and they are attributed to the reduction of the pyrazolin carbonyl group. The kinetics of the chemical
