Synthesis and electrochemical investigations on certain pyrazolin-5-ones

The electrochemical behavior of certain pyrazolin-5-ones was investigated at the dropping mercury electrode by employing DC polarography. The variables that influence the electrode process were extensively studied. All compounds under investigation gave two well defined polarographic waves. The mechanism for the electrode process was proposed in acid, as well as in basic media. The results obtained in polarography were compared with those obtained in cyclic voltammetry.
