Abstract

KUMAR KAKARLA, Ramana et al. Electrochemical studies of certain 1-(Toluenyl sulfonyl)-3-amino-4-(4'-substituted aryl hydrazono)-2-pyrazolin-5-ones. Rev.Colomb.Quim. [online]. 2011, vol.40, n.2, pp.165-184. ISSN 0120-2804.

The electrochemical behavior of certain 1-(Toluenyl sulfonyl)-3-amino-4-(4'-substituted aryl hydrazono)-2-pyrazolin-5-ones were studied 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.

Keywords : Polarographic studies; 1-(Toluenyl sulfonyl)-3-amino-4-(4'-substituted aryl hydrazono)-2-pyrazolin-5-ones; influence of variables; mechanism of electrode reaction.
