An Electrochemical Study of the S-Derivatives of 2-Amino Cyclopentene-1-Dithiocharboxylic Acid in Aqueous Ethanolic Media

A systematic study on the electrochemical behavior of the S-derivatives of 2-amino cyclopentene-1-dithiocarboxylic acid (ACDA) has been carried out in aqueous ethanolic solutions by means of polarography, coulometry and voltammetry. All the compounds studied exhibited a well defined anodic wave corresponding to a diffusion controlled process. Controlled potential coulometry gave n=1 per mole for the anodic waves of the S-methyl and N-methyl S-methyl derivatives of ACDA, while for the dimer of ACDA a two electron oxidation wave was obtained.
