摘要：

The electrochemical characterization of 1,2-dimethyl-3,5-diphenyl-pyrazolium cation (difenzoquat) in water, methanol and acetonitrile is reported. Two-electron reduction in the range -1.27 to -1.52 V is coupled with a chemical step. The suggested mechanism includes dimerization of an intermediate and substituted pyrazoline as the product. The interpretation is based on dc polarography, cyclic voltammetry and UV spectra of the products of electrolysis.
