Abstract:
The present paper deals with the anodic oxidation of various benzylidenehydrazino-pyrazoles in several room-temperature ionic liquids containing the imidazolium scaffold towards a more environmentally friendly route in obtaining the corresponding pyrazolo-triazoles. We have studied the voltammetric response of the latter substrates on a platinum disc electrode by varying the nature of the imidazolium cation to find the most suitable reaction medium. By changing the substituents attached to the para-position of the phenyl ring within the substrates, we intended to better understand the nature of the formed intermediate and to elucidate the mechanism of their electrode reaction.
