Résumé:
In this work, ferrocenylmethyl alkyl imidazolium compounds and their salts were prepared, and their catalytic and electrochemical properties were studied. The effect of these salts as highly ligands in transition metal catalysis was demonstrated by catalytic studies using the hydrosilylation of the propiophenone reaction. Moreover, the electrochemical behavior of the synthesized derivatives has been studied using cyclic voltammetry, with the aim of finding the electronic effects of the imidazolium group on the ferrocene, understanding the reaction mechanisms at the anode, and calculating some electrochemical constants, as all the oxidation and reduction reactions of these derivatives represent stable, fast, reversible, single-electron and nemest systems, and that all defined by a responsible freight transport by the phenomenon of diffusion. In addition, the behavior and electrochemical properties of metallic triflates, which are excellent catalysts for most of the organic reactions, have been studied, we found that they are characterized by the reversion property, and the effect of water and diamine on their properties was studied using cyclic voltammetry.
