REACTIVITY OF METHYL-SUBSTITUTED ANISOLE BY ELECTROCHEMISTRY

Electrochemical techniques allowed the comparison of reactivities betw een p-methylanisole, m-methylanisole and the anisole in acetonitrile / tetrabutylammonium tetrafluoroborate on platinum electrode, by evalua ting the homogeneous rate constant for an ECE type of mechanism, using cyclic voltammetry (CV), chronoamperometry (CA) and Specular Modulate d Reflectance Spectroscopy (SMRS). Such differences are mainly attribu table to the relative stabilities of the corresponding cation radicals and free radicals.
