ANODIC OXIDATION OF N-METHYLANILINE AND N,N-DIMETHYL-p-TOLUIDINE

Voltammetric Determination of Microparticles of Some Local Anesthetics and Antithusics Immobilized on the Graphite Electrode

“…The first step of all reactions is slow oxidation to unstable radical cations. In cyclic voltammetry the peak potentials of oxidation of p-aminobenzoic acid, aniline and p-anisidine [8,14,15]. The head-to-tail coupling of para-substituted anilines is followed by the elimination of one of substituents.…”

In situ FTIR spectroelectrochemistry and spectral simulations using DFT: Efficient complementary tools to elucidate complex electrochemical mechanisms

“…The electrochemistry of aniline and alkyl substituted anilines have been extensively studied in the light of their ability to form conducting polymers [9][10][11]. Previous studies of the electrochemical mechanism of oxidation of DMA in various media have shown that the formation of tetramethylbenzidine stemming from dimerization of the cation radical was an important step [12][13][14][15][16][17]. Electrochemical studies of the oxidation of DMA in acetonitrile have been performed previously by using ultramicroelectrodes and very high potential scan rates.…”

Oxidation of N-Methylanilines by a Nonheme Iron(IV)-Oxo Complex

“…29,30 But other possible coupling products such as benzidine and diphenylamine were not observed, which were predominant pathways for the electrochemical anodic oxidation of N-methylaniline. [32][33][34] The effects of ring substituents in para-substituted-Nmethylanilines (p-X-MAs) were also investigated on the 2+ with para-methyl-N-methylaniline and para-methyl-N-trideuteromethylaniline turned out 1.1, which strongly supports that only the electron transfer reaction from MA to the oxoiron(IV) intermediates is involved in the primary rate-determining step and the rate-determining electron transfer step not coupled with the following proton transfer.…”
