“…It is known that phenolic compounds usually deactivate the commonly used electrodes during anodic oxidation, but there are few works about the electrochemistry of phenylethers in non-aqueous solvents. Those studies are restricted to preparative electrolyses, reaction kinetics in different solvents [1][2][3][4][5][6][7][8][9][10]. The examination of building up organic layers on electrode surfaces as modifiers offers useful information for several applications.…”

Electrooxidation of selected phenylethers was investigated (2-phenoxyethanol, anisole, o-nitrophenyl octyl ether, diphenylether, fenoxycarb) on platinum and glassy carbon electrodes. The chosen solvents were acetonitrile, dimethyl sulphoxide, 1-propanol and mesityl oxide. In acetonitrile, at around 2 V characteristic voltammetric peaks appeared for all compounds. In dimethyl sulphoxide and 1-propanol, no relevant peak appeared due to the high overlapping with solvent electrooxidation. During anodic oxidation of o-nitrophenyl octyl ether and fenoxycarb, a bimolecular reaction takes place predominantly. In mesityl oxide due to its unsaturated bond, identical behaviour was observed for majority of compounds and the differences between the two electrodes are also highlighted in the surface studies. The images made with the aid of an optical microscope showed the formation of islands of products for each substrate after deposition from mesityl oxide.

“…We demonstrated that the coupling of the radical cations issued from the first electron transfer was the governing reaction near the electrode. Particularly, under anhydrous conditions, successive coupling reactions, according to an (EC)n mechanism, led to conjugated oligomers from the polyphenylene family [3][4][5][6][7][8]. The methoxy group plays a crucial role in decreasing the oxidation potential and in the distonic character displayed by the generated radical cations.…”

The anodic reactivity of 4,4′-dimethoxychalcone: a synthetic and mechanistic investigation

et al. 2016

The anodic oxidation of the 4,4 0 -dimethoxychalcone (DMC) was investigated by different electrochemical methods at a platinum working electrode and in acetonitrile as a solvent. The DMC exhibited a single irreversible anodic peak around 1.6 V versus Ag/AgCl. On the time scale of cyclic voltammetry experiments, the highly reactive radical cation issued from the first electron transfer underwent a second order rate-limiting reaction. The potential imposed electrolyses of DMC led to the formation of a semi-conducting oligomer with 40 % yield. Using different physico-chemicals methods, the structural study confirmed the formation of an o-phenylenevinylene oligomer. The values of the corresponding optical and electrochemical band gaps were calculated to be 3.15 and 2.86 eV, respectively. Finally, a mechanism for the DMC electro-oligomerization was proposed on the basis of the obtained results.
