The diorganoselenium and selenides compounds electrochemistry.
The electrochemical behavior of Ar(2)SeCl(2), and Ar(2)Se(2), (Ar:CH(3)OC(6)H(5); C(2)H(5)OC(6)H(5)) in acetonitrile (AN) containing tetrabutylammonium tetrafluoroborat (TBAFB) as supporting electrolyte was studied on a stationary electrode (spe). In order to elucidate the electrode reactions linear potential scan, cyclic voltammetry and controlled-potential coulometry were employed using a platinum electrode. It is shown that Ar(2)SeCl(2) and Ar(2)Se(2) are reduced and oxidized to Ar(2)Se, Ar(2)Se(2)Ar(2), Se, and Ar(2)Se(BF(4))(2). It is generally accepted that as final electrochemical reduction products, the corresponding Ar(2)Se, Ar(4)Se(2), and Se were formed. The disappearance of the diorganoselenium and selenide in the course of the coulometric experiments was validated by measuring the limiting current of the voltammetric waves at spe and UV spectrometry.
