PHOTOELECTROCHEMICAL ELECTRON-SPIN-RESONANCE .4. THE PHOTO-ECE REACTION AND THE REDUCTION OF 1-HALOGENOANTHRAQUINONES

Abstract:

The reduction of 1-bromoanthraquinone in acetonitrile solvent in the presence of tetrabutylammonium perchlorate, at irradiated (565 nm) gold electrodes is shown to produce the radical anion of anthraquinone. A combination of photoelectrochemical hydrodynamic voltammetry, in situ electrochemical ESR and preparative experiments are used to deduce that the mechanism is a 'photo-ECE' reaction, in which the first electron transfer produces the radical anion of 1-bromoanthraquinone. On irradiation,...
