| Research Abstract |
A lot of reports can be found, demonstrating that the reaction rate or selectivity, is significantly enhanced by microwaves, compared with the conventional heating method. These microwave effects are usually classified as either thermal or non-thermal. We assume that microwaves decrease the reorientation energy in electron transfer reactions. Therefore, we have selected one electron transfer reduction of viologen derivatives by nickel metal particles dispersed in water for revealing the MW effects. Viologen derivatives with different reduction potentials were reduced by Ni particles under microwave irradiation and found to be enhanced in comparison with oil bath heating, demonstrating an evidence for the accelerating effect of electron transfer on solid surface by microwaves.
