Studies of Solvated Electrons in Libr+hmpa Solutions Using the Rotating-Ring-Disk Electrode Technique .2. The Reaction of Benzene with Solvated Electrons

Vanandelscheffer PJ, Wonders AH, Barendrecht E

By means of a rotating ring-disk electrode (RRDE) it was found that in LiBr + hexamethylphosphoramide (HMPA) solutions solvated electrons react very slowly with water, even at concentrations higher than 1 M. The reaction of benzene with solvated electrons in LiBr + HMPA solutions takes place only in the presence of a proton donor such as water. A second-order reaction rate constant was determined for this reaction and was found to be 0.26 x 10(3) M-1 s-1 at a disk current of - 1.25 mA.
