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