✦ Synopsis

The kinetics of the oxidation of glutathione by diaquatetrakis(2,2'-bipyridine)-#-oxo diruthenium(III) ion in aqueous HC104 have been investigated. The reaction obeys the empirical rate law:

where k=7.42_+0.40• -1 at 25.5~

[H+]= 0.005-0.05 M and I = 1.0 M (LiC104). Free radicals are important in the reaction and a mechanism consistent with the experimental results has been postulated.
