Two mechanisms are proposed for the cooxidation of oxalic acid and isopropyl alcohol by chromium(VI). The results of the /sup 13/C-isotope effect studies on the mechanism demonstrate the presence of a significant carbon isotope effect. This /sup 13/C-isotope effect together with a previously established deuterium isotope effect is taken as providing compelling evidence for the synchronous C--H and C--C bond breaking and thus for a three electron mechanism in the cooxidation reaction.
