Using oxygen-18 labeled probes, the deactivation of the catalyst methyltrioxorhenium in oxidation reactions using hydrogen peroxide has been shown to result from the nucleophilic attack of HOO(-) on the parent catalyst rather than by HO(-) attack on intermediate A, opening possible routes to enhanced catalyst durability.
