Alkane R-CH3 Aqueous potassium permanganate was used originally for the conversion of alkenes into diols (Wagner dihydroxylation reaction) (Scheme 1). Owing to the rapidity and the complex mechanism of the per-manganate oxidations, the mechanisms of oxidation of various olefinic derivatives are still poorly understood. $\ce{H2CrO4}$ Oxidation occurs in acid, $\ce{KMnO4}$ oxidation occurs in base The source of the nucleophile in the removal of the metal ester. In $\ce{KMnO4}$ oxidation, the $\ce{Mn}$ ester itself extracts the $\ce{H+}$ from the alcohol carbon, while in $\ce{H2CrO4}$ oxidation the nucleophile is the solvent. Oxidation experiments with potassium permanganate were conducted in 500 mL amber bottles (Fisher Scientific, Whitby, ON, Canda). All reactor assays were performed in duplicates. For ultrapure water (Milli-Q) samples, the pH was adjusted to 6.0 and 8.0 using the appropriate buffered phosphate solutions prior to the oxidation tests.
