Oxidation by permanganate: synthetic and mechanistic aspects

Oxidation of cefazolin by potassium permanganate: Transformation products and plausible pathways

“…Subsequently, the cyclic hypomanganate(V) ester was inclined to be rapidly oxidized to the corresponding cyclic manganate (VI) ester (intermediate 4) with excessively acid permanganate, followed by hydrolysis to form di-ketone-containing product m/z 519a (Lee and Brownridge, 1974;Wiberg and Saegebarth, 1957). This scheme is well supported by the prior reports (Dash et al, 2009;Ogino and Kikuiri, 1989).…”

“…Products m/z 471a and m/z 471b were identified as sulfoxide compounds in which oxidation of thioether occurred at S2 and S1 atoms, respectively. Likewise, product m/z 487 was the di-sulfoxide in which both thioethers of S1 and S2 (Dash et al, 2009;Xie et al, 2010;Rajasekharan et al, 2007), indicating that the oxidizing ability of KMnO 4 is comparable to that of HClO. Therefore, it was reasonable that these three products that were formed with HClO could also be produced after reaction with Mn(VII).…”

Inhibitory Effect of {Surfactant- MnO4-} Aggregation in KMnO4Oxidation of Proline and Methionine: A Kinetic Study

“…According to the results reported on oxidation by permanganate, 25 it is proposed that the alkali combines with permanganate to form an alkali-permanaganate species [MnO 4. OH] 2− , in a pre equilibrium step, which reacts with L-arginine or reacting species of the substrate in a slow step to form a free radical.…”

“…24 The results are also in agreement with the earlier reported work on the oxidation of aminoacid by alkaline KMnO 4 . 25 …”

Fresh Water Savings Through the Use of Municipal Effluents in Concrete Pavement

“…Furthermore, potassium permanganate has been widely used in water and wastewater treatment to control taste and odor, remove color, control biological growth in treatment plants, remove polycyclic aromatic hydrocarbons which have a carcinogenic and/or mutagenic potential (de Souza e Silva et al, 2009;Rodríguez et al, 2007); and potassium permanganate has several additional advantages such as easier to handle, readily soluble and higher efficiency in water and soil treatment over other oxidants (Xu et al, 2005;Yan and Schwartz, 1999). Unlike oxone, potassium permanganate gained momentum over a century ago and has increased in use due to its eco-friendly water/wastewater treatment applications around the world as well as its low cost (Dash et al, 2009;Kao et al, 2008).…”
