The oxidative coupling of secondary aldehydes and sulfinate salts is achieved using copper catalysis to form α-sulfonyl aldehydes. The use of an ,acidic, co-solvent is important to adjust the ,oxidation, potential of MnO₂ as an oxidant. A broad range of sulfonylated aldehydes is prepared, and their further functionalisation is demonstrated.

In neutral solution, ,permanganate, is only reduced by 3e- to give ,MnO2,, wherein Mn is in a +4 ,oxidation, state. This is the material that stains one's skin when handling KMnO4. KMnO4 spontaneously reduced in an alkaline solution to green-coloured K2MnO4, wherein manganese is in the +6 ,oxidation, state.

And ethanol reactions: KMnO4 + C2H5OH = KOH + CH3COOH + MnO2 (withdrawals strong potassium permanganate oxidation) CH3COOH + KOH = CH3COOK + H2O . Therefore, the overall reaction equation is; KMnO4 + C2H5OH = MnO2 + CH3COOK + H2O Preparation . Due to high demand laboratories, potassium permanganate is manufactured on a large scale.

5.1.1 ,Oxidation, Potential ,Potassium permanganate, is highly reactive under conditions found in the water industry. It will oxidize a wide variety of inorganic and organic substances. ,Potassium permanganate, (Mn 7+) is reduced to manganese dioxide (,MnO2,) (Mn 4+) which precipitates out of solution (Hazen and Sawyer, 1992). All reactions are exothermic.
