The position directly adjacent to an aromatic group is called the benzylic position. Maintenance of a potassium permanganate device, Special considerations for potassium permanaganate use. Although overoxidation is less of a problem with secondary alcohols, KMnO4 is still not considered generally well-suited for conversions of alcohols to aldehydes or ketones. H2SO4 + KMnO4 reaction is an example of a double displacement reaction along with redox and precipitation reactions. Potassium permanganate is an inorganic compound with the chemical formula KMnO 4.It is a purplish-black crystalline salt, that dissolves in water as K + and MnO 4, an intensely pink to purple solution..

We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Under acidic conditions, the alkene double bond is cleaved to give the appropriate carboxylic acid:[42], Potassium permanganate oxidizes aldehydes to carboxylic acids, illustrated by the conversion of n-heptanal to heptanoic acid:[43], Even an alkyl group (with a benzylic hydrogen) on an aromatic ring is oxidized, e.g. 2fec 2o 4+2kmno 4+6h 2so 4fe 2(so 4) 3+2co 2+2mnso 4+k 2so 4+h 2o. Filo instant Ask button for chrome browser. Essentially the first step is that KMnO4 removes a hydrogen from the benzylic position, forming a benzyl radical, and the oxygen then "rebounds" back to the carbon to form C-O. Use the calculator below to balance chemical equations and determine the type of reaction (instructions). In fact, the most effective conditions for aldehyde oxidation by KMnO4 involves t-butanol as solvent with a NaH2PO4 buffer.2 The reactions above are deliberately not balanced equations.
