A permanganate (/ pərˈmæŋɡəneɪt, pɜːr -/) [1] is a chemical compound with the manganate (VII) ion, MnO−. 4, the conjugate base of permanganic acid. Because the manganese atom has a +7 oxidation state, the permanganate (VII) ion is a strong oxidising agent. The ion is a transition metal ion with a tetrahedral structure. [2]
For example, addition of potassium permanganate to an aqueous solution of sugar and sodium hydroxide produces the chemical chameleon reaction, which involves dramatic color changes associated with the various oxidation states of manganese. A related vigorous reaction is exploited as a fire starter in survival kits.
Potassium manganate is the inorganic compound with the formula K2MnO4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO4), a common chemical. [ 1 ] Occasionally, potassium manganate and potassium per manganate are confused, but each compound's properties are distinct.
The oxidation of primary alcohols to carboxylic acids normally proceeds via the corresponding aldehyde, which is transformed via an aldehyde hydrate (gem-diol, R-CH(OH) 2) by reaction with water. Thus, the oxidation of a primary alcohol at the aldehyde level without further oxidation to the carboxylic acid is possible by performing the reaction ...
Manganate. In inorganic nomenclature, a manganate is any negatively charged molecular entity with manganese as the central atom. [1] However, the name is usually used to refer to the tetraoxidomanganate (2−) anion, MnO 2−. 4, also known as manganate (VI) because it contains manganese in the +6 oxidation state. [1]
Permanganic acid (or manganic (VII) acid) is the inorganic compound with the formula H MnO 4 and various hydrates. [3] This strong oxoacid has been isolated as its dihydrate. It is the conjugate acid of permanganate salts. It is the subject of few publications and its characterization as well as its uses are very limited.
Dihydroxylation. Dihydroxylation is the process by which an alkene is converted into a vicinal diol. Although there are many routes to accomplish this oxidation, the most common and direct processes use a high-oxidation-state transition metal (typically osmium or manganese). The metal is often used as a catalyst, with some other stoichiometric ...
