General description

Potassium permanganate (KMnO4) exhibits strong oxidizing properties.[1] KMnO4 on dissolution in benzene and on complexation with dicyclohexyl-18-crown-6, affords a useful oxidizing reagent. This reagent participates as an oxidant for the oxidation of olefins, alcohols, aldehydes and alkyl benzenes under mild conditions.[2]

Application

Potassium permanganate may be employed as an oxidizing agent in the synthesis of the following:
  • sulfonal (2,2-bisethylsulfonyyl)propane[3]
  • cinchomeronic acid (pyridine-3,4-dicarboxylic acid)[4]
  • isonicotinic acid (pyridine-4-carboxylic acid)[5]
  • manganese(IV) sulfate[6]
Suitable for heterogeneous oxidations.
Used for the decomposition of organic samples for the det. of mercury
