Potassium osmate(VI) dihydrate Usage And Synthesis
DescriptionPotassium osmate (VI) dehydrate is an inorganic compound with the formula H4K2O6Os. ISn the VI (6+) oxidation state the compound is a diamagnetic purple salt contains osmium. It is soluble in water and slowly decomposes in aqueous solution. Potassium osmate (VI) dehydrate is insoluble in ethereal and alcoholic solvents.
PreparationEdmond Fremy first prepared potassium osmate (VI) dehydrate in 1844 by reducing perosmates using alcohol.
2OsO4 + C2H5OH + 3 KOH → CH3CO2K + 2 K2[OsO2(OH)4]
Applications and ReactionsPotassium osmate (VI) dehydrate is used as a catalyst in the dihydroxylation of cyclic internal alkenes such as lactams, 1,2 dioxines dihydrothiophenes and hexahydropyrans. The resulting diols from such reactions have been used in the preparation of various carbohydrate and similar molecular scaffolds. Potassium osmate (VI) dehydrate iss also used in the development of an asymmetric dihydroxylation methodology targeting heteroaromatic acrylates.
Chemical Propertiesviolet crystalline powder
UsesDetermination of nitrogenous matter in water.
UsesPotassium osmium(VI) oxide dihydrate acts as a catalyst for the oxidative cleavage of olefins to ketones and carboxylic acids. It is employed in an intramolecular amidohydroxylation of carbamoyloxytethered olefins providing hydroxy oxazolidinones. It is also used as a reagent in the synthesis of amphidinolide B, which shows potent antitumor activity against human solid and blood tumor cells.
HazardToxic by ingestion and inhalation.
