The Uses of Potassium osmate(VI) dihydrate

Potassium 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.

What are the applications of Application

Potassium osmate(VI) dihydrate is a reagent used in the oxidative cleavage of carboxylic acids and olefins to ketones

Reactivity Profile

catalyst for oxidative cleavage; oxidation reagent; used in dihydroxylation and aminohydroxylation reactions.

Hazard

Toxic by ingestion and inhalation.

storage

incompatible with strong oxidizing reagents. Toxic if inhaled. May cause respiratory tract irritation. Toxic if absorbed through the skin. Toxic if swallowed.

Structure and conformation

The complex anion is octahedral. Like related d2 dioxo complexes, the oxo ligands are trans. The Os=O and Os-OH distances are 1.75(2) and 1.99(2) Å, respectively. It is a relatively rare example of a metal oxo complex that obeys the 18e rule.
