Application

Widely used oxidizer for visualizing cells in microscopy. Promotes oxidative cleavage of graphene layers in carbon nanotubes creating the possibility of opening ′windows′ in fullerene cages.

Osmium tetroxide may be used in the following processes:To promote the lactonization of alkenols to lactones.To mediate the selective oxidative cleavage of olefins by oxone to form the corresponding ketones or carboxylic acids.Dihydroxylation of mono-trans-di, and trisubstituted olefins to form 1,2-diols with high enantioselectivity in the presence of chiral amines.

Osmium tetroxide may be employed as a catalyst for the hydroxylation of sterically hindered olefins.

General description

Osmium tetroxide (OsO4) is widely employed as a catalyst in various organic reactions. Stereochemical aspects of the OsO4 assisted oxidation of allylic alcohols and their derivatives have been reported. Its reaction with olefins has been investigated. It participates as a catalyst for oxidizing fluoroquinolones, via reaction with potassium hexacyanoferrate(III) in alkaline medium. Kinetics of this oxidation reaction was studied.
