Descrição geral
Osmium tetroxide (OsO4) is widely employed as a catalyst in various organic reactions.[1] Stereochemical aspects of the OsO4 assisted oxidation of allylic alcohols and their derivatives have been reported.[2] Its reaction with olefins has been investigated.[3] It participates as a catalyst for oxidizing fluoroquinolones, via reaction with potassium hexacyanoferrate(III) in alkaline medium. Kinetics of this oxidation reaction was studied.[1]
Aplicação
Osmium tetroxide may be employed as a catalyst for the hydroxylation of sterically hindered olefins.[4]
Osmium tetroxide may be used in the following processes:
To promote the lactonization of alkenols to lactones.[5]
To mediate the selective oxidative cleavage of olefins by oxone to form the corresponding ketones or carboxylic acids.[6]
Dihydroxylation of mono-trans-di, and trisubstituted olefins to form 1,2-diols with high enantioselectivity in the presence of chiral amines.[7]
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.[8]
