Application: | Osmium tetroxide solution is used as catalyst in the: • Cis dihydroxylation of alkenes to form cis-1,2-diols. • Direct oxidation of 1,4-dienes to yield carboxylic acids using oxone as a co-oxidant. Osmium tetroxide can also be used: • In the stereoselective synthesis of (+)-norrisolide. |
General description: | Osmium tetroxide solution (OsO4) is commonly used as a catalyst in various organic reactions. OsO4 is a strong oxidizing agent and can be used to break carbon-carbon bonds. Additionally, it can be used in the cis dihydroxylation of alkenes, diastereoselective and asymmetric dihydroxylation, osmylation and oxyamination of alkenes. |
