DiCobalt OctaCarbonyl, also known as Cobalt Carbonyl, is a versatile reagent and catalyst in organometallic chemistry and organic synthesis.

Chemical Structure

The structure of the compound consists of 4 carbonyl ligands on each cobalt atom and the two cobalt atoms linked to each other.

Properties & Applications

This compound decomposes to carbon monoxide and ultrafine cobalt powder when exposed to air / room temperature and is widely used as an in-situ source for cobalt atoms for catalysis, special reactions, organic synthesis, and other unique applications.

Potential Uses

• Production of tricyclic enone compounds, which are further hydrogenated to produce tricyclic ketone compounds. This is part of the production process for treprostinil, a synthetic analog for prostacyclin. The chemical is used in the treatment for hypertension.
• Catalytic carbonylation of epoxides, aziridines, thiiranes, oxetanes, lactones, lactams etc.
• Oxygenated organic compounds such as aldehydes, alcohols, esters can be produced by reacting olefins with carbon monoxide and hydrogen at elevated temperatures and pressures, in the presence of a cobalt catalyst.
• Reactions where a combination catalyst of cobalt source and pyridine are used.
• Hydroformylation of dodecene mixture, for preparing surfactant alcohols and surfactant alcohol ethers.
• Preparing derivatives of alpha-phenyl propionic acid.
• Synthesis of lupeose, an amorphous sugar.
• CVD coatings (chemical vapor deposition) made with DCOC and a silane to form cobalt silicide.
• Low temperature ALD (atomic layer deposition) or CVD coatings of cobalt based thin films.
