COBALT CARBONYL Chemical Properties,Uses,Production


Cobalt carbonyl (known as dicobalt octocarbonyl) is a versatile reagent and catalyst in organometallic chemistry and organic synthesis. It has catalytic applications in various chemical reactions such as hydroformylation of unsaturated compound, homogeneous hydrogenation of aromatic hydrocarbons, hydrosilation of alkenes, reactions of disulfides such as carbonylation to thio-esters and desulfurization to sulfides, hydroformylation as well as the conversion of alkenes into aldehydes. It can also promote both the Pauson-Khand reactions and Nicholas reaction.


  1. Reagent for the Pauson-Khand conversion of an olefin, an alkyne and carbon monoxide into a cyclopentenone.
  2. Precatalyst in combination with triphenylphosphite for the cataytic Pauson-Khand reaction.
  3. Catalyzes the rearrangement of 1-alkynylcyclopropanols to cyclopentenones.
  4. Catalyzes the conversion of aziridines to β-lactams.
  5. Catalyzes the conversion of diallylanilines and aryliminies to quinolines.
  6. Reagent for the selective cleavage of benzyl ethers.
  7. Domino Nicholas and Pauson-Khand process induced by nitroarene reduction.

Chemical Properties

red-orange to dark red crystals or flakes

Chemical Properties

Cobalt carbonyl is a pyrophoric (spontaneously flammable in air), red-orange (when pure) to dark-brown crystalline solid.


Cobalt octacarbonyl is used as a catalyst in the Oxo process. It also is used as a catalyst for hydrogenation, isomerization, hydrosilation and polymerization reactions. The compound is also a source of producing pure cobalt metal and its purified salts.


Toxic by ingestion and inhalation.

Safety Profile

Poison by inhalation and intraperitoneal routes. Questionable carcinogen. Decomposes in air to form a product that ignites spontaneously in air. "hen heated to decomposition it emits acrid smoke and fumes. See also CARBONYLS and COBALT COMPOUNDS.

Potential Exposure

This material is used as a catalyst for a number of reactions. It is also used in antiknock gasoline and for high-purity cobalt salts.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek Medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a Medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy


UN3124 Toxic solids, self-heating, n.o.s., Hazard Class: 6.1; 6.1-Poisonous materials, 4.2-Spontaneously combustible material. Technical Name Required. UN3190 Self-heating solid, inorganic, Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material, Technical Name Required. UN1325 Flammable solid, organic, n.o.s. Hazard Class: 4.1; Labels: 4.1-Flammable solid

Purification Methods

It forms orange-brown crystals on recrystallisation from n-hexane under a carbon monoxide atmosphere [Ojima et al. J Am Chem Soc 109 7714 1987; see also Hileman in Preparative Inorganic Reactions, Ed. Jolly, Vol 1 p 101 1987].


Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Decomposes on exposure to air or heat (@ ~52°C) producing toxic fumes of cobalt and oxides of carbon
