| | BIS(CYCLOPENTADIENYL)COBALT Usage And Synthesis |
| Chemical Properties | dark violet crystals | | Uses | Polymerization inhibitor of olefins up to 200C,
Diels–Alder reaction, catalyst, paint drier, oxygen
stripping agent. | | Uses | Bis(cyclopentadienyl)cobalt is used to catalyze the preparation of pyridines from alkynes and nitriles. It acts as a polymerization inhibitor of olefins. It is a common one-electron reducing agent in the laboratory. It reacts with carbon monoxide to prepare cobalt(I) derivative, cyclopentadienylcobalt dicarbonyl. It also serves as an internal standard in cyclic voltametry. Further, it finds use in Diels-Alder reactions. In addition to this, it is used as a paint drier and as an oxygen stripping agent. | | Definition | A metallocene. | | General Description | Black-purple crystals or black solid. Sublimes at 104°F and 0.1 mm Hg. | | Air & Water Reactions | Air-sensitive. Highly flammable. Insoluble in water. | | Reactivity Profile | BIS(CYCLOPENTADIENYL)COBALT is very sensitive to air and is readily oxidized. BIS(CYCLOPENTADIENYL)COBALT is also sensitive to exposure to light. Readily oxidized by water and dilute acids . | | Hazard | Toxic by ingestion. | | Health Hazard | ACUTE/CHRONIC HAZARDS: BIS(CYCLOPENTADIENYL)COBALT is toxic by ingestion. | | Fire Hazard | Vendor information indicates that BIS(CYCLOPENTADIENYL)COBALT is flammable. | | Safety Profile | Poison by intraperitoneal route.Questionable carcinogen with experimental tumorigenicdata. Mutation data reported. When heated todecomposition it emits acrid smoke and fumes. |
