What is a Cyclooctatetraene (C₈H₈)?

Cyclooctatetraene (C₈H₈) is an organic compound with an eight-membered ring structure, featuring alternating double bonds. It is a highly reactive and unstable compound, known for its ability to form metal complexes, which are useful in organic metal chemistry and catalytic reactions. It is a colorless to pale yellow liquid with an aromatic odor. Cyclooctatetraene plays a key role as an intermediate in chemical syntheses, particularly in reactions involving organometallic chemistry. Although it is relatively low in toxicity, it is highly flammable and should be handled with care to avoid inhalation or prolonged skin contact. Its environmental impact is moderate, as it is not very soluble in water and can persist in the environment.
