Cyclooctatetraene

Description:

Cyclooctatetraene (COT) is a cyclic hydrocarbon with the molecular formula C8H8, characterized by its unique structure consisting of eight carbon atoms arranged in a ring, with four alternating double bonds. This compound is notable for its non-planar, tub-shaped conformation, which arises from the strain associated with its eight-membered ring. COT is a colorless liquid at room temperature and has a distinctive aromatic odor. It is known for its reactivity, particularly in Diels-Alder reactions, due to the presence of its conjugated double bonds. Cyclooctatetraene is also an interesting compound in the study of aromaticity, as it does not exhibit the stability typically associated with aromatic compounds despite having a similar number of π electrons. Additionally, it can undergo polymerization and is used in various chemical syntheses. COT is soluble in organic solvents but has limited solubility in water. Its CAS number is 629-20-9, which is used for identification in chemical databases and regulatory contexts.
