Description | Cyclopentadiene, also known as HCp or pentole, belongs to the class of organic compounds known as cycloalkenes. These are unsaturated monocyclic hydrocarbons having one or more endocyclic double bonds. Cyclopentadiene is a colorless liquid and has a strong or unpleasant odor. Cyclopentadiene is a highly reactive diene in the Diels–Alder reaction because minimal distortion of the diene is required to achieve the envelope geometry of the transition state compared to other dienes. Cyclopentadiene was the starting material in Leo Paquette's 1982 synthesis of dodecahedrane. Cyclopentadiene is a constituent of cannabis smoke and is formed during the combustion of cannabis ( Ref:DOI ). |
