Шаблон:Short description Шаблон:Chembox
Cyclopentene is a chemical compound with the formula Шаблон:Chem2. It is a colorless liquid with a petrol-like odor. It has few applications, and thus is mainly used as a minor component of gasoline, present in concentrations of less than 1%.[1][2] It is one of the principal cycloalkenes.
Production
Cyclopentene is produced industrially in large amounts by steam cracking of naphtha. In the laboratory, it is prepared by dehydration of cyclopentanol.[3]
It can also be produced by the catalytic hydrogenation of cyclopentadiene.[4]

Reactions
Cyclopentene can be obtained from vinylcyclopropane in the vinylcyclopropane-cyclopentene rearrangement.[5]
The polymerization of cyclopentene by Ziegler-Natta catalysts yields 1,3-linkages, not the more typical 1,2-linked polymer.[6]
Palladium-catalyzed hydrocarboxylation of cyclopentene gives cyclopentanecarboxylic acid:[7]
