5iodopent1ene

5iodopent1ene is an organic compound with the chemical formula C5H9I. It is an iodoalkene, meaning it contains both an iodine atom and a carbon-carbon double bond. Specifically, it is a five-carbon chain with an iodine atom at one end (position 5) and a double bond between the first and second carbon atoms (position 1). Its IUPAC name reflects this structure.

This compound can be synthesized through various organic reactions. One common method involves the reaction of 1,5-dibromopentane with potassium iodide, a type of Finkelstein reaction, where the bromine atoms are replaced by iodine. Alternatively, it can be prepared from 1-penten-5-ol through a substitution reaction with an iodinating agent.

5iodopent1ene is a liquid at room temperature. Due to the presence of the double bond, it can undergo addition reactions typical of alkenes, such as halogenation or hydrohalogenation. The carbon-iodine bond is relatively weak and can participate in nucleophilic substitution reactions, making it a useful building block in organic synthesis for introducing a pentenyl group into other molecules. It is generally handled with care as many organohalogen compounds can have varying degrees of toxicity and should be stored properly.
