14diiodobut2ene

14diiodobut2ene is an organic compound with the chemical formula C4H6I2. It is a diiodoalkene, meaning it contains two iodine atoms and one carbon-carbon double bond. The "2ene" indicates the double bond is located between the second and third carbon atoms of the butane chain. The "1,4diiodo" specifies the positions of the two iodine atoms at the terminal ends of the molecule. This molecule exists as geometric isomers due to the presence of the double bond. The two possible isomers are (2E)-1,4-diiodobut-2-ene and (2Z)-1,4-diiodobut-2-ene. The E isomer has the iodine atoms on opposite sides of the double bond, while the Z isomer has them on the same side.

The synthesis of 1,4-diiodobut-2-ene can be achieved through various organic reactions. One common method involves the reaction of a suitable precursor, such as but-2-yne, with iodine under specific conditions. Alternatively, it can be prepared from but-2-ene-1,4-diol by converting the hydroxyl groups into good leaving groups, followed by nucleophilic substitution with iodide ions. The physical properties of 1,4-diiodobut-2-ene, such as melting point and boiling point, are influenced by its isomeric form and purity. Due to the presence of carbon-iodine bonds, this compound is typically a solid or a high-boiling liquid. Its reactivity is characteristic of alkenes and organic iodides, participating in reactions like addition across the double bond or substitution of the iodine atoms.
