13diiodobut2ene

1,3-Diiodobut-2-ene is an organic compound with the molecular formula C4H6I2. It is a colorless liquid at room temperature, with a boiling point of approximately 120°C. The compound is characterized by its two iodine atoms attached to the second and fourth carbon atoms of a butene backbone, with a double bond between the first and second carbon atoms.

1,3-Diiodobut-2-ene is typically prepared through the iodination of but-2-ene using iodine monochloride (ICl) or iodine (I2) in the presence of a suitable solvent. The reaction proceeds via an electrophilic addition mechanism, where the iodine molecule attacks the double bond of but-2-ene, leading to the formation of 1,3-diiodobut-2-ene.

This compound is of interest in organic synthesis due to its reactivity and potential as a precursor for further chemical transformations. It can undergo various reactions such as substitution, elimination, and addition, making it a valuable intermediate in the synthesis of more complex organic molecules.

In terms of safety, 1,3-diiodobut-2-ene is a hazardous substance. It is toxic if swallowed, inhaled, or absorbed through the skin. Prolonged exposure to the compound can cause skin and eye irritation. Proper handling and disposal procedures should be followed when working with this chemical to minimize potential health risks.
