Tetraiodoethylene is a chemical compound with the formula C2I4. It is an organoiodine compound and is structurally related to ethylene, where all four hydrogen atoms are replaced by iodine atoms.

Properties

Tetraiodoethylene is a colorless solid at room temperature. It is known for its high density and relatively low melting point compared to other tetrahalogenated ethylenes. The compound is sparingly soluble in water but soluble in organic solvents such as chloroform and benzene.

Synthesis

Tetraiodoethylene can be synthesized through the iodination of ethylene or by the reaction of tetrachloroethylene with iodine in the presence of a catalyst. The reaction typically proceeds as follows:

C2Cl4 + 4 I2 → C2I4 + 4 Cl2

Applications

Tetraiodoethylene is used in organic synthesis and as an intermediate in the preparation of other organoiodine compounds. It is also utilized in the study of halogen bonding and in various chemical research applications.

Safety and Handling

Like many organoiodine compounds, tetraiodoethylene should be handled with care. It is important to use appropriate personal protective equipment (PPE) such as gloves and goggles when working with this compound. It should be stored in a cool, dry place away from light and moisture.
