ethene12diiodide

Ethene-1,2-diiodide, also known as 1,2-diiodoethane, is a halogenated organic compound with the chemical formula C2H4I2. It is a vicinal dihalide, meaning the two iodine atoms are attached to adjacent carbon atoms in the ethane backbone. At room temperature, it exists as a colorless to pale yellow liquid or low-melting solid. Ethene-1,2-diiodide is sparingly soluble in water but is soluble in common organic solvents like ethanol and ether.

This compound can be synthesized through various methods. One common approach involves the reaction of ethene with iodine in the presence of a suitable catalyst or under specific conditions. Another method includes the reaction of ethylene glycol with iodine and a dehydrating agent.

Ethene-1,2-diiodide serves as a precursor in organic synthesis. It can undergo nucleophilic substitution reactions where the iodine atoms are replaced by other functional groups. It is also employed in the preparation of certain organometallic compounds. Due to the presence of iodine, it can be sensitive to light and heat, and should be stored appropriately. Its toxicity and environmental impact should be considered when handling and disposing of this chemical.
