4,5-Diiodo-1H-imidazole (cas: 15813-09-9) belongs to iodide derivatives. Iodide-containing intermediates are common in organic synthesis, because of the easy formation and cleavage of the C–I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Product Details of 15813-09-9

Halogen and Hydrogen Bond Architectures in Switchable Chains of Di- and Trihaloimidazoles was written by Andrzejewski, Michal;Marciniak, Jedrzej;Rajewski, Kacper W.;Katrusiak, Andrzej. And the article was included in Crystal Growth & Design in 2015.Product Details of 15813-09-9 This article mentions the following:

Halogen bonds have been employed for controlling the structure of NH···N hydrogen-bonded chains in halogenated imidazoles; the CH···halogen contacts stabilize the coplanar arrangement of mols., whereas the halogen···halogen contacts twist the mols. around the NH···N bonds and stretch their N···N distances. The interplay of halogen···halogen and NH···N hydrogen bonds leads to isostructural relations of 4,5-dihaloimidazoles as well as between trichloro- and tribromoimidazole. However, the increasing steric hindrance excludes the triiodoimidazole from this isostructural series, and the triiodo derivative forms an unusual structure with three symmetry-independent mols. All sym. substituted 4,5-dichloro-, dibromo-, and diiodoimidazoles as well as trichloro-, tribromo-, and triiodoimidazoles have been synthesized and crystallized and their structures determined The derived rules also apply to the co-crystal structures of 4,5-diiodoimidazole:2,4,5-triiodoimidazole as well as to 4-iodoimidazole:2,4-diiodoimidazole. The halogen interactions prove an efficient means for engineering and tuning new materials with desired dielec. properties relying on highly polarizable NH···N hydrogen bonds. In the experiment, the researchers used many compounds, for example, 4,5-Diiodo-1H-imidazole (cas: 15813-09-9Product Details of 15813-09-9).
