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.SDS of cas: 15813-09-9

Selective functionalization of imidazoles via an iodine-copper exchange reaction was written by Yang, Xiaoyin;Knochel, Paul. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2006.SDS of cas: 15813-09-9 This article mentions the following:

The reaction of protected 4,5-diiodoimidazoles with (PhMe2CCH2)2CuLi regioselectively provides 5-cuprated imidazoles, which readily react with various electrophiles furnishing functionalized imidazoles in good yields; remarkably, these resulting mono-iodoimidazoles undergo a second iodine-copper exchange reaction in the presence of sensitive functional groups, such as aldehyde or ketone. In the experiment, the researchers used many compounds, for example, 4,5-Diiodo-1H-imidazole (cas: 15813-09-9SDS of cas: 15813-09-9).
