Modular synthesis of helicene-like compounds based on the imidazolium motif was written by Cizkova, Martina;Saman, David;Koval, Dusan;Kasicka, Vaclav;Klepetarova, Blanka;Cisarova, Ivana;Teply, Filip. And the article was included in European Journal of Organic Chemistry in 2014.Synthetic Route of C3H2I2N2 This article mentions the following:
Straightforward synthesis of novel mono- and tricationic helical compounds based on the imidazolium core was developed. The synthetic route based on double [2+2+2] cycloaddition reactions of precursors with the imidazolium core motif is notably modular and reaches beyond established protocols used for the synthesis of imidazolium systems as well as beyond the reported protocols used to assemble compounds with helical frameworks. This approach opened rapid four-step access to a cationic species featuring nine ortho-annulated rings that represents the highest order helical nitrogen-based cationic system reported to date. The structure of 2 was confirmed by the single crystal x-ray diffraction anal. [monoclinic, space group C2/c, a 39.389(3), b 14.2400(12), c 17.8968(14) Å, β 114.276(3)°, V 9150.7(13) Å3, Z 8]. The detailed crystallog. data were deposited at the Cambridge Crystallog. Data Center as supplementary publication number CCDC 955735. In the experiment, the researchers used many compounds, for example, 4,5-Diiodo-1H-imidazole (cas: 15813-09-9Synthetic Route of C3H2I2N2).
4,5-Diiodo-1H-imidazole (cas: 15813-09-9) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Synthetic Route of C3H2I2N2
