A new and unequivocal method for establishing the position of N-glycosylation of unsymmetrically C-substituted imidazoles was written by Benson, Timothy J.;Robinson, Brian. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1992.COA of Formula: C3H2I2N2 This article mentions the following:
N-Substitution of an unsym. C-substituted imidazole can give rise to a pair of structurally isomeric derivatives and to differentiate between such related compounds can be difficult. Two methods, one spectroscopic and one chem., for ascertaining the orientation of such N-substitutions are described, with particular application to the establishment of the direction of N-ribosidation of a series of halogeno nitroimidazoles. In the experiment, the researchers used many compounds, for example, 4,5-Diiodo-1H-imidazole (cas: 15813-09-9COA of Formula: C3H2I2N2).
4,5-Diiodo-1H-imidazole (cas: 15813-09-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.COA of Formula: C3H2I2N2
