An efficient regioselective NBS aromatic bromination in the presence of an ionic liquid was written by Pingali, Subramanya R. K.;Madhav, Monika;Jursic, Branko S.. And the article was included in Tetrahedron Letters in 2010.Synthetic Route of C7H4Br2N2 This article mentions the following:
A simple, efficient, and rapid method was developed for high-yielding regioselective monobromination of activated aromatic compounds using NBS in combination with ionic liquid 1-butyl-1-methylimidazolium bromide ([Bmim]Br) or dioxane. The ionic liquid is recyclable and can be reused with minimal loss in the catalytic efficiency if the ionic liquid is rapidly microwaved prior to reactions. In the experiment, the researchers used many compounds, for example, 2-Amino-3,5-dibromobenzonitrile (cas: 68385-95-5Synthetic Route of C7H4Br2N2).
2-Amino-3,5-dibromobenzonitrile (cas: 68385-95-5) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.Synthetic Route of C7H4Br2N2
