In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1122-28-7, name is 4,5-Dicyanoimidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C5H2N4
Example 19 2-Bromo-4,5-dicyanoimidazole (21) STR67 To 1.18 g (10 mmol) 4,5-dicyanoimidazole and 25 ml 0.1M NaOH was added 1.8 ml Br2 (35 mmol). The mixture was stirred overnight at room temperature and then acidified with dilute HCl. The solid was filtered, rinsed with water and recrystallized from water to give 1.5 g of dicyanobromoimidazole 21 (yield 76.4%).: m.p. 147-149 C. (lit. 141-143 C.); Rf=0.65 (ethyl acetate_methanol=4:1); MS(EI): 198([M+2], 96%), 196 (?M+!, 100%),171 (28.5), 169 (29.2), 117 (27.4), 91 (19.0), 64 (20.6), 53 (22.4), 38 (18.8).
The synthetic route of 1122-28-7 has been constantly updated, and we look forward to future research findings.
