Application of 16681-56-4, 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. 16681-56-4, name is 2-Bromo-1H-imidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
To 7.3 g (50 mmol) of 2-bromo-1H-imidazole, 11.1 g of 9-anthracene boronic acid(50 mmol) and 3.5 g (5 mmol) of bistriphenylphosphine palladium dichloride were added 130 ml of 2M aqueous sodium carbonate solution, 260 ml of methylBenzene and 86 ml of ethanol at 100 C for 12 hours. After the system had cooled down, extract with methylene chloride and wash with distilled waterThe organic phase is then washed with anhydrous magnesium sulfate and the solvent is evaporated to dryness. Column chromatography (n-hexane: dichloromethane = 20: 1)Purification gave 8.43 g of intermediate A-1.
The synthetic route of 2-Bromo-1H-imidazole has been constantly updated, and we look forward to future research findings.
