Application of 1435-50-3, 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. 1435-50-3, name is 2-Bromo-1,4-dichlorobenzene belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
4-Bromo-2,5-dichloronitrobenzene A solution of 2-bromo-1,4-dichlorobenzene (1.000 g, 4.443 mmol, Aldrich, used as received) in fuming HNO3 (7.0 mL) was stirred at 50 C. for 1.5 h and poured into ice (80 g). The yellowish precipitate was filtered, washed with water (10 mL) and dried under vacuum to give 1.14 g (95%) of pure title compound as a yellowish powder; m.p. 50-53 C.; 1 H NMR (CDCl3):7.863 (s, 1H), 8.030 (s, 1H).
The synthetic route of 2-Bromo-1,4-dichlorobenzene has been constantly updated, and we look forward to future research findings.
