Reference of 40422-70-6, 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. 40422-70-6, name is 1-Bromo-3-(2-bromoethyl)benzene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Example 18; 4-Bromo-2-(2-bromo-ethyl)-benzenesulfonyl chlorideChlorosulfonic acid (17 mL) was added dropwise to 1-bromo-3-(2-bromo-ethyl)-benzene (5 g, 19 mmol) at 0 C. The mixture was stirred at 0 C. for 1 h then an additional 3 h at rt. The mixture was poured into an ice-water slowly and extracted with methylene chloride, and the combined organic layers were evaporated under reduced pressure to give 4.3 g of crude 4-Bromo-2-(2-bromo-ethyl)-benzenesulfonyl chloride which was used directly for next reaction. MS (ESI) 342.9 (M-Cl+OH)-.
The synthetic route of 1-Bromo-3-(2-bromoethyl)benzene has been constantly updated, and we look forward to future research findings.
