Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 108-37-2, name is 1-Bromo-3-chlorobenzene, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C6H4BrCl
To a solution of diisopropylamine (76 mL, 0.4 mol) in anhydrous THF (664 mL) and n-hexane (220 mL) was added 2.5 M n-BuLi (160 mL, 0.4 mol) dropwise at -78 C. over 1 h. The mixture was stirred for 1 h at -78 C. and a solution of 1-bromo-3-chlorobenzene (76 g, 0.4 mol) in anhydrous THF (300 mL) was added dropwise at -78 C. After stirring for an additional 1 h at the same temperature, a solution of iodine (101 g, 0.4 mol) in anhydrous THF (400 mL) was added dropwise at -78 C. The temperature was raised from -78 C. to rt during 2 h. After stirring for 18 h at rt, the mixture was concentrated in vacuo to give the crude product (120 g) which was distilled under reduced pressure to give 1-bromo-3-fluoro-2-iodobenzene (115 g, 91%). 1H NMR (400 MHz, CDCl3) delta ppm 7.12-7.18 (t, 1H), 7.35-7.41 (dd, 1H), 7.49-7.54 (dd, 1H); MS (E/Z): 317 (M+H+)
According to the analysis of related databases, 108-37-2, the application of this compound in the production field has become more and more popular.
