Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 116632-39-4, name is 5-Bromo-2-iodotoluene, A new synthetic method of this compound is introduced below., Application In Synthesis of 5-Bromo-2-iodotoluene
4-Bromo-1 -iodo-2-methylbenzene, 5.00 g (16.8 mmol), and N-bromosuccinimide, 3.06 g (20.2 mmol), were dissolved into 50 mL of 1,2-dichloroethane. 2,2′-Azobisisobutyronitrile, 0.28 g (1.7 mmol), was added to the above solution at 85C and the resulting mixture was stirred at this temperature for 3 hours under nitrogen atmosphere. The solvent was removed in vacuo and the residue was purified by silica gel column chromatography to give 3.01 g (48%) of the product as a white solid. 1H-NMR (400 MHz, CDCI3): delta [ppm] = 4.54 (s, 2H), 7.13-7.16 (m, 1H), 7.63 (d, 1H), 7.73 (d, 1H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
