Adding a certain compound to certain chemical reactions, such as: 36282-26-5, name is 2-Bromo-4-fluorobenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 36282-26-5, COA of Formula: C7H3BrFN
To a solution of 2-bromo-4-fluorobenzonitrile (5.0 g, 25.0 mmol) in anhydrous THF (20 mL) is added PrMgCl 2.0M in THF (15.0 mL, 30.0 mmol) at -30C. The solution is stirred at -30 C for 3 hours and DMF (5.80 mL, 75.0 mmol) is added. The reaction mixture is allowed to warm to room temperature and is stirred for 1 hour. The solution is cooled to -10C, 2M hydrochloric acid (37 mL) is added and the solution is stirred for 20 minutes. The solution is concentrated in vacuo to -1/3 original volume and extracted into EtOAc (3x). The combined organics are then dried (Na2S04), filtered and concentrated to afford 4-fluoro-2-formyl benzonitrile (3.9 g, 71%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Bromo-4-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.
