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. 105942-08-3, name is 4-Bromo-2-fluorobenzonitrile, A new synthetic method of this compound is introduced below., Computed Properties of C7H3BrFN
4-Bromo-2-phenoxy-benzonitrile (5c). Sodium hydride (12 g, 300 mmol) (60% by wt) was weighed into a flask and washed free of oil with several hexane rinsings. The hexanes were decanted and discarded and DMF was added to the flask. A solution of phenol (23.5 g, 250 mmol) in DMF (100 ml_) was added dropwise and the mixture was stirred at room temperature. To the mixture was added a solution of 4-bromo-2-fluoro-benzonitrile (50 g, 250 mmol, 100 ml_ DMF), dropwise. Upon complete addition, the reaction was refluxed for 20 h. The reaction was cooled to room temperature and poured into cold 1 N NaOH. A fine, tan precipitate formed and was collected by vacuum filtration to give Compound 5c. MS m/z (MH+) 277.
The synthetic route of 105942-08-3 has been constantly updated, and we look forward to future research findings.
