588-96-5, A common heterocyclic compound, 588-96-5, name is p-Bromophenetole, molecular formula is C8H9BrO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: b.Cyanation of aryl bromides. To a solution of arylbromide (0.5 mmol) in EtOH (5.0 mL) was added NCTS (272 mg, 1.0 mmol), PdCl2 (13.3 mg, 0.075 mmol), and Ag2O (57.75 mg, 0.5 mmol). The mixture was stirred at 70 for 24 hunder air atmosphere. Then the reaction mixture was cooled to room temperature and filtered through a pad of celite (1.0 g) and rinsed with CH2Cl2 (10.0 mL). The resulting organic solution was concentrated under reduced pressure and further purified by flash chromatography (SiO2,petroleum ether/EtOAc gradient), yielding the corresponding aryl nitriles.
The synthetic route of p-Bromophenetole has been constantly updated, and we look forward to future research findings.
