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. 101-55-3, name is 1-Bromo-4-phenoxybenzene, A new synthetic method of this compound is introduced below., Application In Synthesis of 1-Bromo-4-phenoxybenzene
4-bromodiphenyl ether(6.2g, 25.0mmol) Isopropanol pinacol borate (10.3 mL, 50 mmol)Soluble in dry tetrahydrofuran,Cooled to -78C under nitrogen protection.n-Butyllithium (2.5M, 18 mL, 45 mmol) was added dropwise,After completion of the addition, the mixture was stirred for 6 hours and slowly warmed to -40C for 12 hours.The reaction was added to saturated ammonium chloride solution and extracted three times with ethyl acetate.The organic phases were combined and dried over anhydrous sodium sulfate.It was evaporated to dryness by rotary evaporation and purified by column to give 5.4 g of the target compound in a yield of 72%.
The synthetic route of 101-55-3 has been constantly updated, and we look forward to future research findings.
