Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 2050-47-7, name is 4,4′-Oxybis(bromobenzene), This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 4,4′-Oxybis(bromobenzene)
All manipulations were performed under an inert atmosphere of nitrogen. A Schlenk flask equipped with a condenser was charged with 4- bromophenylether (3.90 g), carbazole (4.34 g), 18-crown-6 (0.70 g), Cu (1.65 g) and K2CO3 (3.60 g) and 1, 2-dichlorobenzene (150 mL). The resulting mixture was heated to 180 C for four days. After cooling to room temperature, water was added and the mixture was stirred overnight. The organic layer was isolated and the water layer was washed with water. The combined organic layers were dried over MgSO4 and the solvent was evaporated to give a brown oil. The desired product was isolated by crystallization from CH2CI2/MeOH to give an off-white powder in 58% yield (3. 5 g) 1H NMR (CD2CI2, 500 MHz): 6 8.14 (d, 1H), 7. 58 (d, 1H), 7.42 (m, 2H), 7.35 (d, 1H), 7.27 (m, 1H).
According to the analysis of related databases, 2050-47-7, the application of this compound in the production field has become more and more popular.
