3,5-Dibromobenzaldehyde Usage And Synthesis
Description3,5-Dibromobenzaldehyde is a white or beige solid with a melting point of 84-88 °C. Its boiling point and density are estimated to be 287.2±20.0 °C and 1.977±0.06 g/cm3, respectively. It is insoluble in water.
Synthesis1,3,5-tribromobenzene (3.01 g, 9.6 mmol) in diethyl ether (80 mL) was cooled to -78°C followed by the addition of one equivalent of n-BuLi dropwise (2.5 M, 3.8 mL). The reaction was stirred for 30 minutes then DMF (740 µL, 9.6 mmol) was added dropwise to the reaction and stirred at -78°C for one hour. The vessel was then placed in an ice bath and stirred for 30 minutes. A 10% HCl solution (100 mL) was added to quench the reaction followed by CHCl3 (150 mL). The organic layer was collected and the aqueous layer washed with CHCl3 (80 mL). The organic layers where combined and dried over MgSO4 and the solvent removed. The crude product was purified by column chromatography eluting with 10% EtOAc in hexanes. Spectral data for the title compound was not reported in the literature reference. Yield: 1.93 g of the title compound (77%). 1H NMR (CDCl3, 300 MHz): δ = 9.90 (s, 1H), 7.92 (d, 2H), 7.60 (s, 1H); 13C NMR (CDCl3, 75 MHz) δ = 189.3, 139.7, 139.0, 131.37, 124.1; GC-MS [M+H]+ 262.8709, calcd 262.8707
3,5-Dibromobenzaldehyde
Uses 3,5-Dibromobenzaldehyde is a dibrominated benzaldehyde that is a very useful building block for the preparation of a wide range of biologically active compounds such as a antibacterials. The non-AIE active compound 3,5-dibromobenzaldehyde (DBB) could be used as the core to synthesize AIE luminogens, which differs from the traditional synthetic methods that are heavily dependent on the AIE active core. The three obtained DBB derivatives (S1, S2 and S3) displayed typical AIE features in which the quantum efficiencies of the solid film state were much higher than their solution state. The emission of these DBB derivatives could be fine-tuned by varying the substituents on the DBB rings[1].
