3,7-dibroModibenzo[b,d]furan Chemical Properties,Uses,Production
Uses
3,7-dibroModibenzo[b,d]furan can be used as an organic electroluminescent device material or as a raw material for organic synthesis for the preparation of electronic components and electronic devices.
Synthesis
3,7-dibroModibenzo[b,d]furan is synthesised using 2-methoxy-2'-amino-4,4'-dibromobiphenyl as a raw material by chemical reaction. The specific synthesis steps are as follows:
2-Methoxy-2’-amino-4,4’-dibromobiphenyl (0.9 g, 2.5 mmol) was added to the mixture of H2SO4 (0.65 g, 6.3 mmol) and water (5 mL), and then a solution of sodium nitrite (0.2 g, 2.9 mmol) in water (5 mL) was added slowly to aforementioned mixture at 0 °C. After stirring for 2 h at 0 °C, an excess of urea was added to destroy the unreacted nitrous acid. The reaction mixture was stirred overnight at room temperature, and then stirred for 24 h at 70 °C. After cooling to room temperature, the solid was filtrated and collected. The crude product was purified by column chromatography silica gel with petroleum ether to give a beige solid (3.3 g, 92%). 1H NMR (400 MHz, CDCl3): δ (ppm) 7.78 (d, J = 8.0 Hz, 2 H), 7.74 (d, J = 1.6 Hz, 2 H), 7.49 (dd, J = 8.0, 1.6 Hz, 2 H).![3,7-dibroModibenzo[b,d]furan synthesis](/NewsImg/2024-01-24/6384169239714209493823421.png "3,7-dibroModibenzo[b,d]furan synthesis")
