2,6-Dibromoanthraquinone - Reference Information
| Application | 2, 6-dibromoanthraquinone is an organic raw material, which can be widely used in the preparation of organic light-emitting materials. |
| preparation | 2, 6-dibromoanthraquinone can be prepared from 2, 6-diamino-9, 10-anthraquinone was prepared after diazotization reaction. 2, 6-diamino-9, 10-anthraquinone (5g,20.99mmol), tert-butyl nitrite (6.20ml,52.00mmol), Copper bromide (11.72g,52.50mmol) acetonitrile (300ml) was added to the reaction flask and reacted for 2H at 65 °c. 20% hydrochloric acid was added for quenching and the precipitate was filtered and washed with dichloromethane and brine. Recrystallization from 1, 4-dioxane gave 2, 6-dibromoanthraquinone (2.44g,30%). 1H NMR(400MHz,CDCl3): Δ8.44 (d,J = 1.2Hz,2H),8.17(d,J = 5.2Hz,2H),7.94(dd,J = 1.2,1.6Hz,2H). |
