| | 2,7-Dibromo-9H-fluoren-9-one Usage And Synthesis |
| Chemical Properties | Yellow powder or crystal | | Uses | 2,7-Dibromo-9-fluorenone was used in preparation of :
- 2,7-poly(spiro[4′,4′-dioctyl-2′,6′-dioxocyclohexane-1′,9-fluorene]), precursor polymer for the synthesis of 2,7-poly(9-fluorenone)
- 2,7-dibromo-9-(2-methylpyridin-5-yl)fluoren-9-ol
| | Synthesis | In a 250 mL four-necked flask equipped with a thermometer, reflux condenser tube and mechanical stirring, 12.4 g (77.75 mmol) of bromine, 85 mL of water, 10 g (55.56 mmol) of fluorenone was added with stirring, heated, and the reaction was carried out at 95-100 C for 3 h. The reaction was stopped, and the reaction was cooled to room temperature; the pH of the reaction system was adjusted to neutrality, 9.3 g ( 58.31 mmol) bromine, heated to 95-100 under stirring for 4 hours, stop the reaction, cooled to room temperature; adjust the pH of the reaction system to neutral, add 6.3g (38.87 mmol) bromine, heated to 95-100 under stirring for 4 hours, stop the reaction; cooled, filtration, the resulting solids were washed three times with 30 mL of water, and drying to obtain yellow color. Solid product, yield 98%. |
