[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
