반응 조건

반응 단계

Dibromofluorene (320 g) prepared previously (as described above) is added to a KOH solution (1-l, 50% w/w) and Aliquat-336 (3 ml) at 85° C. in a 3 l three-necked round bottomed flask equipped with a magnetic stirrer, reflux condenser and dropping funnel. The suspension was heated to 85° C. at which temperature n-octylbromide (500 ml) is added dropwise, to form eventually a two-phase system. Once the addition is complete the reaction is stirred at 85° C. overnight, and then allowed to cool to room temperature. Dichloromethane is then added to the reaction mixture (500 ml).
