Use
2-bromofluorene is often used as synthetic intermediate of the OLED material in industry, by the reaction of barbier-type ultrasonic radiation, 2-bromofluorene is also used to study the conversion of aryl bromides to aryl triethoxy silane. Lab Preparation Methods: propylene carbonate is used as solvent, N-bromosuccinimide (NBS) is used as brominated reagent to carry bromination reaction of fluorine, and this reaction can synthesize 2-bromofluorene and 2,7-dibromofluorene. By the investigation of reaction temperature, NBS amount, the adding methods, the optimal reaction conditions for the synthesis of 2-bromofluorene is confirmed. The optimal reaction conditions are: reaction temperature is 23℃, the molar ratio of NBS with fluorine is 1.1:1, NBS is added by stage addition. First fluorene and propylene carbonate is preheated to 60℃, so fluorine is all dissolved, and then it drops to the reaction temperature, NBS is added by stage addition. 2-bromofluorene and 2,7-dibromofluorene recrystallizes with ethanol and acetic acid respectively, the purity of target product of liquid chromatography can reach more than 99%.
