2-bromofluorene usage and synthesis

outline	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%.
uses	(1) it can be used as pharmaceutical intermediate, it is also important intermediate in the synthesis of optoelectronic material. (2) by ultrasonic radiation of barbier-type reaction, 2-bromofluorene is used for the study of aryl bromide (aryl bromides) converts to aryl triethoxysilane (aryltriethoxysilanes). it is also for the preparation of n-carbazole fluorene oligomers end-capped. it can be used as intermediates of oled materials in industry.
chemical properties	white to slightly yellow crystalline powder
