| titleOfInvention | A kind of preparation method of high-purity 2- bromine fluorenes |
| abstract | A kind of preparation method of high-purity 2- bromine fluorenes, the invention belongs to the technical fields of organic synthesis, react preparation 2- bromine fluorenes using 2- aminofluorene and hydrobromic acid as raw material, hydrobromic acid and 2- aminofluorene are placed in reactor, stirred, heating, after back flow reaction 2-3h, it is cooled to 40-60 DEG C, cuprous compound is added, after mixing evenly, nitrous acid category compound is added dropwise, it drips off rear insulation reaction 1-2h, toluene dissolved product is added, by filtering out salt, liquid separation, washing, concentration of organic layers obtain 2- bromine fluorenes.Preparation method of the present invention is simple, and reaction process is mildly stablized, and directly obtains 2- bromine fluorenes through one kettle way, obtained 2- bromine fluorenes high income, purity is high. |
