- Method for synthesizing 4, 4'-bis (9H-carbazole-9-yl) biphenyl compound in one step
-
The invention relates to a method for one-step synthesis of a 4, 4 '-bis (9H-carbazole- 9-yl) biphenyl compound, which comprises the following steps: adding a carbazole compound, a 1, 4-diiodobenzenecompound, organic alkali, a copper salt catalyst, a silver salt oxidant, a phase transfer catalyst and an organic solvent into a reactor, reacting at 120-140 DEG C for more than 12 hours in an air atmosphere, cooling after completion of the reaction, performing organic solvent rotary evaporation, extracting, washing, drying, filtering, performing organic solvent rotary evaporation, and carrying out column chromatography separation to obtain the 4, 4 '-bis (9H-carbazole -9-yl) biphenyl compound. The method provided by the invention realizes one-step synthesis of the product, and has the advantages of high product yield and low preparation cost.
