| titleOfInvention | Method for synthesizing bromo-fused ring aromatic compound |
| abstract | The invention discloses a method for synthesizing bromo-condensed ring aromatic compounds, which is characterized by comprising the following steps: the method comprises the following steps: taking a polycyclic aromatic hydrocarbon compound as a substrate, adding alkali metal bromide, slowly adding ZnAl-BrO into a mixed solution of water and an organic solvent 3 Reacting for 4-8 h at 20-35 ℃ by using LDHs, tracking the reaction process by using TCL, washing the reaction mixture by using a sodium sulfite solution after the reaction is finished, extracting by using dichloromethane, combining organic phases, concentrating under reduced pressure to obtain a crude product, and finally adding petroleum ether: and (3) taking ethyl acetate as an eluent, and separating by column chromatography to obtain the monobromo or dibromo polycyclic aromatic hydrocarbon compounds respectively. The brominating reagent used in the invention is a solid substance, is cheap and easy to obtain, and is environment-friendly; the reaction condition is mild; the post-treatment is convenient, and the reaction operation is simple; the atom utilization rate and the selectivity are high; high yield of target product and less side reaction. |
