50548-45-3, A common compound: 50548-45-3, name is 1-Bromodibenzo[b,d]furan, belongs to bromides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
500ml round bottom flask reactor1-Bromo-dibenzofuran (20.0g, 0.081mmol), Bis (pinacolato) diboron (26.7g, 0.105mol),[1,1′-bis (diphenylphosphino) ferrocene] palladium in a Dijk (1.3g, 0.002mol),Potassium acetate (19.9g,0.202mol), into a 1,4-dioxane 200ml were stirred for 10 hours under reflux. After the completion of the reaction was filtered a pad of Celite. femaleAfter concentration under reduced pressure they were separated by liquid column and recrystallized with dichloromethane-heptane to give a (17.0g, 70%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Bromodibenzo[b,d]furan, other downstream synthetic routes, hurry up and to see.
