Application of 955959-84-9,Some common heterocyclic compound, 955959-84-9, name is 4-(4-Bromophenyl)dibenzo[b,d]furan, molecular formula is C18H11BrO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
In the 250 mE rounded-bottom flask, the compound Al (1.80 g, 10.64 mmol), the compound F2 (3.78 g, 11.70 mmol), tris(dibenzylideneacetone) dipalladium(0) (0.15 g, 0.16 mmol), (¡À)-2,2?-bis(diphenylphosphino)-l , 1 ?-binaphthalene(I3INAP) (0.20 g, 0.32 mmol) and sodium tertbutoxide(l.43 g, 14.89 mmol) were dissolved in toluene (100 mE) and stirred in the bath of the temperature of 100 C. for 24 hrs. After the completion of the reaction, toluene was removed, and the resultant was extracted and distilled under the reduced pressure using dichioromethane and water. After the silica gel colunm, the solvent was distilled under the reduced pressure such that the compound F3 was obtained. (3.05 g, 7.41 mmol)
The synthetic route of 955959-84-9 has been constantly updated, and we look forward to future research findings.
