Application of 955959-84-9, These common heterocyclic compound, 955959-84-9, name is 4-(4-Bromophenyl)dibenzo[b,d]furan, its 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.
To a 250 mL round bottom flask was added D1 (1.80 g, 10.64 mmol),G3 (3.78 g, 11.70 mmol), Tris (dibenzylideneacetone) dipalladium (0) (0.15 g, 0.16 mmol),(BINAP) (0.20 g, 0.32 mmol) and sodium tert-butoxide (1.43 g, 14.89 mmol) were added to a solution of (¡À) -2,2′-Bis (diphenylphosphino) -1,1′- binaphthaleneAfter dissolving in toluene (100 mL)After stirring for 24 hours at 100 C in a bath, when the reaction is completeToluene was removed, and the residue was extracted with dichloromethane and water. The residue was subjected to vacuum distillation. The residue was subjected to silica gel column, and the solvent was distilled off under reduced pressure to obtain Compound G4 (3.05 g, 7.41 mmol).
Statistics shows that 4-(4-Bromophenyl)dibenzo[b,d]furan is playing an increasingly important role. we look forward to future research findings about 955959-84-9.
