Synthetic Route 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.
0.21 g of palladium(II) acetate, xylene (20 mL), and 0.76 g of tri-tert-butylphosphine were added.Stirred at 60 °C for 30 minutes. The above solution was added to a flask heated to 60°C under nitrogen to give the above compound 4 (16,18-Dihydrobenzo[4,5]furo[3,2-a]benzofurano[2′,3′:6,7]indolo[3,2-h]carbazole 7.4 g), 4-(4-bromophenyl)dibenzo[b,d]furan (13.2 g) and sodium tert-butoxide 5.2 g (54 mmol) were added to the above solution together with xylene (180 mL). Then, it heated up at 130 °C , and it heat-stirred for 6 hours. After cooling to room temperature, 200 mL of water was added. After the organic layer was extracted with chloroform, the organic layer was dried over MgSO4 , the solvent was removed, and silica gel column chromatography was performed, whereby Compound A-10 (6.4 g, 41percent) was obtained.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-(4-Bromophenyl)dibenzo[b,d]furan, its application will become more common.
