Related Products of 955959-84-9, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 955959-84-9 name is 4-(4-Bromophenyl)dibenzo[b,d]furan, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Under argon atmosphere, 8 · 31g (10mmol) of Intermediate B-1, 6.46g (20mmol) 4- (4-bromophenyl) dibenzofuran, 0.28g (0.3mmol) of tris (dibenzylideneacetone yl) dipalladium, 0.174 g (0.6 mmol) of tri-tert-butylphosphine tetrafluoroborate and 3.8g (20mmol) sodium tert-butoxide into the three-necked flask, followed by addition of 50ml of dry xylene was heated under reflux for 8 hours The Cooled to 50 ° C, filtered through celite / silica gel, and the filtrate was concentrated under reduced pressure. The resulting residue was purified on a silica gel column and then recrystallized from toluene to give 6.48 g of solid, which was compound BS1 in a yield of 78percent.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-(4-Bromophenyl)dibenzo[b,d]furan, and friends who are interested can also refer to it.
