36856-91-4, 2-Bromoquinoxaline is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Under the protection of nitrogen,Weighing compound S5 (15 mmol), S17 (15 mmol), [Pd2(dba)3]¡¤CHCl3(0.3 mmol) and HP(tBu)3¡¤BF4 (0.6 mmol),Add to a 100 mL two-necked flask.Inject 30 mL of toluene into the two-necked flask (pre-pass N2 for 15 min to remove oxygen).Then, 3.6 mL of a 1 M aqueous solution of K2CO3 (previously passed N2 for 15 min to remove oxygen) was added dropwise, and stirred at room temperature overnight.After the reaction was over, 50 mL of deionized water was added.Then add a few drops of 2M HCl. Extract with dichloromethane.Collect organic phase,It was dried over anhydrous Na2SO4.Filter the dried solution,The solvent was removed using a rotary evaporator to give a crude material.The crude product was purified by silica gel column chromatography.Final purification gave solid P4 (13.2 mmol, 88%)., 36856-91-4
As the paragraph descriping shows that 36856-91-4 is playing an increasingly important role.
