Reaction Conditions:
with tetrakis(triphenylphosphine) palladium(0);potassium carbonate in toluene; for 12 h;Inert atmosphere;Reflux;
Steps:
6 Synthesis of Compound 6-1
The compound benzothiophene-4-boronic acid (11.48g, 50mmol) and 3-bromocarbazole (9.76g, 50mmol) were added to a three-necked flask, stirred and dissolved with 200 mL of toluene, protected with nitrogen, and then Pd (PPh3) was added. 4 (2.82 g, 2.5 mmol) and 50 mL of an aqueous solution of K2CO3 , and then the mixture was stirred and refluxed for 12 hours.After cooling, the organic phase was washed three times with 100 mL of water and dried over anhydrous sodium sulfate.Then the solvent is removed by evaporation.The residue was recrystallized from EA/PE.The white solid was obtained as Compound 6-1 (15.75 g, yield 90%).
