General procedure for the synthesis of 9-([1,1'-biphenyl]-4-yl)-2-bromo-9H-carbazole from 2-bromocarbazole and 4-iodobiphenyl: To a 1,000 mL round-bottomed flask fitted with a stirrer under nitrogen protection were added 22.22 g (90.3 mmol) of 2-bromocarbazole, 37.94 g (135.5 mmol) of 4-iodobiphenyl, 18.72 g ( 135.5 mmol) potassium carbonate and 400 mL of dimethyl sulfoxide. Subsequently, 3.26 g (135.47 mmol) 1,10-phenanthroline and 1.79 g (18.06 mmol) copper(I) chloride were added dropwise to the reaction system. The reaction mixture was stirred at 150°C for 12 hours under nitrogen atmosphere. After completion of the reaction, distilled water was added to the reaction mass. The resulting solid was dissolved in chlorobenzene, decolorized and dried by adding activated carbon and anhydrous magnesium sulfate. After stirring and filtration, the filtrate was recrystallized with chlorobenzene and methanol to give 25 g (70% yield) of the target compound 9-([1,1'-biphenyl]-4-yl)-2-bromo-9H-carbazole. | [References]
