実験手順

A solution of (3,5-dibromophenyl)triphenylsilane (4.02 g, 8.12 mmol), 9-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-9H-carbazole (1.500 g, 4.06 mmol), Pd(PPh3)4 (100 mg, 0.086 mmol), K2CO3 (1.123 g, 8.12 mmol) in toluene (100 mL) and water (20 mL) was refluxed under nitrogen for 24 h. After cooling to room temperature, the organic phase was isolated and the solvent was evaporated. The residue was purified by column chromatography on silica gel with hexane/DCM (9/1 to 4/1, v/v) as eluent and recrystallized from hexane/DCM (9/1, v/v) to yield 9-(3′-Bromo-5′-(triphenylsilyl)-[1,1′-biphenyl]-3-yl)-9H-carbazole (2.1 g, 79%) as white crystals.
