실험 절차

A solution of (3,5-Dibromophenyl)triphenylsilane (4.27 g, 8.64 mmol), 2-(3-(dibenzo[b,d]furan-4-yl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1.6 g, 4.32 mmol), Pd(PPh3)4 (0.100 g, 0.086 mmol) and K2CO3 (1.792 g, 12.96 mmol) in toluene (100 mL) and water (10 mL) was refluxed under nitrogen overnight. 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 (4/1 to 3/1, v/v) as eluent to yield (5-Bromo-3′-(dibenzo[b,d]furan-4-yl)[1,1′-biphenyl]-3-yl)triphenylsilane (1.3 g, 45%) as a white solid.
