Reaction Steps

A solution of (3,5-dibromophenyl)triphenylsilane (2.20 g, 4.45 mmol), 4,4,5,5-tetramethyl-2-(triphenylen-2-yl)-1,3,2-dioxaborolane (3.15 g, 8.90 mmol), Pd(PPh3)4 (0.051 g, 0.045 mmol) and K2CO3 (1.23 g, 8.90 mmol) in toluene (100 mL) and water (20 mL) was refluxed under nitrogen overnight. After cooling to room temperature, the organic phase was isolated, filtered through a short plug of Celite® and the solvent was evaporated. The residue was purified by column chromatography on silica gel with hexane/DCM (7/3, v/v) as eluent followed by recrystallization from the same solvent to yield (3-bromo-5-(triphenylen-2-yl)phenyl)triphenylsilane (1.50 g, 52%) as a white solid.
