Potassium Carbonate → (4-Bromophenyl)(4-(dibenzo[b,c]furan-4-yl)phenyl)diphenylsilane

Participants

Reaction Steps

A solution of dibenzo[b,d]furan-4-ylboronic acid (2.60 g, 12.26 mmol), with bis(4-bromophenyl)diphenylsilane (12.12 g, 24.53 mmol), Pd(PPh3)4 (0.283 g, 0.245 mmol) and K2CO3 (5.08 g, 36.8 mmol) in toluene (200 mL) and water (50 mL) was refluxed under nitrogen overnight. After cooling to room temperature, the organic phase was isolated. Upon evaporation of the solvent, the residue was purified by column chromatography on silica gel with hexane:DCM (9:1, v/v) as eluent to yield (4-bromophenyl)(4-(dibenzo[b,c]furan-4-yl)phenyl)diphenylsilane (3.14 g, 44%) as a white solid.
