Procedure

Into a suspension of 2-bromotriphenylene (7.28 g, 23.70 mmol) in ether (50 mL) was added n-butyllithium solution in hexane (14.81 mL, 23.70 mmol) dropwise at −78° C. The suspension was gradually warmed to 0° C. and stirred for 3 hours to yield a solution of triphenylenyllithium. In a separate flask a solution of 3-bromophenyllithium was prepared by dropwise addition of n-butyllithium solution in hexane (14.81 mL, 23.70 mmol) into a solution of 1,3-dibromobenzene (2.87 mL, 23.70 mmol) in ether (50 mL). The solution was stirred at this temperature for 2.5 hours before being transferred into a solution of dichlorodiphenylsilane (4.88 mL, 23.70 mmol) in ether (30 mL) at −78° C. After stirring for another 2 h, the triphenylenyllithium solution prepared above was introduced dropwise into the flask containing the dichlorophenylsilane. The reaction mixture was allowed to gradually warm to room temperature and was stirred overnight. The mixture was quenched with water and the organic phase was isolated. Upon evaporation of the solvent, the residue was purified by column chromatography on silica gel with hexane/DCM (85/15, v/v) as eluent to yield (3-bromophenyl)diphenyl(triphenylen-2-yl)silane (8.5 g, 75%) as a white powder.
