(3-Bromophenyl)triphenylsilane is used as a material for organic electroluminescent elements, display devices and lighting devices.

1,3-Dibromobenzene 20 g (84.77 mmol) was dissolved in THF 500 mL and then cooled to a temperature of -78. n-BuLi 2.5M 33.9 mL(84.77 mmol) was slowly added thereinto and then stirred at a temperature of -78 for 1 hour. Chlorotriphenylsilane ((C6H5)3SiCl) 29.9 g was dissolved in THF 100 mL, and this solution was added to the above reaction mixture. The resultant mixture was slowly warmed to room temperature and stirred for 12 hours. Then, extraction with EA, wash with distilled water and aqueous NaCl solution, drying over MgSO4, distillation under reduced pressure, and recrystallization with MC-MeOH in the ratio of 1:10, were sequentially performed, thereby obtaining (3-Bromophenyl)triphenylsilane 18 g(95 percent).
