실험 절차

As depicted in Reaction 2, a solution of 4 g (17 mmol) of dibromobenzene in ether was cooled. To the solution were sequentially added n-BuLi and chlorotriphenylsilane. The mixture was allowed to react at room temperature. After completion of the reaction, the reaction mixture was extracted with ether. After the solvent was removed under reduced pressure, the residue was purified by column chromatography to give the title compound. The product was collected by filtration under reduced pressure and dried. Yield: 66%. 1H-NMR (CDCl3, ppm): 7.54-7.5 (m, Ar—H), 7.45 (Ar—H), 7.40-7.35 (m, Ar—H). IR (KBr, cm−1): 1568, 1477-1376, 1110, 810, 727, 698. MS (EI) (Calcd. for C24H19BrSi: 414. Found: 414).
