摘　　要：以邻二溴苯为原料,与正丁基锂反应制得2,2′-二溴联苯,再与四氯化硅反应得到螺硅双芴,经硝化、还原、重氮化和溴代得到了标题化合物,并通过核磁共振、质谱确定了其结构。The synthesis of 2,2＇-dibromo-9,9＇ -spiro-9-silabifluorene was studied using 1,2-dibromobenzene as the starting matetial. Firstly, 2,2＇-dibromobiphenyl was prepared from 1,2-dibromobenzene, then 9,9＇-spiro-9-silabifluorene was obtained by the reaction of 2,2＇-dibromobiphenyl with SiCl4, and the final product was synthesized via nitration, reduction, diazotization and bromination. The structure of target product was characterized by ^1HNMR and MS.
