摘　　要：以芴、溴素为原料,三氯甲烷为溶剂,室温下合成得到2,7-二溴芴,然后以四氢呋喃为溶剂,在叔丁醇钾作用下与卤代烷烃反应合成目标化合物9,9-二烷基-2,7-二溴芴,总收率为56.0-62.4%.通过1H NMR,13CNMR,MS,IR和元素分析确证了2,7-二溴芴与标题化合物的结构.2,7-Dibromofluorene is synthesized with fluorene and bromine as starting materials in chloroform solution at room temperature,followed by reacting with halogenated bromide in THF solution in the presence of potassium tert-butanolate as the catalyst.The target compound 9,9-dialkyl-2,7-dibromo-fluorene is prepared with its total yield reaching 56.0%-62.4%.The structures of 2,7-dibromofluorene and 9,9-dialkyl-2,7-dibromo-fluorene are determined by 1H NMR,13C NMR,MS,IR and elementary analysis.
