| Abstract: | 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. |
