Abstract:2-Bromofluorene was synthesized by bromination of fluorene and the process conditions were investigated. The product was obtained in 81.9% yield(>98% HPLC)by reaction in carbon tetrachloride at temperature of 0~5℃ for 4 hrs with the molar ratio of fluorine to hydrogen bromide to H2O2=1 to 1.5 to 2. 1H NMR was used for the product structure characterization. |
Key words:2-bromofluorene; fluorene; oxidative bromination |
