| Abstract: | 2-Bromofluorenone was prepared from fluorene by bromination and oxidation.The optimum oxidation reaction conditions were:THF as solvent,m(2-bromofluorene)∶m(THF)=1∶5.5,n(2-bromofluorene)∶n(KOH)=10∶1 and reaction time 5 h.Yield of 2-bromofluorenone reached 98.0%,with purity higher than 98.0%.Structures of the products were characterized by IR and NMR spectra. |
