Synthesis method
Dissolve phenanthrene in dry carbon tetrachloride, heat to reflux, add bromine dropwise, and continue to reflux to escape the generated hydrogen bromide. The solvent was evaporated from the reaction solution under reduced pressure, and distillation under reduced pressure was continued to collect the 177-190°C (0.16kPa) fraction, which is 9-bromophenanthrene, with a yield of 90%-94%.
Purpose
Used in organic synthesis.
