• Resumen

  • The synthetic sequence involving the oxidation of fluorene to fluorenone and the reduction of fluorenone to fluorenol can be extended by preparing the title compounds via the intermediate 9-chlorofluorene. The latter is obtained by heating fluorenol in methanol with conc. hydrochloric acid.
