Procedure

56.8 parts of fluorene, 200 parts of methanol, 37 parts of 63% sulfuric acid aqueous solution, 31 parts of iodine, and 34 parts of 34% iodic acid aqueous solution were stirred at 60° C. for 5 hours. After completion of the stirring, the resultant was filtrated, and it was then washed with 100 parts of water twice. Thereafter, the resultant was dried at 70° C. overnight. After completion of the drying, the resultant was recrystallized in methanol to obtain 60 parts of 2-iodofluorene in the form of white powders.
