1-フルオロアダマンタン

純化方法Dissolve it in Et2O, dry over Na2SO4, evaporate to dryness and sublime the residue at 90-100o/12mm. Recrystallise the sublimate from MeOH, m 259-260o. To remove 1-hydroxyadamantane impurity, dissolve it in cyclohexane, cool for many hours, filter off the hydroxyadamantane, and evaporate to dryness or by passage through an Al2O5 column in dry cyclohexane. Recrystallise the residue from pet ether at -77o and sublime it in vacuum, m 210-212odec (sealed tube). [Bhandari & Pinock Synthesis 655 1974, NMR: Fort et al. J Org Chem 30 789 1965.]
