Experiment: Natural Products and Organometallic Chemistry

Synthesis of Ferrocene from Diacetylferrocene

Materials:
  • Diacetylferrocene (0.50 g, 1.76 mmol)
  • Potassium hydroxide (KOH) (0.10 g, 1.76 mmol)
  • Methanol (25 mL)
  • Water (10 mL)
  • Hexanes (for recrystallization)
  • Ice bath (for cooling)
Procedure:
  1. In a round-bottom flask, dissolve diacetylferrocene in methanol.
  2. Add a solution of KOH prepared by dissolving KOH in water to the flask. Ensure the KOH is completely dissolved before adding to the diacetylferrocene solution.
  3. Heat the reaction mixture to reflux for 30 minutes using a reflux condenser.
  4. Cool the reaction mixture in an ice bath to room temperature.
  5. Pour the reaction mixture into ice water (approximately 100 mL). This will precipitate the ferrocene.
  6. Filter the precipitate using vacuum filtration. Wash the solid thoroughly with cold water.
  7. Purify the crude ferrocene by recrystallization from hexanes.
Key Concepts:
  • The reaction proceeds via nucleophilic attack of hydroxide (OH-) from KOH on one of the carbonyl groups of diacetylferrocene, forming an enolate intermediate.
  • Further reaction leads to the reduction of the carbonyl group and formation of the ferrocene ring system.
  • Recrystallization from hexanes removes impurities and increases the purity of the ferrocene product.
Significance:
  • This experiment demonstrates a reduction reaction in organometallic chemistry.
  • The synthesis of ferrocene highlights the versatility of organometallic compounds.
  • Ferrocene has wide applications in catalysis, materials science, and medicine. Its unique properties stem from the organometallic iron-carbon bond.
Safety Precautions:
  • Wear appropriate safety glasses and gloves throughout the experiment.
  • KOH is corrosive. Handle with care and avoid contact with skin and eyes.
  • Methanol is flammable. Keep away from open flames.
  • Dispose of chemical waste properly according to your institution's guidelines.
