To a solution of 2-(2,3,4,5-tetramethylcyclopentadienyl)benzaldehyde (10.0 mmol) in ethanol (60.0 mL) was added dropwise pentafluorophenylhydrazine (11.0 mmol) under a nitrogen atmosphere. The mixture was stirred at room temperature for 2 hrs. The solvent was distilled off under reduced pressure and the residue was recrystallized from hexane to give 2-(2,3,4,5-tetramethylcyclopentadienyl)benzaldehyde pentafluorophenylhydrazone (4.00 g, yield 97.0%).
