Versuchsvorschrift

A solution of ferrocene (2.63 kg, 14.2 mole) and 3-chloropropionyl chloride (1.8 kg, 15.6 moles) in dry dichloromethane (23.5 l) was cooled to -3° and treated over 1 hour with aluminium chloride (2.08 kg, 15.6 mole). The reaction mixture was left to stir for 2 hours. To this was then added ice water (30 kg) and the two layers separated. The aqueous layer was washed with dichloromethane and the combined organic liquors were washed with water (30 l), 2% aqueous sodium bicarbonate solution (20 l) and water again (60 l). The organic liquors were then dried and concentrated affording black/brown semi-solid chloropropionyl ferrocene (3.5 kg).
