Vorschrift

In an inert atmosphere, 170 mg of PtO2.xH2O (containing 80% of Pt) and 5 mg of anhydrous SnCl2 are introduced into the glass beaker. 120 cm3 of glacial acetic acid and 29.1 g (0.10 mol) of 4-chlorobutyroylferrocene whose main impurities are 1.4% by weight of ferrocene and 0.88% by weight of 1,1'-di(4-chlorobutyroyl)ferrocene are then poured in. This 4-chlorobutyroylferrocene was obtained in the customary manner by a reaction of the Friedel-Crafts type between ferrocene and 4-chlorobutyryl chloride in CH2Cl2 in the presence of AlCl3 as catalyst, followed by recrystallisation of the crude product obtained from hexane.
