Versuchsvorschrift

To a suspension of 0.4 g (10 mmol) of potassium hydride in tetrahydrofurane, 1.96 g (10 mmol) of a (3-trimethylsiloxy-propyl)-cyclopentadiene in tetrahydrofurane is added. The reaction is maintained under stirring for 2 hours. Subsequently, the resulting suspension is concentrated to dryness, leaving an oily solid that, when it is washed with hexane, gives a cream-coloured solid. (1.6 g, 7 mmol. Yield:70%).
