Cyclopentadiene → n-Butyl cyclopentadiene

Participants

Reaction Conditions

Reaction Steps

n-Butylcyclopentadiene was prepared analogously to Example 1 and freed or inorganic salts and excess cyclopentadiene. The solution so obtained was cooled to 0° C. and subsequently admixed dropwise with 9.7 g of n-butyllithium (90% strength in hexane; 136 mmol). The mixture was allowed to react for a further 30 minutes while stirring. 15.8 g of ZrCl4 (68 mmol) was added at 0°-10° C. and the mixture was stirred for 2 hours at room temperature.
