실험 절차

27.5 g (417 mmol) of freshly distilled cyclopentadiene are added dropwise to a solution of 167 ml of n-butyllithium (2.5 molar) (417 mmol) in 250 ml of absolute tetrahydrofuran at RT over a period of one hour. 71.11 g of (chloromethyl)trimethoxysilane are subsequently added dropwise over a period of 30 minutes. The solution becomes warm during this process. After taking off the solvent, the mixture is fractionally distilled under reduced pressure to give 72.2 g of (cyclopentadienylmethyl)trimethoxysilane (yield: 93%).
