27.5 g (417 mmol) of freshly distilled cyclopentadiene are added dropwise to a suspension of 15 g (417 mmol) of sodium hydride in 250 ml of absolute tetrahydrofuran at room temperature over a period of one hour. 100.3 g of (3-chloropropyl)triethoxysilane 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 in an oil pump vacuum to give 96.1 g of (3-cyclopenta-dienylpropyl)triethoxysilane (yield: 90%).
