-20 °C

In a 1000 ml flame-dried flask equipped with a magnetic stir bar, 250 ml of dry ether and 37 g (250 mmol) of diethoxyldimethylsilane were injected under argon. The solution was vigorously stirred while 250 ml of allylmagnesiumbromide in ether (1.0 M) was added dropewise over 2 hours. The solution was refluxed overnight to complete the coupling reaction. After cooling the mixture to −20° C. and removing the solid by filtration, the solvent was removed by rovaperation. The raw product was subjected to vacuum distillation to obtain 30 g of pure allylethoxyldimethylsilane (colorless liquid) with yield of 84%.
