二乙氧基二甲基硅烷

反应条件: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 306 mg of allyl chloride, 530 mol of dimethyldiethoxysilane, and 77 mg of toluene were placed in a glass reaction tube. Then, 0.005 mol of a toluene solution of a 0-valent platinum complex of divinyltetramethyldisiloxane (platinum content: 0.4 wt %) was added to this mixture. The reaction tube was sealed and heated for 2 hours in an oil bath at 50° C. When the contents were analyzed by GC-MS following cooling, the conversion rate of allyl chloride was 100% and γ-chloropropylmethyldimethoxysilane was produced at a yield of 19.7%. The reaction tube was sealed following cooling

实验步骤: 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%.
