反応手順
20 g of diethyleneglycol is added to 9.05 g of sodium hydride in 320 cm3 of tetrahydrofuran, the reaction medium is agitated for 45 minutes, 28.3 g of dimethylterbutylsilane chloride is added, agitation is carried out for 3 hours while leaving the temperature to return to ambient. Extraction is carried out with ether, followed by washing with an aqueous solution of sodium bicarbonate, with salt water, drying and evaporating the solvent. 40.25 g of expected product is obtained.
