Reaction Conditions

Reaction Steps

Trimethylchlorosilane (20.5 g, 190 mmol) is dissolved in 30 mL of tetrahydrofuran. The solution is suspended with sodium (6.50 g, 283 mmol) and then refluxed at 80° C. Under the argon atmosphere, trimethylsilylacetate (3.12 g, 23.6 mmol) in 20 mL of tetrahydrofuran is added via a syringe for an hour and then the solution is refluxed for another 30 minutes. Then, precipitated inorganic residue is filtered and solvent is removed under vacuum. Remained oil is separated by vacuum distillation to give 1,1-bis(trimethylsilyl)ethanol (yield: 55%). b.p. 110° C. (24 mmHg).
