Versuchsvorschrift

To a solution of 2-methylbut-3-yn-2-ol (140 g, 1.67 mol) was added DMAP (20 g 0.17 mol), Et3N (927 ml, 3.33 mol) and TMS-Cl (289 g, 2.66 mol) at 5 degree under a nitrogen atmosphere. After being stirred one hour, the mixture was washed with water, dried (MgSO4), filtered, concentrated, and distilled to obtain trimethyl[(2-methylbut-3-yn-2-yl)oxy]silane (150 g, 0.96 mol).
