Versuchsvorschrift

To a slurry of sodium acetate (8.2 g, 100 mmol, 2.0 equiv.) in anhydrous diethyl ether (40 mL) was slowly added a solution of dimethyldichloro silane 11A (6.45 g, 50 mmol, 1.0 equiv.) in anhydrous diethyl ether (10 mL). After addition was completed, the mixture was heated at reflux for 2 hours, and then filtered under N2. The filtrate was concentrated under vacuum at 40° C. to give diacetate 11B as a colorless oil (6.1 g, 70%).
