Application
Trimethylsilylating Reagent
Typical Procedure (Entry 1):
In a 100 mL flask equipped with a Dean-Stark trap are placed hexanoic acid (17.5 g, 151 mmol), hexamethyldisiloxane (48.7 g, 301 mmol), sulfuric acid (1.5 g, 15 mmol), and toluene (40 mL). The flask is then heated to gentle reflux, and the course of the reaction is monitored by GLC. After 72 h, the reaction mixture is distilled under reduced pressure to give trimethylsilyl hexanoate (20.2 g, Y. 71%) as a colorless liquid.
