Applications: Triisopropylchlorosilane (TIPSCl) can be used as a pharmaceutical intermediate.
Synthesis: In a 1L three-necked flask, 74.17 g (3.09 mol) of magnesium metal and 240 mL of tetrahydrofuran were added. Under nitrogen protection, 376.38 g (3.06 mol) of bromoisopropane was added dropwise at 45–55 °C over approximately 6 hours. The mixture was then kept at 45–55 °C for 30 minutes before use. In a 2L three-necked flask, 164.2 g (0.97 mol) of SiCl4 and 200 mL of tetrahydrofuran were added. Grignard reagent was added dropwise at 0–5 °C. After the addition was complete, the temperature was raised to 50–55 °C and the reaction was maintained for 4 hours. The mixture was then cooled to room temperature, filtered, and the filter cake was washed with a small amount of tetrahydrofuran. The filtrates were combined, and the mixture was distilled. The fraction collected at 82–85 °C/15 mmHg yielded 122 g of a colorless liquid, with a yield of 74%. Chemical Properties: Boiling point 198℃ (739 mmHg).
Uses: Pharmaceutical and organic synthesis intermediate.
Uses: Triisopropylchlorosilane is used as a catalyst in the preparation of (siloxy)cyclobutene derivatives. It is also used in the addition reaction of diethylzinc and N-diphenylphosphonoimide.
