tert-Butyltrichlorosilane Chemical Properties,Usage,Production

Uses

Hydrolytic condensation of tert-butyltrichlorosilane (tBuSiCl₃)in DMSO and water was investigated. The process results in the formation of tBu₂Si₂O(OH)₄, the Ti complex of the intermediate produce active heterogeneous epoxidation catalysts.

General Description

tert-Butyltrichlorosilane is a tert-alkyltrichlorosilane that can be prepared by reacting trimethyl chloride and silicon tetrachloride. It can be used in the synthesis of tert-butyl silsequioxanes by hydrolytic condensation in DMSO.
