What is tert-Butyltrichlorosilane?
The Uses of tert-Butyltrichlorosilane
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.
