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.[1][2]

Application

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.[3]
