Application

tert-Butyldimethylsilyl chloride (TBDMSCl) is an organosilicon compound that can be used as a versatile protecting reagent for alcohols, amines, amides, and various carboxylic acids. It is also used in the preparation of isoxazoline N-oxides from α-bromonitroalkanes and olefins. TBDMSCl is used as a precursor that forms a silicon substrate for Ag/ZnO/graphene-based nanocomposites to form effective photocatalytic system for hydrogen production.
