Description and Uses

Silylating reagent for the protection of 1? and 2? alcohols and N-silylation of amines and amides; used in the preparation of thexyldimethylsilyl triflate; formation of α-silyl hydrazones; formylation of polyfluoroalkyl halides. Thexyldimethylsilyl chloride (TDS-Cl) was first introduced as a more easily prepared alternative to the more commonly used t-butyldimethylsilyl chloride for the protection of alcohols.
