tert-Butylchlorodiphenylsilane Usage And Synthesis

Chemical Properties	Tert-Butylchlorodiphenylsilane is a colorless to pale brown oily liquid with pungent odor, may be used as silylating agent for derivatization of alcohols, ketones, carboxylic acids, amines, amides and mercaptanes selectively into functional groups in different sterical environments.
Physical properties	colorless liquid, bp 93–95°C/0.015 mmHg; n20 D 1.5680; d 1.057 g cm?3.
Uses	Several newmethods have been developed for using the reagent to protect primary and secondary alcohols as their TBDPS ethers. In the presence of ammonium nitrate or ammonium perchlorate, reaction between TBDPS-Cl and a primary alcohol, such as benzyl alcohol, in DMF provided excellent yields of the corresponding silyl ethers in just 15 min (eq 1).19 When silver nitrate was used as promoter, the reactions gave inferior yields under otherwise identical conditions. When TBDPS-Cl is used to react with hemiacetals, it converts hemiacetals into ring-opened silyl ether carbonyl compounds, instead of mixed acetals.Presumably, the sizable TBDPS group presents too much steric hindrance for the formation of the corresponding mixed silyl acetals.
Uses	tert-Butyldiphenylchlorosilane acts as a silylating reagent used to protect alcohols and in the preparation of silyl ethers. It plays a major role as a raw material and a precursor in organic synthesis and pharmaceuticals. It is also used for the synthesis of interphenylene phenyloxazoles
