摘要

Silyl ethers are traditionally used for the protection of alcohols and are stable in the presence of most nucleophiles, owing to the low leaving-group ability of the siloxy groups.[1] Carbon nucleophiles, such as allylsilanes [2] and enol acetates,[3] can react with silyl ethers in the presence of suitable Lewis acids. Furthermore, the bromination, thiocyanation, and isothiocyantion of silyl ethers in an ionic liquid were also developed.[4] Although azides ...
