WebOpen Gateway Article This Open Anreise Related is licensed under a Get Commons Attribution-Non Mercantile 3.0 Unported Licence Silyl ethers are a group of chemical compounds which contain a silicon atom covalently bonded to an alkoxy group. The general structure is R R R Si−O−R where R is an alkyl group or an aryl group. Silyl ethers are usually used as protecting groups for alcohols in organic synthesis. Since R R R can be combinations of differing groups which can be varied in order to provide a number of silyl ethers, this group of chemical compounds provides a wide spectrum of selectivity for protecting …
