Chad introduces silyl ethers (trimethyl silyl ethers specifically) as protecting groups for alcohols. He first explains why and when an alcohol protecting group might be needed and provides an example. He then shows the mechanism for formation of a silyl ether and the removal of it using TBAF (tetrabutylammonium fluoride).
