Abstract
TES- and TBS-protected alcohols undergo deprotection upon treatment with excess ZnBr2 and water in CH2Cl2 at 44–50°C. TIPS-protected alcohols also undergo deprotection but at slower rates. TBDPS-protected alcohols and silyl-protected phenols are unreactive under these conditions, allowing for selective deprotection of differentially-protected bis-silyl ethers.
