Abstract
Mild and convenient method for deprotection and direct oxidative deprotection of silyl ethers to the corresponding hydroxy and carbonyl compounds is described using polyvinylpolypyrrolidone-bromine complex (PVPP-Br2). Selective oxidative deprotection of benzylic silyl ethers in the presence of primary aliphatic alcohols was also achieved at room temperature. Keywords: Polyvinylpolypyrrolidone, PVPP-Br2, deprotection, oxidative deprotection, TMS ethers, TES and TBDMS ethers
