Abstract
This paper describes the oxidation deprotection of trimethylsilyl ethers, tetrahydrophyranyl ethers and deprotection of ethylene acetals to afford carbonyl compounds using benzyltriphenylphosphonium peroxymonosulfate (1) (PhCH2PPh3HSO5) in the presence of a catalytic amount of bismuth chloride under microwave irradiation. This reagent is a stable white powder, which has been prepared by the dropwise addition of an aqueous solution of benzyltriphenylphosphonium chloride to an aqueous solution of oxone® at room temperature.
