A simple clean expeditious protocol for the deprotection of 1,3-dithianes and 1,3-dithiolanes has been developed using 30% aqueous hydrogen peroxide activated by iodine catalyst (5 mol%) in water in the presence of sodium dodecyl sulfate (SDS) under essentially neutral conditions. The method showed tolerance for a number of phenol protecting groups such as allyl, benzyl, TBDMS, TBDPS ethers, phenolic
