A simple protocol for the deprotection of 1,3-dithianes and 1,3-dithiolanes showed tolerance for a number of phenol and amino protecting groups 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 without any detectable overoxidation.
