| Abstract: | Summary. A straightforward and effective procedure for the deprotection of thioacetals to the corresponding carbonyl compounds using
potassium persulfate and the ionic liquid bmim]Br under solvent-free conditions is reported. A variety of aliphatic and aromatic 1,3-dithiolanes or 1,3-dithanes was deprotected
to the corresponding carbonyl derivatives by this procedure. |
