In the presence of hydrogen peroxide and trimethylsilyl chloride, thiocarbonyls desulfurize to the corresponding carbonyls. The safe, operationally simple, general reaction gives excellent yields in short reaction times with no side reactions and excellent regioselectivity, which makes this process an attractive, environmentally benign alternative for the desulfurization of thiocarbonyls. protecting

Silvercarbonate supported on celite (Ag2CO3/Celite) is used as a mild heterogeneous reagent for conversion of variety of thioamides into their corresponding amides in acetonitrile at room temperature. We thank the Razi University Research Council for financial assistance.
The hydrogen peroxide/zirconium(IV) chloride reagent system has been used as a new and efficient reagent for the deprotection/desulfurization of thioamides to amides. This system is reasonably general and can be applied to the conversion of several thioamides to the corresponding amides. The salient features of this protocol are short reaction times, good chemoselectivity, cleaner reaction profiles
