In the presence of hydrogen peroxide and trimethylsilyl chloride, thiocarbonyls desulfurize to the corresponding carbonyls in short reaction times with no side reactions and excellent selectivity. This process is a safe, operationally simple, and environmentally benign alternative for the desulfurization of thiocarbonyls.
