Transition metal carbonyls desulfurizations

Although of little synthetic interest at the present time, mention must be made of desulfurizations by transition metal carbonyls. Thus thiols and/or sulfides are desulfurized by complexes such as [MofCOIe], [Fe3(CO)i2], [Co2(CO)s] and [Os3(CO)i2]. Coupling desulfurizations of dithioketals have been performed with [W(CO)6] or [Mo(CO)6], and a recent review gives further information about the hydrodesulfurization of thiophenes.
