variable quantities of (C5H5)Fe(CO)S2CNHCH3 are obtained depending on reaction conditions. The carbamoyl derivatives (C5H5Re(CO)(NO)CONHCH3, cis-(CO)4M(NH2CH3)CONHCH3 (M = Mn, Re) react with CS2 to give (C5H5)Re(CO)(NO)S2CNHCH3 and (CO)4MS2CNHCH3 respectively. The mechanism of thiocarbamate formation is discussed on the basis of chemical evidence which indicates nucleophilic attack of the N-carbamoylic
