   Sammanfattning : The coordination and fundamental transformations of organosulfur compounds to polynuclear metal complexes has been studied as models for possible surface species in industrial HDS processes. Reactions between [Os3(CO)11(NCMe)] and various thiols have been studied by UV-Vis, IR and NMR spectroscopy and all experimental findings indicate that the reactions proceed via a two-step consecutive process involving the intermediate [Os3(CO)11(RSH)], which contains an agostic Os-H-S interaction, and which leads to the formation of the final product [Os3(CO)10(m-H)(m-SR)].
