| Abstract: | Anionic hydrides of iron-carbonylates have provided synthetic entry to a series of simple, mono-functional iron thiolate and selenate complexes: REFc(CO)₃L-(E=S, Se; R=Ph, MemEt, Ch₂Ph, H; L=CO, P(OEt)₃, PEt₃). Both the metal center and the chalcogen atom of the thiolate or selenate ligand provide sites for reactivity with electrophiles such as R⁺ and H⁺. New thioether, thiol, and thiolate hydride complexes of iron have resulted from such reactivity studies. These complexes have been characterized by nuclear magnetic resonance and infrared spectroscopies. The protonation of MeSFe(CO)₃L-(L=PEt₃ and P(OEt)₃) at -78°C led to a species whose spectroscopic properties are consistent with an n²-RSH coordination to Fe(0), or an "arrested" oxidative addition. On warming the PEt₃ derivative to -20°C, conversion to the Fe(II) hydridothiolate occurred prior to decomposition into H₂ and dimeric Fe(I) complexes. |
