Treatment of Fe(OAc)2in THF with 2 equiv of Li(CPh3) at −25 °C results in the formation of [Fe(η5-CPh3)2] (1) in 22% yield. Complex1was characterized by X-ray crystallography, NMR spectroscopy, and57Fe Mössbauer spectroscopy and features an η5binding mode of its trityl ligands. Complex1functions as an effective Fe(0) synthon. For example, the reaction of1with excess CO results in the formation of [Fe(CO)5] and Gomberg’s dimer. Additionally, thermolysis of1with 5 equiv of P(OMe)3results in formation of the Fe(0) complex [(μ,η4:η4-Ph2CC6H5C6H5CPh2){Fe(P(OMe)3)3}2] (2), which features the novelo,o-isomer of Gomberg’s dimer bound by two [Fe0(P(OMe)3)3] fragments via η4interactions.
