文摘

To provide the mechanistic information of nitrogenase at a molecular level, much effort has been made to develop synthetic metal complexes that have enzyme-like reactivity. Herein we obtain an iron(II) complex binding with a tris(thiolato)phosphine ligand, [P(Ph)₄][Fe(PS3鈥?(CH₃CN)] [1; PS3鈥?= P(C₆H₃-3-Me₃Si-2-S)₃^{3鈥?/sup>] that catalyzes the reduction of hydrazine, an intermediate and a substrate of nitrogenase. The substrate- and product-bound adducts, [N(Bu)₄][Fe(PS3鈥?(N₂H₄)] (2) and [N(Et)₄][Fe(PS3鈥?(NH₃)] (3), respectively, are also synthesized. This work provides the feasibility that the late stage of biological nitrogen fixation can be conducted at a single iron site with a sulfur-rich ligation environment.}
