我们报告的第一个例子，一个完全无机模拟的一部分FeMoco活性中心的固氮酶。我们详细的合成，表征和反应性的两个相关的，瞬态的含磷的无机簇，二氢化物配合物和乙烯基单氢化物配合物，其中承担的[Fe2MoOS3]部分FeMoco。二氢化物络合物能够经由乙烯基单氢化物络合物将乙炔还原成乙烯。在反应循环中，通过还原消除H2或乙烯从二氢化物或乙烯基单氢化物络合物中分别产生瞬态低价络合物。
We report the first example of a wholly inorganic mimic of a part of the FeMoco active centre of nitrogenases. We detail the synthesis, characterisation and reactivity of two related, transient hydride-containing inorganic clusters, a dihydride complex and a vinyl monohydride complex, which bear the [Fe2MoOS3] portion of FeMoco. The dihydride complex is capable of reducing acetylene to ethylene via the vinyl monohydride complex. In the reaction cycle, a transient low-valent complex was generated by the reductive elimination of H2 or ethylene from dihydride or vinyl monohydride complexes, respectively.
