| Iron sulfur cluster compounds widely exist in nature, they are act as an active center units in biology enzyme materials. Because of the mild and efficient catalytic ability of the enzyme, the structure and function of its core structure units-cluster compounds have received much attention.Our group devotes to studying on the dinuclear iron sulfur clusters of nitrogenase model. By modifying the structure of sulfur ligands we found different sulfur ligands on iron have a great influence on the properties of clusters.1,8-naphthalene imide compounds have good fluorescence function and good electron transfer induction function, at the same time this kind of compound structure is easy to modi-fy Herein, we described the synthesis, structure and performance of several novel iron sulfur clusters containing4,5-dithiolato-1,8-naphthalene imide ligand, including:(1) Using acenaphthene as raw material, the ligand1,N-butyl-4,5-disulfide naphthalene imide, was synthesized via chlorination, oxidation, amination and sulfuration;(2) Three novel diiron sulfur clusters containing4,5-dithiolato-1,8-naphthalene imide ligand,[Cp*Fe(μ-4,5-S2-R)(μ-CO)FeCp*](3a),[Cp’Fe(μ-4,5-S2-R)(μ-CO)FeCp’](3b),[Cp2Fe2(C,6N1O2S1)2](4)(Cp*=η5-C5Me5,3a; Cp’=η5-C5Me4,3b; Cp=η5-C5H5,4; R=N-buty1-1,8-naphthalene imide) were synthesized v/ia the reaction of N-butyl-4,5-disulfide-1,8-naphthalene imide and [Fe(CO)2Cpt]2;(3)3a was oxidized by HBF4to form3a[BF4];(4)3a[BF4] reacted with NO to generate a novel NO bridged diiron sulfur cluster [Cp*Fe(μ2-4,5-S2-R)(μ-NO)FeCp*][BF4](5);(5)3a[BF4] reacted with TEBAC to give a novel three terminal CO coordinated diiron sulfur cluster [Cp*Fe(CO)2(μ2-4,5-S2-R)(CO) FeCp*];All these new complexes were structurally characterized by X-ray analysis. |
