摘　　要：本论文介绍了一种更加合理的合成方式,用来合成基于N,N’-(双三甲基硅烷基)苯脒支撑无配位溶剂二价铁有机配合物。首先通过将常见配体的刚性基团替换成为了更加柔性的三甲基硅烷基,进一步提高了对应的钾盐的溶解度。因此在合成铁的配合物的过程中,可以使用无配位原子的甲苯作为溶剂进行合成。与此同时,考虑到二价铁盐往往伴随着三价杂质,因此直接采用其三价铁盐与还原剂石墨钾和其他原料一锅煮的方法,进行合成,在提高了产品纯度的同时,还进一步降低合成难度,简化了合成步骤,因此该文报道了一种高效优化的合成方式。by the adoption of N,N'-bis(trimethylsilyl)benzimidamide ligand,a divalent iron coordination compound was synthesized and characterized in which there is no coordination solvent molecules connecting to iron center.For the sake of a better solubility,the commonly used rigid substituent was replaced by a flexible and soft Me3Si-group and this resulted to an identically increase in the solubility of potassium salt and the iron coordination compound supported by this ligand.In addition,taking the trivalent impurities of divalent iron inorganic salt reactants due to the oxidation in the air,the synthesis we reported here in this contribution utilized trivalent iron slat with reductant potassium graphite and the rest starting materials by one-pot reaction method.Thus,the target produced was successfully achieved.It is worth mention,the synthetic access reported in this work not only optimized the synthesis to give better purity,but also simplified the reaction procedure.Thus,the synthetic strategy reported is of considerable efficiency.
