Synthesis of (peroxo)diiron(III) complexes having various core structures

合成了具有不同核心结构的(过氧基)Fe(III)2络合物，并研究了它们对外部底物的氧化反应活性。含三苯乙酸桥联的(过氧基)Fe(III)2络合物能够氧化BDEs为74-92kcal/mol的脂肪族C-H键。还制备了一个带有三脚架配体的单核过乙酰化铁(III)配合物。该络合物是结构和光谱上定义良好的非血红素型过乙酰铁(III)络合物的第一个例子，对三苯基膦、一些烯烃和金刚烷的第三C-H键具有适度的氧化能力。

(peroxo)Fe(III)2 complexes having various core structures were prepared and their oxidation reactivity towards external substrates were investigated. (peroxo)Fe(III)2 complex with a triphenylacetate bridge is capable of the oxidation of aliphatic C-H bonds having BDEs from 74-92 kcal/mol. A mononuclear peracetatoiron(III) complex with a tripodal ligand was also prepared. This comples is the first example of a structurally and spectroscopically well-defined non-heme type peracetatoiron(III) complex and has modest oxidation ability toward triphenyl phosphine, some olefins, and the tertiary C-H bond of adamantane.
