    摘要:
    在乙烯或 COD 存在下,二茂铁与锂的反应允许大规模制备 Fe(0)-ate 络合物 1 和 4,结果证明它们是各种 Alder-ene 的优良催化剂,[4 +2]、[5+2] 和 [2+2+2] 环加成和多不饱和底物的环异构化反应。固态高铁酸盐 1 和 4 的结构揭示了还原铁中心与配体球共享电子密度的能力。这一特征与结合烯烃的动力学不稳定性相结合,被认为是不同烯炔或二炔底物易于氧化环化作为观察到的骨架重组的触发事件的原因。这种机械建议得到了高度指示性的氘标记实验的证实。而且,借助 Fe(+1) 配合物 6,可以拦截氧化环化歧管的两种不同产物,尽管其电子数为 17,但在某些情况下也具有催化能力。来自 6 和 tolane 的不寻常的环丁二烯配合物 38 用 X 射线晶体学表征。

    The scope and the mechanism of the reactions of [CpFe(COD)][Li(TMEDA) (Cp = C5H5-; COD = 1,5-cyclooctadiene; TMEDA = Me(2)NCH(2)CH(2)NMe(2)), 1, with a number of organic monohalides and geminal dihalides were investigated. With monohalides organic coupling products were observed, and, in:particular, the coupling and cross-coupling of benzyl and allyl halides were studied in detail. The addition of 1 equiv of benzyl halide to 1 in benzene resulted in the initial formation of [CpFe(COD)(CH(2)Ph)], 7. The predominant pathway involved an initial one-electron transfer from [CpFe(COD)](-) to PhCH(2)X to form PhCH(2)X*(-) and [CpFe(COD)]*. PhCH(2)X*(-) quickly disproportionated to form PhCH(2)* and X(-). The benzyl radical then added to [CpFe(COD)]*. Once formed [CpFe(COD)(CH(2)Ph)] reacted with TMEDA in a disproportionation reaction to form 0.5 equiv of the paramagnetic compound, [(TMEDA)Fe(CH(2)Ph)(2)], 3, and 0.5 equiv of FeCp(2). When additional benzyl (or allyl) halide was added, it reacted with [(TMEDA)Fe(CH(2)Ph)(2)] to form the coupled (or cross-coupled) product. This coupling reaction involved the intermediacy of benzyl (and allyl) radicals, and the experimental results were consistent with the product being formed by the coupling of two radicals in solution.
