  摘要：

  phosphadicarbollide 阴离子 [7,8,9-PC2B8H10]– (4) 与 [CpFe(C6H6)]+ 或 [Cp*Fe(MeCN)3]+ 的反应得到预期的 12-vertex ferraphosphadicarbollides [1-C5R5-1 ,2,3,4-FePC2B8H10] [R = H (5a), Me (5b); 金属原子被指定为编号 1]，产率约为 35%。化合物 5a,b 在 150 °C 下进行选择性多面体重排，得到相应的异构体 [1-C5R5-1,2,4,5-FePC2B8H10] (6a,b)。5a 的结构已通过 X 射线衍射确定。电化学研究表明，获得的所有化合物都显示出 FeII/FeIII 氧化过程，并在循环伏安时间尺度上具有化学可逆性。然而，只有阳离子 [6b]+ 在电解的长时间尺度上是相当稳定的。Ferraphospadicarbollides

  AbstractThermal isomerisation of the ferraphosphadicarbaborane [1‐Cp‐closo‐1,2,4,5‐FePC2B8H10] (1a; Cp = η5‐C5H5−) at elevated temperatures (180−350 °C) leads to the formation of three new isomeric complexes. These were characterized by multinuclear (1H, 11B, 31P, and 13C) NMR spectroscopy and mass spectrometry as [1‐Cp‐closo‐1,2,3,8‐FePC2B8H10] (1b), [1‐Cp‐closo‐1,10,2,4‐FePC2B8H10] (1c), and closo‐[1,2,4,10‐FePC2B8H10] (1d). The formation of 1b is accompanied by an unusual agglomeration of the P and C heteroatoms. Complexes 1b and 1c have also been isolated as side products from the direct reaction between nido‐[7,8,9‐PC2B8H11] (2) and [CpFe(CO)2]2 in refluxing mesitylene, and 1a and 1b from the pyrolysis of [7‐Fp‐(η1‐nido‐7,9,10‐PC2B8H10)] [3; Fp = CpFe(CO)2] at 350 °C. NMR intercomparisons of all five [1‐Cp‐closo‐FePC2B8H10] isomers thus far isolated have been made. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
