The viability of these small-scale samples as starting materials for amide and cyclopentadienyl f-element complexes was tested by reacting KN(SiMe3)2, KCp′ (Cp′ = C5H4SiMe3), KCp′′ (Cp′′ = C5H3(SiMe3)2-1,3), and KC5Me4H with 1-Ln generated in situ. These reactions produced Ln[N(SiMe3)2]3 (4-Ln), Cp′3Ln (5-Ln), Cp″3Ln (6-Ln), and (C5Me4H)3Ln (7-Ln), respectively. Small-scale

The isomorphous and isostructural neutral molecules, M = La and Ce, are polymeric in the solid-state, as are those of M = Sm and Eu, which were reported in earlier work. The polymeric network is built from eight coordinate units whose geometry

    [Cp′′2Ln(E5)FeCp*] (Ln=La, Ce, Nd; E=P, As) were obtained. Their reactivity was studied by activation of P4, resulting in a selective expansion of the P5 rings. The obtained compounds [K(18-crown-6)] [Cp′′2Ln(P7)FeCp*] (Ln=La, Nd) are the first examples of an activation of P4 by a f-element-polypnictide complex. Additionally, the first systematic femtosecond (fs)-spectroscopy investigations of d/f-polypnictides
    迄今为止,由二价系元素引起的还原化学主要集中在sa上。考虑到系元素的丰富的物理性质,对一种元素的这种限制是一个缺点。由于几乎所有系元素的分子二价化合物都已经存在了一段时间,因此我们使用了一种已知的早期系元素和两种新的非经典还原剂来建立复杂的还原化学。其结果是,六个新的d / F-polyphosphides或d / F-polyarsenides,[K(18-冠-6)] [CP'' 2 LN(E 5)FeCP *](Ln为;得到E = P,As)。通过活化P 4来研究它们的反应性,从而导致P 5环的选择性膨胀。将所得到的化合物[K(18-冠-6)] [CP'' 2Ln(P 7)FeCP *](Ln = La,Nd)是通过f元素-多肽复合物激活P 4的第一个例子。此外,首次对d / f-多聚肽进行系统的飞秒(fs)光谱学研究是为了展示获得更广泛的系元素化合物所具有的优势。
