Abstract

[{Cp'Fe(μ-I)}₂] (I; Cp' = η⁵-1,2,4-(Me₃C)₃C₅H₂) reacts with [Na(OCP)(1,4-dioxane)_x] and K(OCAs) to yield [(Cp'Fe)₂(μ-η²:η²-P₂)(μ-CO)] (1) and [(Cp'Fe)₂(μ-η²:η²-As₂)(μ-CO)] (3), respectively. While complex 1 was previously accessed by Scherer and co-workers using rather harsh reaction conditions, the new synthetic method already proceeds at ambient temperature. UV-light irradiation of 1 and 3 induces CO release forming complexes [(Cp'Fe)₂(μ-η²:η²-E₂)] (E = P (2) and As (4)), respectively. However, both reactions also yielded several byproducts which were spectroscopically identified. Furthermore, upon thermally triggered CO elimination from 3 the Fe₃As₆-cluster [(Cp'Fe)₃(As₃)₂] (5) is isolated in low yield. In addition, zero-field ⁵⁷Fe Mössbauer spectra were recorded on complexes 1-4 and computational studies complement the experimental findings and provide additional insights into the bonding in these complexes and the reaction pathways resulting in the formation of complexes 1-4.

[{Cp'Fe(μ-I)}2]对3-磷酸和3-氨基乙酯的反应性。

[{Cp 'Fe(μ- I)} 2](我;Cp =η5 - 1,2,4 - (Me3C) 3 c5h2)反应(Na ((OCP)(1,4 -二恶烷)x)和K(亚奥理事会)收益率[(Cp 'Fe) 2(μ-η2:η2 p2)(μco)](1)和((Cp 'Fe) 2(μ-η2:η2-As2)(μ有限公司))(3),分别。先前，Scherer和他的同事在相当苛刻的反应条件下获得了1号复合物，而新的合成方法已经在室温下进行了。紫外光照射1和3诱导CO释放形成配合物[(Cp'Fe)2(μ-η2:η2-E2)] (E = P（2)和As(4)）。然而，这两种反应也产生了几种经光谱鉴定的副产物。此外，通过热触发CO从3中消除，fe3as6簇[(Cp'Fe)3(As3)2](5)在低产率下被分离出来。此外，在配合物1-4上记录了零场57Fe Mössbauer光谱，计算研究补充了实验结果，并提供了这些配合物中的键合以及导致配合物1-4形成的反应途径的额外见解。

期刊介绍： Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields. Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world. All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times. The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems. Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
