Abstract

Herein, we report the preparation and characterization of two diiron carbonyl complexes with ethyldiphenylphosphine or dicyclohexylphenylphosphine. Me₃NO-driven decarbonylation of complex [Fe₂(CO)₆(µ-SCH₂CH₂CH₂S)] (1) with the corresponding phosphine ligands afforded the products [Fe₂(CO)₅(Ph₂PCH₂CH₃)(µ-SCH₂CH₂CH₂S)] (2) and [Fe₂(CO)₅PhP(C₆H₁₁)₂(µ-SCH₂CH₂CH₂S)] (3) in 91% and 84% yields, respectively. The structures of complexes 2 and 3 have been identified by spectroscopy, elemental analysis, and X-ray diffraction analysis. Moreover, the electrochemistry was investigated by cyclic voltammetry.

摘要

在本文中，我们报道了两种二铁羰基铁与乙基二苯基膦或二环己基苯基膦的制备和表征。由Me ₃ NO驱动的配合物[Fe ₂（CO）₆（µ -SCH ₂ CH ₂ CH ₂ S）]（1）与相应的膦配体进行脱羰，得到产物[Fe ₂（CO）₅（Ph ₂ PCH ₂ CH ₃）（µ -SCH ₂ CH ₂ CH ₂ S）]（2）和[Fe ₂（CO）₅PhP（C ₆ H ₁₁）₂（µ -SCH ₂ CH ₂ CH ₂ S）]（3）的产率分别为91％和84％。配合物2和3的结构已通过光谱，元素分析和X射线衍射分析确定。此外，通过循环伏安法研究了电化学。
