  The synthesis of the bis(eta(5)-indenyl)iron sandwich complexes (eta(5)-1-SiMe3-C9H6)(2)Fe (3a), (eta(5)-2-SiMe3-C9H6)(2)Fe (3b), [eta(5)-1,2-(SiMe3)(2)C9H5](2)Fe (4a) and [eta(5)-1,3-(SiMe3)(2)C9H5](2)Fe (4b), by the reaction of the appropriate lithium indenide salts [prepared from 1-SiMe3-C9H7 (2a), 2-SiMe3-C9H7 (2b), 1,2-(SiMe3)(2)C9H6 (2c) or 1,3-(SiMe3)(2)C9H6 (2d)] with ferrous chloride (1) in a 2:1 molar ratio is discussed. The solid-state structure of 4b was determined by single-crystal X-ray diffractometry. Complex 4b exists in a gauche conformation, showing that the indenyl ligands are sterically imposed by the bulk of the Me3Si substituents. The average Fe-C distance is 2.091(3) Angstrom. Cyclovoltammetric studies indicate that 3 and 4 are redox-active with one-electron oxidations [E-1/2 = -270 to -360 mV versus Fc/Fc(+), Fc = (eta(5)-C5H5)(2)Fe]. (C) 2003 Elsevier B.V.

• Trimethylsilyl-Substituted Indenyl-TiCl₃ Half-Sandwich Complexes:  Synthesis, Solid-State Structure, and Analysis of Substituent Effects
  作者：Thomas Weiss、Uwe Böhme、Bernhard Walfort、Gerd Rheinwald、Heinrich Lang

  The regioselective synthesis of (eta(5):2-Me3SiC9H6)TiCl3 (4) was effected by the reaction of TiCl4 with 1,2-(Me3Si)(2)C9H6 (3). The solid-state structure of 4 is reported and compared with those of (eta(5):1-Me3SiC9H6)TiCl3 (6) and (eta(5):C9H7)TiCl3 (5). To investigate the position-dependent effect of the Me3Si group, UV-vis spectroscopic and cyclic voltammetric studies were carried out. The results obtained give an insight into the relative energy levels of the frontier molecular orbitals of the respective indenyl titanium trichlorides. Quantum-chemical modeling studies were carried out on 4-6 to demonstrate the influence of the Me3Si substituent effect with respect to the structural changes in the indenyl ligand and the Ti-D interaction (D = centroid of the five-membered ring of the indenyl moiety).
