  Preparation and ESR characterization of polyalkyl-s-indacenyl anion-radicals from polyalkyl-1,5-dilithio-s-indacenes

  摘要：

  Polyalkyl-(or chloropolyalkyl)-s-indacenyl anion radicals were obtained from the organodilithium derivatives of the corresponding substituted-1,5-dihydro-s-indacenes by three different methods: (i) UV photolysis, (ii) oxidation by a ferrocenium salt, (iii) single electron transfer reaction from an electron rich olefin. The last reaction (iii) involves transient formation of an unstable polyalkyl-lithio-s-indacenyl imidazolidinium salt. The same salt, obtained by another way by reacting 1,3-dimethylimidazolidinium chloride with the polyalkyl-1,5-dilithio-s-indacene, also leads to the corresponding lithium polyalkyl-s-indacenyl anion radical. All lithium polyalkyl-s-indacenyl anion radicals studied were characterized from their ESR spectra. They present a characteristic symmetrical spin distribution. On the contrary a Rhodium-COD polyalkyl-s-indacene radical presents a non symmetrical spin distribution. (C) 2010 Elsevier B.V. All rights reserved.

  A new fused ring compound, 2,6-dibutyl-4,8-dimethyl-1,5-dihydro-s-indacene (VII) (H₂L), has been synthesized from 2,5-dimethyl-1,4-dibromomethylbenzene in almost quantitative yield. Two organomtallic binuclear complexes, [Cp*Fe-L-FeCp*] (1) and the mixed-valence compound [Cp*Fe-L-FeCp*]⁺ BF^–₄ (2), have been characterized by spectroscopic and electrochemical techniques. The cyclic voltammogram of 1 exhibits a potential difference of 668 mV between two redox peaks and the UV-vis-NIR spectra of compound 2 shows an intervalance charge transfer band at 1794 nm. The information gathered by these techniques indicates that the studied binuclear complex has strong interaction between the two metal centres.
