The heterobimetallic CpFe(μ-η5: η5-as-indacenediide)RhL2 complexes (L2 = COD (2), NBD (3), (ethylene)2 (4)) have been obtained from metalation of the mononuclear lithium CpFe(η5-as-indacenediide) with [Rh(μ-Cl)L2]2. Mixtures of syn and anti heterobimetallic complexes were formed and fully characterized by 2D NMR spectroscopy. The reactivity at the rhodium center is greatly influenced by the presence
The monometallic complexes with Rh(COD) and Ir(COD) of 1,5- and 1,7-dihydro-s-indacene, 2,6-dimethyl-1,5-dihydro-s-indacene and 2,7-dimethyl-1,6-dihydro-as-indacene have been synthesized and characterized spectroscopically and structurally. Deprotonation and further complexation of these compounds afforded mixtures of syn and anti homobimetallic isomers. The syn/anti ratio depends on the structure of the ion pairs of the salt and on the s or as geometry of the bridging ligand. (C) 2000 Elsevier Science S.A. All rights reserved.
