Synthesis and characterization of the novel Al^I compound Al(C<inf>5</inf>Me<inf>4</inf>Ph): Comparison of the coordination chemistry of Al(C<inf>5</inf>Me<inf>5</inf>) and Al(C<inf>5</inf>Me<inf>4</inf>Ph) at d ¹⁰ metal centers

Abstract:

The synthesis of the novel AlI compound AlCp*Ph (Cp*Ph = C5Me4Ph) is presented. This compound is characterized by 1H, 13C, 27Al NMR spectroscopy, elemental analysis as well as its reactivity towards the α,ω-diolefin dvds (dvds = tetramethyl-divinyl-disiloxane). Also the reactivity of AlCp* towards dvds is investigated and the product [(dvds)(μ2-AlCp*)2] characterized by NMR spectroscopy, elemental analysis as well as X-ray crystallography. Furthermore, two new coordination compounds of AlCp* to d10 metal centers are synthesized and characterized. [Pd(AlCp*)4] is obtained by reaction of [(tmeda)PdCl2] with AlCp*, and [Ni(AlCp*) 4] is synthesized from [Ni(cod)2] and AlCp* via ligand substitution. Both complexes are spectroscopically and crystallographically characterized. Finally, preliminary results on the coordination of AlCp*Ph to Ni0 and Pd0 centers will be discussed. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
