摘要：
The reactions of the Fe(II) and Ru(II) halogenide complexes [Fe(PPh3)(2)Br-2] [Fe(NCCH3)(2)Br-2], [Ru(PPh3)(3)Cl-2], and [Ru(dMSO)(4)Cl-2] with GaCp* and AlCp*, respectively, are investigated. The reactions of [FeBr2L2] with ECp* exclusively proceed via Cp* transfer, leading to [FeCp*(GaCp*)(GaBr2)(PPh3)] (1) (L = PPh3, E = Ga), [FeCp*(GaCp*)(2) (GaBr2)] (2) (L = NCCH3, E = Ga) and [FeCp*(mu(3)-H)(kappa(2)-(C6H4)PPh2)(AlCp*)(AlBr2)](3) (L = PPh3, E = Al), the latter of which is formed via orthometallation of one PPh3 ligand. The reaction of [Ru(dmso)(4)Cl-2] leads to the homoleptic complex [Ru(GaCp*)(6)Cl-2](4) in high yields, while [Ru(PPh3)(3)Cl-2] gives 4 in rather low yields. The reason for this difference in reactivity is investigated and it is shown that Cp* transfer and orthometallation are the limiting side reactions of the reaction of [Ru(PPh3)(3)Cl-2] With GaCp*. All compounds were characterized by NMR spectroscopy, and single crystal X-ray diffraction studies were performed for 1, 3, and 4. (c) 2006 Elsevier B.V. All rights reserved.
