Synthesis and structure of a novel Pd(0)–Pd(IV)–Pd(IV)–Pd(0) mixed-valence complex
摘要:
The interaction of PdCl2(PhCN)(2) with 1,2-[PhP(H)CH2CH2CH2P(Ph)CH2](2)C6H4, generated in situ from the reduction of the corresponding phosphine oxide with LiAlH4 in the presence of Me3SiCl, gave a complex mixture, from which a di- and a tetranuclear palladium complex I and 2 whose solid state structures were ascertained by X-ray crystallography, were isolated. A novel Pd(0)-Pd(IV)-Pd(IV)-Pd(0) mixed-valence structure was observed in complex 2. (C) 2004 Elsevier B.V. All rights reserved.
