  摘要：

  The exchange reaction between transition metal(II) acetates and the protic nucleophiles 3-(1-aminoethylidene) pentane-2,4-dione (Hampd) or 3-acetylpentane-2,4-dione (Hacpd) affords the corresponding [M(ampd)(2)] (M = Ni (1), Pd (2)) or [M(acpd)(2)] (M = Mn (5), Fe (6), Ni (7), Cu (8), Pd (9)) complexes in fair to good yields. The reaction is performed in ethanol at room temperature, with addition of sodium carbonate in some cases. This last new synthetic procedure is applied for those complexes which easily undergo an extensive deacylation process. The factors determining the success of the exchange reaction and the resulting N, O or O, O coordination are fully discussed. (C) 2008 Elsevier B.V. All rights reserved.

• Reaction of the framework 3d-organometallosiloxanes with acetylacetone

  A reaction of acetylacetone with the framework sandwich-type metallosiloxanes (MOS) of general formula [PhSiO2]6M6[PhSiO2]6, where M = Cu, Ni, Mn, was studied by GPC, 1H and 29Si NMR spectroscopy, X-ray diffraction, elemental and functional analysis. The reaction involved replacement of the metal atoms with the hydrogen atoms and is accompanied by the formation of the corresponding chelate complexes M(acac)2. Displacement of the metal from the framework MOS leads to the destruction of molecular skeleton and formation of phenylsiloxanes containing Si-OH groups. The yield and composition of the reaction products considerably depend on the nature of the metal in [PhSiO2]6M6[ThSiO2]6. A selective substitution of the metal leads to the stereoregular hexahydroxyhexaphenylcyclohexasiloxane, [PhSiO(PH)]6, cis-isomer. The structure and composition of the crystalline hexahydroxyhexaphenylcyclohexasiloxane obtained were confirmed by 29Si NMR spectroscopy, X-ray diffraction study, and functional analysis, while its TMS derivative was studied with 1H NMR spectroscopy and GPC. Using a framework manganese phenylsiloxane as an example, a reversible character of the process has been established and an alternative synthesis of this compound from hexahydroxyhexaphenylcyclohexasiloxane and Mn(acac)2 has been accomplished for the first time.

  对通式为[PhSiO2]6M6（其中M = Cu, Ni, Mn）的框架夹心型金属硅氧烷（MOS）与乙酰乙酮的反应进行了研究，使用了GPC、1H和29Si NMR光谱、X射线衍射、元素分析和功能分析。反应过程涉及金属原子被氢原子取代，并伴随形成相应的配位化合物M(acac)2。从框架MOS中取代金属会导致分子骨架的破坏，并形成含有Si-OH基团的苯基硅氧烷。反应产物的产率和组成显著依赖于[PhSiO2]6M6中金属的性质。金属的选择性取代导致了立体规律性的六羟基六苯基环己硅氧烷[PhSiO(PH)]6的顺异构体的形成。所获得的结晶六羟基六苯基环己硅氧烷的结构和组成通过29Si NMR光谱、X射线衍射研究及功能分析得到了确认，而其TMS衍生物则通过1H NMR光谱和GPC进行了研究。以框架锰苯基硅氧烷为例，确立了该过程的可逆特征，并首次完成了从六羟基六苯基环己硅氧烷和Mn(acac)2合成该化合物的替代合成。

• Synthesis and Characterization of Some New Manganese(II) Complexes, Manganese(III) Heterochelates, and µ‐Dioxo‐dimanganese(IV) Complexes Involving Tetradentate Schiff Bases

  Condensation of 1,3-diaminopropane-2-ol with diacetylmonoxime and acetylacetone yielded the tetradentate Schiff bases N,N'-(2-hydroxy) propylene-bis(2-imino-3-oximino)butane} (H2L2) and N,N'-(2-hydroxy) propylene-bis(acetylacetoneimine) (H2L2), respectively. The ligands form mononuclear manganese(II) complexes of the type [Mn(II)(L-1)] (1) and [Mn(II)(L-2)] (3), which are used for the formation of the manganese(III) heterochelates of the type [Mn(III)(L)(L-L)] (where H2L = H2L1 or H2L2; L-L = anion of acetylacetone or salicylaldehyde). Cationic heterochelates of the type [Mn(L)(L-L)]ClO4 where H2L = H2L1 or H2L2 and L-L = ethylenediamine and N,N'-propylene-bis(benzaldimine) (L-3) have been synthesized by the reactions of bis(acetylacetonato)manganese(II) or bis(salicylaldehydato)manganese(H) with the preformed Schiff bases or by the reactions of [Mn(II)(L-1)] or [Mn(II)(L-2)] with L-L in absolute alcohol under reflux. Some of the complexes, synthesized here, may be used as precursors in the synthesis of higher nuclearity manganese complexes. Air oxidation of [Mn(II)(L-1)] (1) and [Mn(II)(L-2)] (3) in DMF yielded the dark-brown mu-dioxo-bis-[N,N'-(2-hydroxy)propylene-bis(2-imino-3-oximino)butane}]dimangenese(IV) (2) and mu-dioxo-bis[N,N'-(2-hydroxy)propylenebis(acetylacetoneimine)}]dimangenese(IV) (4) complexes, respectively. All of the complexes have been characterized with the help of elemental analyses, molar conductance values, molecular weights, magnetic moments, and spectroscopic (IR, UV-VIS, ESR) data.
