  摘要：

  制备并表征了带有悬垂羧基的Ni II和Mn III Schiff碱配合物（Salophen-Ni和Salophen-MnCl）。通过在支持物的丙胺基团和Salophen配体的羧酸官能团之间形成酰胺官能团（分别对应于Ni的1.30 wt。％和1.06 wt％的相对应），将两种复合物都嫁接到介孔的氨基官能化SBA-15二氧化硅上。 ％的Mn）。然后，使用四丁基溴化铵（n- Bu 4 NBr）作为主要催化剂，在CO 2环加成反应中对游离和接枝配合物的共催化行为进行了评估。在均相条件下，Mn III Schiff碱配合物和NiII在较小程度上充当了该反应的有效助催化剂（在120°C，15 bar CO 2下3 h后，苯乙烯转化率分别为100％和65％）。当固定在氨基官能化SBA-15的表面上时，我们发现效率较低的SBA-15的共催化活性。e。Ni 2+ salophen配合物可以增强（7小时后达到

  New ways of the covalent immobilization of Mn(III) and Mo(IV) Salen complexes on a mesoporous silica support to produce a stable heterogeneous catalyst for epoxidation reactions are reported. Peptide and ester interactions were employed to anchor the metal Salen complex on the organo-modified silica framework. Electrospray MS, FTIR, TGA, ICP-OES and elemental analysis were used for quantitative and qualitative analyses of the immobilized Salen complexes. The results confirm the location of the metal Salen complex inside the mesopores covalently attached to the silica framework. (c) 2006 Elsevier B.V. All rights reserved.

  The covalent immobilization of Mn(III)-Salen complexes on an amorphous mesoporous silica support is reported. Both (3-aminopropyl)trimethoxysilane (APTMS) and (3-iodopropyl)trimethoxysilane (IPTMS) were used in a post-synthesis grafting method to prepare organosilane-modified porous materials. Peptide and ester interactions were employed to anchor the Salen complex to the silica framework. The catalytic activity of the immobilized Salen catalyst was studied by epoxidation of cyclooctene. The comparison of the homogeneous and the immobilized catalyst shows that there was no significant loss of catalytic activity for epoxidation by immobilization. In the current study, the effects of reaction temperatures, solvents, and amount of catalyst on the catalytic activity were investigated. The optimal yield of cyclooctene oxide was obtained at 45 degrees C using toluene as the solvent.
