  负载在超顺磁性Fe 3 O 4 @SiO 2纳米颗粒上的金属离子席夫碱配合物：一种无溶剂条件下由醛合成1,1-二乙酸酯的有效，选择性和可回收催化剂

  摘要：

  我们报告了一种新的多步法制备具有高饱和磁化强度的功能化超顺磁性Fe 3 O 4 @SiO 2。在第一步中，以纳米Fe 3 O 4为核，TEOS为二氧化硅源，PVA为表面活性剂，合成了Fe 3 O 4 @SiO 2纳米球核-壳。然后，由席夫碱与金属乙酸盐[Co（OAc）2，Mn（OAc）2，Ni（OAc）2，Cu（OAc）2，Hg（OAc）2，Cr （OAc）3和Cd（OAc）2在Fe 3 O 4 @SiO 2表面上。通过透射电子显微镜（TEM）和振动样品磁强计（VSM）仪器鉴定功能化磁性二氧化硅的结构和磁性。此外，功能化的Fe 3 O 4 @SiO 2具有超顺磁特性，饱和磁化强度约为34 emu / g。NMR，FT-IR，元素分析和XRD也用于鉴定这些结构。Fe 3 O 4 @SiO 2的催化能力发现金属离子的/席夫碱络合物是在室温下在温和且无溶剂的条件下将醛转化为其相应的1，1-二乙酸

  Unsubstituted and tertiary-butyl substituted salicylaldimine complexes of Cu(II) and Co(II) immobilized on silica supports (MCM-41, SBA-15 and Davisil 710) were tested as catalysts for cyclohexene oxidation using hydrogen peroxide as an oxidant under an oxygen atmosphere. The effect of the nature of the salicylaldimine ligand and the type of support were investigated. Allylic species were isolated

Template method has been used to prepare compounds that have remarkable topologies, such as helicates, rotaxanes and catenanes [8]. Schiff base complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) have been prepared

  在模板方法中，金属离子可以在将反应导向所需的配体产物或帮助其分离方面发挥重要作用。模板法的例子是乙二胺和 2,5-二羟基苯乙酮在乙酸双氧铀溶液存在下的反应 [1-6]。当胺或醛发生变化时，可以获得各种席夫碱。因此，可以轻松合成大量具有不同结构特征的希夫碱。它们可以有额外的供体原子，如磷、氧、硫等，这使它们成为金属离子络合和模拟生物系统的良好供体原子。它们可以通过在脂肪族或芳香族链中插入适当的基团来官能化 [7]。模板法已被用于制备具有显着拓扑结构的化合物，如螺旋、轮烷和链烷 [8]。Mn(II)、Fe(III)、Co(II)、Ni(II)、Cu(II) 和 Zn(II) 的席夫碱配合物已通过模板法使用 L-组氨酸、喹喔啉-2-羧基醛和金属离子[9]。以及用于制备配合物的模板法通过 3-氨基丙基三乙氧基硅烷和水杨醛合成 Sn(II)、Sn(IV) 和 Co(II) 配合物并评估它们的抗菌敏感性

  Heterogeneous catalysts were prepared by covalent bonding of transition-metal salicylaldimine complex to alpha-zirconium phosphate, abbreviated as alpha-ZrP.M(salicylaldimine) where M = Co, Mn and Cu}. The resulting compounds were characterized by BET surface area, TGA analysis, X-ray diffraction, Scanning electron micrograph, energy dispersive X-ray analysis, Fourier transform infrared and Atomic absorption spectroscopy. The catalytic activity of alpha-ZrP.M(salicylaldimine) was studied for the liquid phase oxidation of cyclohexane using terr-butylhydroperoxide as an oxidant under solvent free condition. In the oxidation reaction, cyclohexane was oxidized to cyclohexanol, cyclohexanone and some unidentified products. It was found that the reactivity of alpha-ZrP.M(salicylaldimine) catalyst for the oxidation reaction decreased in the order alpha-ZrP.Co(salicylaldimine) > alpha-ZrP.Mn(salicylaldimine) > alpha-ZrP.Cu(salicylaldimine). A maximum conversion of cyclohexane (14.18%) and selectivity of cyclohexanol (4.99%), cyclohexanone (87.34%) and some other products (7.67%) was observed for catalyst, alpha-ZrP.Co(salicylaldimine) after 6 h at 353 K. The catalyst, alpha-ZrP.Co(salicylaldimine) was reused for four cycles without significant loss of catalytic activity. (C) 2015 Elsevier B.V. All rights reserved.

  Covalently anchored transition-metal salicylaldimine complexes on alpha-titanium phosphate alpha-TiP.M(salicylaldimine) where M = Co, Cr, Cu and Fe} were synthesized by in situ method and characterized by BET surface area, XRD, SEM, EDX, FTIR, TGA and ICP techniques. Its catalytic activity was tested for the oxidation of cyclohexane under solvent free condition using tert-butyl hydroperoxide as an oxidant. The oxidation of cyclohexane gave cyclohexanol, cyclohexanone and some unidentified products. The activity of heterogeneous catalysts in the oxidation reaction decreased in the order of alpha-TiP.Co(salicylaldimine) > alpha-TiP.Cr(salicylaldimine) > alpha-TiP.Cu(salicylaldimine) > alpha-TiP.Fe(salicylaldimine). The alpha-TiP.Co(salicylaldimine) gave maximum conversion 14.85 % of cyclohexane with 92.13 % selectivity of KA-oil (cyclohexanol + cyclohexanone) in 6 h. The catalyst, alpha-TiP.Co(salicylaldimine) was reused for five cycles without significant loss of catalytic activity.A heterogeneous catalytic system, alpha-TiP.Co(salicylaldimine)/TBHP gave maximum 14.85 % conversion and 92.13 % selectivity for KA-oil in oxidation of cyclohexane. The catalyst can be reused for five cycles.[GRAPHICS]
