  Tribochemically active chelate complexes of salicylideneimines

  摘要：

  N-Alkylsalicylideneimines and their complexes with 3d metals were obtained by chemical (from metal salts) and electrochemical methods (from metals in the zero oxidation state). The compounds obtained were characterized by IR and H-1 NMR spectroscopy and X-ray diffraction analysis. According to crystallographic data, nickel bis(chelate) exists in the trans-planar configuration. A friction test revealed that the tribotechnical characteristics of lubricating formulations are substantially enhanced in the presence of N-alkylsalicylideneiminates.

  Electronic spectrophotometry has been empolyed to study the mechanism of transimination in bis(N-alkylsalicylaldiminato)nickel(II) complexes (alkyl = Me, Et, Pri, Prn or Bun) by ammonium ion in acetonitrile. The reaction is clearly biphasic: fast addition of ammonium and slow elimination of alkylammonium ions. The addition reaction involving the two azomethine bonds of the complex occurs by two consecutive

  电子分光光度法已empolyed研究transimination的在双机制（Ñ -alkylsalicylaldiminato）镍（II）配合物（烷基=甲基，乙基，镨我，镨Ñ或卜ñ）通过铵离子的乙腈。该反应显然是两相的：快速添加铵和缓慢消除烷基铵离子。涉及两个配合物的两个偶氮甲碱键的加成反应通过两个连续的过程发生，并且对于R = Bu n，发现了一个二项速率定律。在连续消除反应中，仅观察到一个速率常数，该常数取决于p K a和所留下的烷基铵离子的空间应变。

• Tethering of nickel(II) Schiff-base complex onto mesoporous silica: An efficient heterogeneous catalyst for epoxidation of olefins

  A new hybrid catalyst has been prepared by tethering a nickel(II) Schiff-base complex via post-synthesis modification of mesoporous silica, MCM-41. The Schiff-base has been derived from salicylaldehyde and 3-aminopropyltriethoxysilane (3-APTES) which is chemically anchored on MCM-41 via silicon alkoxide route. The anchored Schiff-bases imposed a stable planar coordination geometry around the central nickel ions. The catalyst has been characterized by elemental analysis, FT-IR, UV-Vis, small angle X-ray diffraction (SAX) and transmission electron microscopy (TEM) studies. The SAX and TEM measurement showed the mesoporosity of the catalyst. The activity of the catalyst has been assessed in the epoxidation of olefins using tert-butyl-hydroperoxide (tert-BuOOH) as oxidant in heterogeneous condition. Immobilized nickel catalyst was found to be catalytically more active and selective compared to the similar type of nickel(II) complex as well as Ni(NO3)(2)center dot 6H(2)O in homogeneous media. The catalyst can be recycled and reused several times without significant loss of activity. (C) 2011 Elsevier Ltd. All rights reserved.
