    Synthesis and thermal analysis of crosslinked imidazolium-containing polyester networks prepared by Michael addition polymerization
    摘要:
    Several new covalently crosslinked imidazolium-containing polyester networks were prepared by Michael addition polymerization to probe how ionic functionality might affect thermal properties such as glass transition temperature (T-g) and thermal decomposition (T-d5%). A structure-activity relationship was investigated involving a variation of the methylene spacer and the counteranion of the acetoacetate precursors. Analysis of T-g by differential scanning calorimetry (DSC) indicated that a longer methylene spacer (n = 6 versus 2) resulted in lower T-g values due to increased chain mobility. It was also discovered that the larger the counteranion, the lower the T-g(Br- > NO3- approximate to BF4- CF3CO2- > NTf2-). Thermogravimetric analysis (TGA) indicated that the thermal stability of the polyesters was inversely related to the basicity of the counteranion used, following the trend: (NTf2- > BF4- > NO3- > Br-). The exception was the trifluoroacetate-containing polyester, which exhibited the lowest thermal stability. Published by Elsevier Ltd.

  • Functionalized imidazoline-2-ylidene complexes of rhodium and palladium

    N-Heterocyclic ‘carbene’ ligands derived from imidazole are alternatives for the well-established phosphine ligands in organometallic catalysis. In contrast to phosphines, the carbene ligands do not undergo ready dissociation from palladium and rhodium so that immobilization techniques appear reasonable. The synthesis of novel, functionalized imidazoline-2-ylidene complexes suitable for reactions with
    衍生自咪唑的N-杂环“卡宾”配体是有机属催化中成熟的膦配体的替代物。与膦相反,卡宾配体不易于与解离,因此固定化技术显得合理。报道了适用于与官能化聚合物反应的新颖的,官能化的咪唑啉-2-亚烷基络合物的合成,以及溶性属络合物的合成。此外,提出了用于聚醚取代的咪唑啉-2-亚烷基络合物的模型化合物。
