  具有尿素或氨基甲酸酯部分的新型磁性纳米粒子的合成：在Strecker合成α-氨基腈中的催化剂应用

  摘要：

  报道了四种具有脲或氨基甲酸酯部分的新型磁性纳米颗粒催化剂。通过添加3-（三乙氧基甲硅烷基）丙基异氰酸酯（TESPIC），胺或氨基醇，可以简单地对二氧化硅涂覆的磁性纳米颗粒进行功能化。具有双不稳定官能团的TESPIC被用作合成氨基甲酸酯基催化剂的合适前体。使用多种技术对新合成的催化剂进行了全面表征。这些功能化的磁性纳米颗粒在无溶剂条件下于50°C的Strecker合成α-氨基腈衍生物中用作可重复使用的催化剂。

  Surface modification of the luminescent silica nanoparticles doped with Tb(III)-p-sulfonatothiacalix[4]arene complex was carried out using a series of nitrogen/oxygen-containing trialkoxysilanes. It was found that groups capable of nonspecific interactions on the surface of the nanoparticles cause a significant decrease in their colloidal stability. The chromophore moieties in the modifiers were found to quench the luminescence of the nanoparticles. The surface modification of the nanoparticles is responsible for the change in the mechanism of luminescence quenching in the presence of copper(II) ions due to decreased accessibility of luminophores to the quencher.

  Four novel magnetic nanoparticle catalysts with urea or urethane moieties are reported. The silica‐coated magnetic nanoparticles were simply functionalized via addition of 3‐(triethoxysilyl)propylisocyanate (TESPIC), amine or amino alcohol. TESPIC with dual labile functional groups was used as a suitable precursor for the synthesis of urethane‐based catalysts. The newly synthesized catalysts were fully
