Catalytic oligomerization of ethylene performed with the sterically hindered β-diimine ligand 2-(2,6-diisopropylphenyl)-amine-4-(2,6-diisopropylphenyl)-imine-2-pentene covalently ancored on SBA-15 mesoporous support employing the alkosilane 3-chloropropyltrimetoxysilane (CPTMS) for the first time. This material was tested as catalytic precursors for ethylene oligomerization processes and was characterized using various techniques such as small-angle XRD, elemental analysis, 1H and 29Si NMR, N2 sorption, gas chromatograph and flame atomic absorption spectroscopy. The heterogenized complex demonstrated an increase in selectivity for the products of interest (α-C4).

一种用于催化乙烯低聚的新型多相Ni/β-二亚胺/SBA-15配合物
使用位阻 β-二亚胺配体 2-(2,6-二异丙基苯基)-胺-4-(2,6-二异丙基苯基)-亚胺-2-戊烯共价固定在 SBA-15 介孔载体上的乙烯催化低聚反应3-氯丙基三甲氧基硅烷 (CPTMS) 首次出现。该材料作为乙烯低聚过程的催化前体进行了测试，并使用各种技术进行了表征，例如小角度 XRD、元素分析、1 H 和29 Si NMR、N 2吸附、气相色谱和火焰原子吸收光谱。异质化复合物显示出对目标产物 (α-C4) 的选择性增加。
