设计并合成了双功能多相催化剂，表示为DMEDA/IL-NH 2-MIL-101。采用SEM、N2吸附-脱附、XPS、FT-IR、PXRD、元素分析和TGA技术对DMEDA/IL-NH 2-MIL-101及其前体的结构和物理化学表征进行了表征。结果表明，N，N-二甲基乙二胺（DMEDA）和溴化1-丁基-3-甲基咪唑（BmimBr）两种催化组分被化学固定在NH 2-MIL-101纳米笼中。以N-Cr配位共价键将DMEDA胺接枝到NH 2-MIL-101载体上，通过“瓶中船”法将离子液体BmimBr（IL（Br−））锚定在NH 2-MIL-101纳米笼中，其中NH 2-MIL-101的胺基先与N，N-羰基二咪唑（CDI）缩合，再与1-溴丁烷烷基化。这种具有两个不同活性中心的新型多相催化剂可以在温和的无溶剂条件下有效地催化由二氧化碳（CO2）、环氧化物和苯胺一锅法合成N-芳基恶唑烷-2-酮。由于胺、离子液体和NH 2-MIL-101的协同催化作用，它不仅在5次循环后表现出良好的稳定性和可恢复性，而且对底物表现出形状选择性。这种新型的双功能材料是一种很有前途的固体催化剂，用于N-芳基恶唑烷-2-酮的绿色合成。
A bifunctional heterogeneous catalyst was designed and synthesized, denoted DMEDA/IL–NH2-MIL-101. The structure and physical-chemical characterization of DMEDA/IL–NH2-MIL-101 and its precursors were characterized by SEM, N2adsorption-desorption, XPS, FT-IR, PXRD, elemental analysis, and TGA techniques. The date showed that the two catalytic components of N, N-dimethylethylenediamine (DMEDA) and 1-butyl-3-methylimidazolium bromide (BmimBr) were chemically immobilized in NH2-MIL-101 nanocages. The amine of DMEDA was grafted onto carrier NH2-MIL-101 by N–Cr coordinate covalent bonds and the ionic liquid of BmimBr (IL (Br−)) was anchored in the NH2-MIL-101 nanocages by ‘ship-in-a-bottle’ method, in which the amidogen of NH2-MIL-101 condensed with N, N-carbonyldiimidazole (CDI) firstly, and then alkylated with 1-bromo butane. This novel heterogeneous catalyst with two different active sites can efficiently catalyze the synthesis of N-aryl oxazolidin-2-ones from carbon dioxide (CO2), epoxides, and anilines in one-pot under mild solvent-free conditions. It not only showed good stability and recoverability after five cycles but also exhibited shape selectivity for the substrate due to the synergic catalysis of amine, ionic liquid, and NH2-MIL-101. This novel bifunctional material is a promising solid catalyst for the green synthesis of N-aryl oxazolidin-2-ones.
