    Résumé The p-dodecylbenzenesulfonic acid (DBSA) has been successfully applied as an efficient acidic catalyst for the microwave-assisted synthesis of a series of 14-aryl- or alkyl-14H-dibenzo[a,j]xanthenes (3a-m) via a one-pot condensation-cyclization reaction of β-naphthol with various aliphatic or aromatic aldehydes under solvent-free conditions. Operational simplicity, short reaction times, excellent yields and environmentally-benign conditions are other advantages of this protocol.

    resulting MPILs show excellent catalytic activity for condensation reaction and Knoevenagel condensation. The kinetic study reveals that the excellent catalytic activity of MPILs is attributed to the synergistic catalysis of mesoporous confinement effect and hydrogen proton from MPILs, albeit with mass transfer resistance produced by mesoporous channels. Further, the catalyst can be recovered using an external
    介孔聚(离子液体)(MPIL)的制备对于多相催化剂的设计至关重要,而传统方法很难获得具有明确定义的介孔结构和独特功能的材料。在这里,成功制备了具有明确介孔结构的HClO 4官能化MPIL,其中烯烃改性的Fe 3 O 4纳米颗粒作为结构增强剂在介孔结构形成中起着至关重要的作用。MPIL以N 2为特征吸附/解吸,扫描电子显微镜(SEM),透射电子显微镜(TEM),傅立叶变换红外光谱(FT-IR),X射线衍射(XRD),热重分析(TGA)和振动样品磁强(VSM),结果表明,MPIL具有中等的表面积,明确的介孔率,丰富的活性离子中心以及有效的磁回收率。所得的MPIL对缩合反应和Knoevenagel缩合显示出极好的催化活性。动力学研究表明,尽管具有介孔通道产生的传质阻力,但MPIL的优异催化活性归因于介孔约束作用和MPIL的氢质子的协同催化作用。进一步,可以使用外部磁场回收该催化剂,并重复使用至少
