“…At this time, the conversion and the selectivity of 3-acylindole would increase with the increasing of molar ratio. In a heterogeneous reaction, mass-transfer limitation might have a significant effect on the reaction rate in the reaction system [14]. However, when the molar ratio between indole and benzoyl chloride rose to a certain value (1:3), because of the presence of a large amount of benzoyl chloride, the benzoyl chloride would have a solvent effect and change the distribution of indole between catalyst surface and liquid phase [27].…”

“…In recent years, because of their unique properties such as unsaturated metal active sites, easy functionalization, and large surface area, they are widely used in the field of catalysis [12,13]. Nguyen et al [14] used the metal active site of Zn in IRMOF-8 to catalyze a Friedel-Crafts acylation reaction of toluene and benzoyl chloride. After 6 h of reaction, the conversion of toluene reached 95.0% and the IRMOF-8 catalyst could be reused without significant degradation of its catalytic activity.…”

Metal-organic framework MIL-53(Al) was synthesized by a solvothermal method using aluminum nitrate as the aluminium source and 1,4-benzenedicarboxylic acid (H 2 BDC) as the organic ligand. The structure of samples was characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The catalytic activity and recyclability of MIL-53(Al) catalyst for the Friedel-Crafts acylation reaction of indole with benzoyl chloride were evaluated. The reaction conditions were optimized and a reaction mechanism was suggested. The results showed that the MIL-53(Al) catalyst exhibited good catalytic activity and recyclability for the Friedel-Crafts acylation reaction. When the molar ratio of indole and MIL-53(Al) catalyst was 1:0.06 (n 1 :n catalyst ), the molar ratio of indole and benzoyl chloride was 1:3, and the solvent was dichloromethane, the conversion of indole could reach 97.1% and the selectivity of 3-acylindole could reach 81.1% at 25 °C after 8 h. The catalyst can be reused without significant degradation in catalytic activity. After the catalyst was reused five times, the conversion of indole was 87.6% and the selectivity of 3-acylindole was 79.5%.

“…An appropriate synthesis method may result in MOFs with solid structures, high crystallinity, and high thermal stability. MOFs have been widely used in het-erogeneous catalyses [2][3][4][5], drug deliveries [6,7], gas storages [8,9], photocatalysis [10][11][12], gas sensors [13,14], and separations [15]. An improvement in synthetic procedures is of highly importance in producing MOFs with high energy efficiency.…”

A zirconium metal-organic framework (MOF) of DUT-52 (DUT: Dresden University of Technology) was synthesized herein by reacting zirconium tetrachloride (ZrCl4) and 2,6-naphthalenedicarboxylic acid (H2NDC) in DMF under microwave heating at 115 oC for 25 min. This synthetic procedure was more efficient than a solvothermal method, by which a long thermal exposure (24 h) of 100-150 oC was required to produce the same MOF. The MOF has a thermal stability of 560 °C, prior to partial loss of interconnected 2,6-naphthalenedicarboxylate (NDC) linkers at some structure building units (SBU). Crystallinity of this DUT-52 was ca. 77 %, which was the same as one synthesized solvothermally. Diffuse Reflectance UV-Vis spectra revealed an absorption at λex of 287 nm, which was equivalent to a bandgap energy of 4.32 eV. Electron excitations of this DUT-52 at 275 and 300 nm gave emission wavelength of 433 nm (a purple region), indicating a prospective use of DUT-52 as a photoluminescent material.

“…[18] In general, these reactions are catalyzed by homogeneous catalysts such as AlCl 3 , FeCl 3 , and ZnCl 2 , which unfortunately suffer from serious problems such as high moisture sensitivity, difficult separation, and undesirable environmental impact. [19] Towards the development of environmentally benign process for the production of aromatic ketones, the synthesized hierarchical ZSM-5 zeolites were applied and proved to be efficient heterogeneous catalysts for the Friedel-Crafts acylation of anisole.…”

“…Additionally, the combination of a good accessibility and strong acidity in hierarchical zeolite should also be responsible for the improved catalytic properties as compared with amorphous Al-MCM-41. [3,17,19] Finally, the reusability of hierarchical zeolites was studied, and limited activity loss in the anisole conversion was found after the second cycle ( Table S2 in the Supporting Information).…”
