“…Metal-organic frameworks (MOFs) are a series of rapidly developing materials with three-dimensional porous structure, large specific surface area and varied composition [1], which provide potential applications in catalysis [2][3][4], energy storage [5][6][7] and separation [8][9][10]. MOFs are an important type of catalytic component for composite materials with multifunctional properties, and their catalytic performance has attracted a great deal of research attention.…”

Core–shell nanocomposites with a catalytic metal-organic framework (MOF) shell are more effective and stable than bare MOF. We have successfully designed an effective heterogeneous catalyst for the synthesis of benzimidazole by integrating acidic catalytic activity, and promoted the aerobic oxidation and magnetic recyclability of core–shell nanocomposite Fe3O4@SiO2@UiO-66. The Fe3O4@SiO2 core is encapsulated by the in situ-grown UiO-66 shell, and the UiO-66 shell retains the porous structure and crystallinity of UiO-66 with abundant exposed Lewis acid sites. It shows high catalytic ability for the synthesis of various benzimidazoles through the acid-catalyzed condensation and aerobic oxidation with in situ oxygen. The Fe3O4@SiO2 core provides magnetic recyclability of Fe3O4@SiO2@UiO-66, and maintains high catalytic ability and stability over six cycles.

“…Indeed, the quinazolin-4(3H)-one derivatives were previously synthesized by the thermolysis of 3-arylideneamine-1,2,3-benzotriazine-4-ones in paraffin oil at 300°C 13 or condensation of anthranilamide with aldehydes, ketones or isatoic anhydride with ammonium acetate using various catalysts such as ionic liquid [BDBIm]Br 14 , Sc(OTf)3 15 , TiCl4-Zn 16 , FeCl3.6H2O 17 , Ni(NO3)3.3H2O 18 , CuCl2 in ethanol 19 , p-toluenesulfonic acid/DDQ 20 and SbCl3 under microwave irradiation 21 . Recently different catalysts were reported, such as sulfated MOF-808 22 , H3PO3 23 , FeCl3.6H2O-H2O/PEG-400 24 , Cu@PEI-MGO 25 and Pd(PPh3)4 26 .…”

Comparative study between the Titanium Phosphate TiP2O7 and the Phosphate Fertilizers in the catalysis of the Quinazolin-4(3H)-one derivatives synthesis

A simple and efficient method for the synthesis of quinazolin-4(3H)-one derivatives via condensation of anthranilamide with aromatic aldehyde catalyzed by monoammonium phosphate (MAP), diammonium phosphate (DAP), and triple superphosphate (TSP), were developed. The modification of these three phosphate fertilizers using titanium tetrachloride (TiCl4) has increased their catalytic efficiency. The prepared titanium phosphate (TiP2O7) was characterized using microscopic and spectroscopic methods, namely X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), and infrared spectroscopy (IR). The TiP2O7 was applied for the first time as a heterogeneous catalyst in quinazolin-4(3H)-ones synthesis. High yields and short reaction times were observed in the determined optimal condition (solvent nature, volume, and catalyst amount). This study shows that the TiP2O7 presents an exciting catalytic activity and long-term durability compared to those of MAP, DAP, and TSP.

“…Glycerol or propane-1,2,3-triol 1 is now produced in large quantities as a byproduct in many industries [3,4,5]. The large-scale production of biodiesel from fats, where glycerol is a waste product, has made glycerol a highly economic solvent and reactant [6,7,8,9,10,11,12]. This has attracted many researchers in the last two decades to find routes for converting this surplus into value added products [13,14,15,16,17,18,19,20,21,22,23,24].…”

The role of glycerol as a green bio-based solvent, reactant, and/or a catalyst in the synthesis of novel heterocycles, under pressure, is studied. Synthesis of novel quinolines in good yields using a new modified Skraup synthesis, utilizing glycerol and pressure Q-tubes, is demonstrated. Novel aniline trimers are prepared using glycerol, and substituted anilines under pressure, in acidic medium and water. Glycerol was employed as a catalyst and a green solvent in the synthesis of novel pyridazines 13a–c. The mechanisms of the reactions and the catalytic effect of glycerol in protic and aprotic media are fully discussed. The structures of the synthesized compounds were determined via X-ray crystallography and spectroscopic methods.
