| چکیده مقاله |
| Nowadays, heterogeneous catalysts have attracted much attention from scientists due to their easy separation and recycling. Metal-organic frameworks (MOFs) are crystalline porous materials composed of metal ions bonded to organic ligands. They possess properties such as extremely high surface area, high porosity, and remarkable thermal and chemical stability, which provide ideal substrates for the selective adsorption, storage, and release of various species due to their tunable pore sizes and tunable structures [1]. These materials have found wide applications in gas and energy storage, separation, sensing, and heterogeneous catalysis. In addition to enhancing catalytic performance, MOFs allow the design of versatile active sites and improved product selectivity, and their recyclability and compatibility with heterogeneous systems make them attractive candidates for innovative industrial and green applications [2-3]. In this study, based on the properties of these porous structures, a Ti-based MOF catalyst was synthesized and further modified with ionic liquid groups to be used for the synthesis of nicotinonitrile derivatives. Furthermore, as far as possible, the materials were synthesized using an optimized method suitable for increasing the efficiency and achieving pure products (Scheme 1). The anomeric based oxidation driving force is also used in the suggested reaction mechanisms. |
