Cu(ii) immobilized on poly(guanidine-sulfonamide)-functionalized Bentonite@MgFe2O4: a novel magnetic nanocatalyst for the synthesis of 1,4-dihydropyrano[2,3-c]pyrazole

“…Regarding the growing interest of organic chemists in nanocomposites, several studies have been conducted on these materials due to the unique surface and physical properties of these heterogeneous catalysts in different organic reactions. [26][27][28][29][30][31] Nowadays, magnetic nanoparticles, which are one of the most inuential factors in the nanomaterial family, have been extensively employed in different sciences, consisting of drug shipping, sickness recognition, water desalination, and chemical catalysis. 3,31 Among magnetic nanoparticles, nanophase spinel ferrites with superparamagnetic behavior are presently utilized in drug transport, microwave devices, catalytic activity, and magnetic imaging.…”

Catalytic application of a novel melamine–naphthalene-1,3-disulfonic acid metal–organic framework in the synthesis of β-acetamido ketones

“…Herein, regarding the interesting properties of Zr-based MOFs and pursuing our interest in porous substances as catalysts in MCRs, [76][77][78][79][80][81][82][83][84][85] we aimed to design and prepare a stable multifunctional Zr-MOF (UiO-66-Mel-NHC 10 H 5 (SO 3 H) 2 ) consisting of a melamine-sulfonic acid covalently bonded to the UiO-66-NH 2 (Scheme 1). The obtained MOF was prepared through PSM of the UiO-66-NH 2 in the following two steps: (I) covalent hybridization of cyanuric chloride and (II) functionalization with 7-aminonaphthalene-1,3-disulfonic acid.…”

Ni(ii) immobilized on poly(guanidine–triazine–sulfonamide) (PGTSA/Ni): a mesoporous nanocatalyst for synthesis of imines

“…A careful selection of monomers and templates plays an essential role in these materials' electronic, chemical, and topological properties. 6,[34][35][36][37] In general, nitrogenous ligands' incorporation into a polymer chain is an effective strategy to benet simultaneously from the excellent characteristics of porous polymers and the common properties of ligands of nitrogen, thereby establishing other functionalities.…”
