NH2-coordinately immobilized tris(8-quinolinolato)iron onto the silica coated magnetite nanoparticle: Fe3O4@SiO2-FeQ3 as a selective Fenton-like catalyst for clean oxidation of sulfides

Fe3O4@vitamin B1 as a sustainable superparamagnetic heterogeneous nanocatalyst promoting green synthesis of trisubstituted 1,3‐thiazole derivatives

“…[17][18][19] Multicomponent reaction-based synthetic methodology is currently gaining more importance in the preparation of organic molecules. [20,21] As a part of our ongoing research and in continuation of earlier work, [22][23][24][25] herein we report Fe 3 O 4 @vitamin B 1 MNPs as a catalyst in the one-pot reaction between arylglyoxals monohydrate (1), cyclic 1,3-dicarbonyls (2) and thiobenzamides (3) under aqueous conditions at 80°C for the preparation of trisubstituted thiazole derivatives (Scheme 1).…”

Fe3O4‐supported Schiff‐base copper (II) complex: A valuable heterogeneous nanocatalyst for one‐pot synthesis of new pyrano[2,3‐b]pyridine‐3‐carboxamide derivatives

“…[11][12][13][14][15][16] Among these NPs, nanometal oxides such as Fe 2 O 3 , Fe 3 O 4 , TiO 2 , Al 2 O 3 , ZnO, etc. [18][19][20][21][22][23][24][25][26][27] Magnetic nanoparticles (MNPs) have recently received considerable attention both as solid support materials for a variety of homogeneous catalysts and as nanocatalysts in organic synthesis owing to their numerous benefits such as high stability, facile separation by external magnetic field, easy preparation and functionalization, and environmental benignity, as well as high surface area providing highly active sites on the particle surface and high loading capacity. [17] However, these nanoparticles suffer from difficult separation from the reaction mixtures by conventional separation methods such as filtration due to their nanometer scale (especially below 100 nm).…”

Synthesis of a highly active amino‐functionalized Fe3O4@SiO2/APTS/Ru magnetic nanocomposite catalyst for hydrogenation reactions

“…Significant attention has been focused on amino functionalization, because amino groups are well known to stabilize metal nanoparticles against aggregation during catalytic reactions . (3‐Aminopropyl)triethoxysilane (APTS) has been grafted on the surface of silica shells, where the amino groups of APTS can act as robust stabilizers for supporting metal nanoparticles, thus increasing reusability . Amino‐functionalized Fe 3 O 4 @SiO 2 shows excellent catalytic activity in the selective oxidation of alcohols and the Suzuki reaction .…”
