Glycerol Cu(II) Complex Supported on Fe3O4 Magnetic Nanoparticles: A New and Highly Efficient Reusable Catalyst for the Formation of Aryl-Sulfur and Aryl-Oxygen Bonds

Copper supported silica-based nanocatalysts for CuAAC and cross-coupling reactions

“…These catalysts are inexpensive and best for the production of valuable ethers, which are essential and starting materials in the synthesis of pharmaceutical, biological, cosmetic, and natural products. [189][190][191] A heterogeneous green Fe 3 O 4 @SiO 2 -glycerole-Cu (II) (33) catalyst was efficiently synthesized by Ashraf et al 192 To the mixture of CH 3 OK and THF, as-prepared Fe 3 O 4 @SiO 2 MNP 193 was added and stirred for 1 h. To this solution, anhydrous dioxane was added and heated to 95 °C. Next, glycerole was slowly added over about 15 h and the whole reaction mixture was stirred for 1 h to get Fe 3 O 4 @SiO 2 -glycerole.…”

Pd(0)‐guanidine@MCM‐41: a very effective catalyst for rapid production of bis (pyrazolyl)methanes

“…[1][2][3][4][5][6][7] Its central aim is the control of chemical reactions by changing the size, dimensionality, chemical composition and morphology of the reaction center, and by changing the kinetics using nanopatterning of the reaction centers. [8][9][10][11][12] Nanoparticles can substitute conventional materials, and serve as active and stable heterogeneous catalysts or as support materials for various catalytic groups. [13][14][15][16][17][18] Due to their small sizes, catalytic-active nanoparticles have higher surface areas and increased exposed active sites, and thereby improved contact areas with reactants, akin to those of homogeneous catalytic systems.…”

L‐lysine‐Pd Complex Supported on Fe3O4MNPs: a novel recoverable magnetic nanocatalyst for Suzuki C‐C Cross‐Coupling reaction

“…[65][66][67][68][69] The development of hybrid inorganic-organic nanocomposite catalyst has gained considerable attention due to its process ability, multifunctionality, and the potential large-scale production. [70][71][72] Immobilization of the homogeneous catalysts on these nanocomposites as a solid support will aid the recovery of the catalyst and minimizing the pollution via simple magnetic decantation. [73][74][75][76][77][78][79] In this sense, the combination of the magnetic property of the magnetic nanoparticles (MNPs) and the molecular recognition of a specific organic structure exposed their distinct advantages.…”
