C–C and C–H coupling reactions by Fe₃O₄/KCC-1/APTPOSS supported palladium-salen-bridged ionic networks as a reusable catalyst

Abstract

This study investigates the potential application of an efficient, easily recoverable and reusable magnetically separable Fe3O4/KCC-1/APTPOSS nanoparticle-supported salen/Pd(ii) catalyst for C–C and C–H cross-couplings.

Functionalized Silicas for Metal‐Free and Metal‐Based Catalytic Applications: A Review in Perspective of Green Chemistry

“…With the use of 4‐aminoethylpiperidine during the sequential alkylations with cyanuric chloride, the grafting of organic dendrite molecules on silica is achieved . Sodium chloroacetate has been also used for the N‐alkylation with aromatic FS Different to the above reports, research group of S. M. Sadeghzadeh has carried out the nucleophilic substitution on eight chlorine sites of chloropropyloctasilsesquioxane using APTES and successively, the obtained product is anchored on silica …”

Biomedical applications of dendritic fibrous nanosilica (DFNS): recent progress and challenges

“…Different techniques have been the main methods for the characterization of DNFSs. For instance, to verify the synthesis of silica NP-based mesoporous materials, we can use Fourier transform infrared spectroscopy (FTIR), 54 X-ray diffraction (XRD) analysis, 55 transmission electron microscopy (TEM), 56 scanning electron microscopy (SEM), 37 atomic force microscopy (AFM), Brunauer-Emmett-Teller (BET) analysis, 57 dynamic light scattering (DLS), 37 thermogravimetric analysis (TGA), 50 X-ray photoelectron spectroscopy (XPS), 58 energy-dispersive X-ray uorescence spectroscopy (ED-XRF), 53 vibrating sample magnetometer (VSM), 59,60 solid-state 13C CPMAS, 61 and 29Si CPMAS NMR spectroscopy. 53,62 The functional groups of nanocomposites can be identied by FTIR, and XRD (used for the determination of the crystalline structure and the phase purity of modied silica NPs).…”

Chemoselective reduction of nitro and nitrile compounds using an Fe3O4-MWCNTs@PEI-Ag nanocomposite as a reusable catalyst

“…39,40 In addition, while there are interesting achievements with noble metal functionalized magnetic carbon nano/microtubes, for example, in catalysis and sensors, [41][42][43] other low dimensional nanocarbon scaffolds are actively pursued by the researchers, [44][45][46][47][48][49][50] and are going to nd application in energy materials. [51][52][53][54][55][56][57][58][59][60] Herein, we introduce Fe 3 O 4 -MWCNTs@PEI as a novel support for uniform dispersion of Ag NPs over its surface, and application of the Fe 3 O 4 -MWCNTs@PEI-Ag hybrid material as an efficient catalyst for chemoselective reduction of nitro and nitrile compounds to amines in aqueous solution under very mild and green conditions.…”
