Synthetic Application of Magnetic Nanocomposite Fe3O4@PEG-Au as a Heterogeneous and Reusable Nanocatalyst in The Suzuki Coupling Reactions
In the present study, we carried out chemical synthesis and characterization of Fe3O4@PEG-Au as a magnetic nanocomposite in aqueous solution by chemical co-precipitation of Fe3+ and Fe2+ ions and encapsulated by poly (ethylene glycol) (PEG) in order to enhancing hydrophilicity, biocompatibility and immobilizing gold ions in the presence of NaBH4 as a reducing agent. Nanostructures were characte...
متن کاملH2 storage in isostructural UiO-67 and UiO-66 MOFs.
The recently discovered UiO-66/67/68 class of isostructural metallorganic frameworks (MOFs) [J. H. Cavka et al. J. Am. Chem. Soc., 2008, 130, 13850] has attracted great interest because of its remarkable stability at high temperatures, high pressures and in the presence of different solvents, acids and bases [L. Valenzano et al. Chem. Mater., 2011, 23, 1700]. UiO-66 is obtained by connecting Zr...
متن کاملA Copper-Based Metal-Organic Framework as an Efficient and Reusable Heterogeneous Catalyst for Ullmann and Goldberg Type C-N Coupling Reactions.
A highly porous metal-organic framework (Cu-TDPAT), constructed from a paddle-wheel type dinuclear copper cluster and 2,4,6-tris(3,5-dicarboxylphenylamino)-1,3,5-triazine (H₆TDPAT), has been tested in Ullmann and Goldberg type C-N coupling reactions of a wide range of primary and secondary amines with halobenzenes, affording the corresponding N-arylation compounds in moderate to excellent yield...
