Esmaeilpour, Mohsen published the artcileFacile synthesis of 1- and 5-substituted 1H-tetrazoles catalyzed by recyclable ligand complex of copper(II) supported on superparamagnetic Fe3O4@SiO2 nanoparticles, Recommanded Product: 5-(4-(Trifluoromethyl)phenyl)-1H-tetrazole, the publication is Journal of Molecular Catalysis A: Chemical (2014), 18-29, database is CAplus.
A new method for preparing functionalized superparamagnetic Fe3O4@SiO2 possessing high saturation magnetization was reported. Magnetite particles were prepared by simple co-precipitation method in aqueous medium, and then Fe3O4@SiO2 nanosphere was synthesized by using nano Fe3O4 as the core, TEOS as the silica source and polyethylene glycol (PEG 1000) as the surfactant. Then, the silica-coated Fe3O4 nanoparticles were covered with ligand complex of Cu(II). The functionalized magnetic core-shell nanoparticles (MNPs) were investigated by Fourier transform IR spectroscopy, transmission electron microscopy, SEM, X-ray diffraction, thermogravimetric anal., dynamic light scattering and N2 adsorption/desorption. Also, its Cu content was determined by inductively coupled plasma (ICP) analyzer. Then, the immobilized copper complex was used as an efficient catalyst for synthesis of 1- and 5-substituted 1H-tetrazoles from nitriles and amines in good to excellent yields. The results show that the supported catalyst could be conveniently recovered through the use of an external magnetic field and reused for subsequent reactions for at least 6 times with less deterioration in catalytic activity.
