Annotatsiya

A novel tribromide nanocatalyst was successfully fabricated via the heterogenization of tribromide ion on the surface of silica-coated magnetic nanoparticles modified with N2,N4,N6-tris(aminomethyl)-1,3,5-triazine-2,4,6-triamin [Fe3O4@SiO2-tris(triazine-triamine)-Br3] and was well characterized by Fourier-transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-Ray Analysis (EDX), vibrating-sample magnetometer (VSM), X-ray diffraction analysis (XRD) and Thermogravimetric analysis (TGA) spectroscopic techniques. TEM and SEM analysis confirmed that the typical silica shell thickness was assessed to be around 20 nm. The as-fabricated Fe3O4@SiO2-tris(triazine-triamine)-Br3 nanomaterial was shown high catalytic activity in the multicomponent synthesis of highly substituted piperidines and polyhydroquinolines. Recycling experiments revealed that the Fe3O4@SiO2-tris(triazine-triamine)-Br3 could be easily recovered by a simple magnetic separation and recycled at least 7 times without deterioration in catalytic activity.
