摘要

Magnetically recoverable nanocatalyst was synthesized by covalent binding 1 H-phenanthro[9,10-d]imidazole-derived compound and silica-coated Fe₃O₄ magnetic nanoparticles functionalized by (3-chloropropyl)trimethoxysilane (CPTMS). FT-IR (Fourier Transform Infrared Spectroscopy), XRD (X-ray Diffraction), TG/DSC (Thermogravimetric Analysis / Differential Scanning Calorimetry), VSM (Vibrating Sample Magnetometry), STEM (Scanning Transmission Electron Microscopy), FE-SEM (Field-Emission Scanning Electron Microscopy), EDX (Energy-Dispersive X-ray Spectroscopy) techniques were used for characterizations. Monoalkylation reaction of 1,4,8,11-tetraazamacrocycle with the 4-(bromomethyl)benzoic acid to give 4-((1,4,8,11-tetraazacyclotetradecan-1-yl)methyl)benzoic acid was performed by using magnetic nanocatalyst MNP1 that ensures short reaction times with high yields and fewer side-product formations and also six-times recyclability of nanocatalyst as well as reusability.
