1H-Phenanthro[9,10-d]imidazole functionalized iron(ii,iii)oxide nanoparticle for magnetically recoverable nanocatalyst for monoalkylation of cyclam

Magnetically recoverable nanocatalyst was synthesized by covalent binding of 1H-phenanthro[9,10-d]imidazole-derived compound and silica coated iron(II,III)oxide magnetic nanoparticles functionalized by (3-chloropropyl)trimethoxysilane (CPTMS). Characterization of the prepared nanocatalyst was accomplished with FT-IR, XRD, TG/DSC, VSM, STEM, FE-SEM, EDX techniques. 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 less side-product formations and also six-times recyclability of nanocatalyst as well as reusability.
