The triazole-thiol-functionalized Mn-complex and its catalytic performance

Abstract

The novel magnetic triazole-thiol-functionalized Mn-complex was obtained by preparation of the Fe₃O₄ magnetic nanoparticles, coating of Fe₃O₄ MNPs with tetraethyl orthosilicate, functionalization with both 3-chloropropyltrimethoxysilane (CPTMS) and 1-H-1,2,4-triazole-3-thiol (TT) ligands, and further complexation with manganese acetate. Then, the supported Mn catalyst (Fe₃O₄@SiO₂@CPTMS@TT@Mn) was characterized by various methods (FT-IR, XRD, EDX, ICP, SEM, SEM-mapping, SEM-Histograms, TEM, TGA-DTA, VSM, and BET) and used as a heterogeneous nano-catalyst for the synthesis of diverse N-benzylated cyanamides from the reaction of various aryl cyanamides with benzyl bromide and K₂CO₃ in acetonitrile at 60 °C in appropriate times.
