Abstract
A new complex of copper (II) was synthesized through the reaction of a Schiff-base, 4-(((2-hydroxyethyl)imino)methyl)phenol, with CuCl2·2H2O and, then, immobilization on SBA-15 support. Both immobilized and free copper complexes were characterized using different techniques such as FT-IR, elemental analysis (CHN), SEM, XRD and TEM, and were utilized as catalysts in one-pot azide-alkyne cycloaddition (AAC) reaction. Both catalysts showed high activity in conversion of various substrates to corresponding triazole compounds. The reaction was performed in water under mild condition and without any extra additives. The prepared catalyst was recovered and reused in 5 runs without any significant loss of activity.
