Fe3O4@SiO2@APTMS@Glu-His@Cu complex was prepared from modification of ironoxide nanomagnet particles with (3-aminopropyl) trimethoxysilane (APTMS) and glutaraldehyde–histidine Schiffbase followed by complexation with Cu(I) salt. Characterization of this complex was carried out by means of FTIR, XRD, SEM, TEM and VSM techniques. The complex was found to successfully catalyze the oxidative homocoupling of phenylacetylene
