  3. Abstract:
  4. A copper catalyst has been explored as an efficient and recyclable catalyst to effect Sonogashira and Suzuki cross-coupling reactions. After modification of 2-(((piperazin-1-ylmethyl)imino)methyl)phenol (PP) on the surface of amorphous silica-coated iron oxide (Fe3O4@SiO2@Cl) magnetic core–shell nanocomposite, copper(II) chloride was employed to synthesize the Fe3O4@SiO2@PP-Cu catalyst, affording a copper loading of 1.52 mmol g−1. High yield, low reaction times, non-toxicity and recyclability of the catalyst are the main merits of this protocol. The catalyst was characterized using Fourier transform infrared, X-ray photoelectron, energy-dispersive X-ray and inductively coupled plasma optical emission spectroscopies, X-ray diffraction, scanning and transmission electron microscopies, and vibrating sample magnetometry.
