Design, Synthesis, and Characterization of a Novel Magnetically Recoverable Copper Nanocatalyst Containing Organoselenium Ligand and Its Application in the A³ Coupling Reaction

In the present work, a novel heterogeneous catalytic system involving copper(I) complex of moisture- and air-stable organoselenium ligand supported on Fe3O4 nanoparticles modified by SiO2/aminopropyltrieethoxysilane was designed, synthesized, and characterized using various physicochemical methods inclusive Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometry, field emission scanning electron microscopy,...
