A Ligand from Amino Acides Gapped Mn Immobilized on Multi-Walled Carbon Nanotube:A New Nanocatalyst for Coupling Reaction

In this research, a Mn transition metallic complex on CNT has been designed and utilized as an effective,recoverable, and thermally stable heterogeneous nanocatalyst in the formation of the C-C bond. Also, thesynthesis of amino benzyl naphthol derivatives was performed by the three-component reaction of couplingfrom aromatic aldehydes, type II amines, and ۸-hydroxyquinoline in the presence of the CNT- A ligand fromamino acides -Mn nanocatalyst under reflux conditions. Finally, the nature of catalysts was studied by usingsome techniques such as the Fourier transform infrared spectrum, energy-dispersive spectroscopy, hot filtrationtest, transmission electron microscopy, scanning electron microscopy, X-ray diffraction, inductively coupledplasma optical emission spectrometry, and N۲ adsorption-desorption (BET). The synthesized heterogeneouscatalysts showed perfect catalytic activity and also good recyclability in the coupling reaction. They could bereused at least for five consecutive cycles without significant loss of their catalytic activities
