the preparation of 1-(α-aminoalkyl)-2-naphthols over magnesium schiff base complex supported on magnetite nanoparticles

Magnesium schiff base complex supported on magnetite nanoparticles (fe3o4@sio2 c3h6 magnesium schiff base complex) was designed and fully identified using different analyses including fourier transform infrared spectroscopy (ft-ir), energy-dispersive x-ray spectroscopy (eds), vibrating sample magnetometry (vsm), and scanning electron microscopy (sem). the presented supported nano-magnetite catalyst was tested as a novel and recyclable catalyst for the preparation of some 1-(α-aminoalkyl)-2-naphthols via the condensation reaction of 2-naphthol with various aromatic aldehydes and some amine compounds including piperidine, pyrrolidine and morpholine with acceptable results. simple work-up procedures, mild reaction condition, and the recyclability of fe3o4@sio2 c3h6 magnesium schiff base complex are the other advantages of this work.
