In this work, we report a new and recoverable catalyst by anchoring the Mn–Lysine complex on the surface of CoFe 2 O 4 magnetic nanoparticles through a simple, rapid and eco-friendly procedure. The successful synthesis of this nanostructure was confirmed by scanning electron microscopy, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction measurements and X-ray elemental mapping. The magnetic nanocatalyst exhibited excellent reactivity in the synthesis of 4,4′-(arylmethylene)-bis-(3-methyl-1-phenyl-1 H -pyrazol-5-ols) derivatives. Furthermore, the catalyst was conveniently separated by magnetic decantation from reaction mixture and recycled several times without significant loss of its activity. Graphic abstract We prepared a green and recoverable nanocatalyst for organic transformation.
