In recent years, the improvement in nanotechnology led to an increasing insist for multifunctional materials owing to simplicity in operation, remarkable recyclability, high surface area of catalysts and ecofriendly nature1. In this regard, solid catalysts and magnetic composite nanoparticles are interesting for industrial and biomedical applications and, especially, in catalysis studies as a magnetically separable catalyst2. Different experimental methods for the synthesis of spinel ferrites have been reported in the literatures, such as: sol-gel, electrodeposition, reaction sintering, mechanochemical, single step solution combustion, co-precipitation, thermal decomposition, hydrothermal, electrochemical, and solvent deficient3,4. Among these procedures, co-precipitation method is an easy, versatile, and low-cost method for the preparation of FeAl2O4 nanoparticles5. In the development of greener and sustainable processes for the organic synthesis, Arginine-Ni organometallic complex supported on Hercynite magnetic nanoparticles FeAl2O4@ Arginine-Ni MNPs was prepared by simple procedure and applied as catalyst for the preparation of 2,3- dihydroquinazolin-4(1H)-one derivatives and polyhydroquinoline derivatives using expensive, green and available materials (Fig. 1).
