چکیده	Magnetic nanoparticles (MNPs) would be widely designed and used as novel magnetically separated catalysts in organo catalysis. Based on their unique properties such as high activity, ability to be separated easily with magnets and reused several times in reaction, we have designed and synthesized various MNPs functionalized catalysts and reagent, including (Fe3O4@Nico@ClSO3H), (Fe3O4@SiO2@(CH2)3-Iminodiacetic acid@Cu) and (Fe3O4@Si(CH2)3-Sulfonamide-Cl). The mentioned magnetic nano catalysts and reagent would be successfully synthesized and fully characterized by TG, IR, EDX, XRD and SEM techniqes. The designed nano particles were applied as nano magnetic catalysts and reagent in some organic compounds synthesis such as; 1-carbamato-alkyl-2-naphthols, dihydropyrano[2,3-c]pyrazoles and 4,4'-(arylmethylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol)s. Moreover, we have synthesized and characterized a nanoorgano catalyst with nitrilo triacetic acid namely nitrilo triacetic acid sulfonic acid chloride. This compound, as an organic acid catalyst has advantages such as high stability, availability of the catalyst, metal-free nature and low toxicity. Because of its fully organic structure and in absence of metals, this compound can be considered as a green and eco-friendly catalyst which does not make any pollution to the environment. By the use of such methods like mass spectrometry (Mass), infrared (IR) and nuclear magnetic resonance spectroscopy (NMR), the structure of this compound would be specified. Additionally, using spectral data, such as X-ray diffraction (XRD), energy dispersive X-ray (EDX) and scanning electron microscopy (SEM) structure and size of this novel nano catalyst are investigated. Besides, by utilizing the thermal gravimetric analysis (TGA), we were able to determine that to what extent the temperature could be used of this catalyst in chemical reactions. Following synthesis and investigation of the structure of this nanoorgano catalyst of the referred me
