The present study described design, preparation and characterization of a new magnetic nanocomposite based on polyvinyl alcohol (PVA) as a non-toxic, water-soluble, high mechanical stable and low-cost polymer. Fourier transform infrared (FT-IR) spectroscopy, field-emission scanning electron microscopy (FE-SEM) image, transmission electron microscope (TEM) image, X-ray diffraction (XRD) pattern, energy-dispersive X-ray (EDX) analysis and thermogravimetric (TG) analysis were used to describe the morphological, chemical and physical properties of the prepared nanocatalyst. All these results confirmed the successful synthesis of Fe3O4@PVA-SO3H. This heterogeneous nanocatalyst was then successfully used for the synthesis of α-aminonitrile derivatives by starting from an aldehyde, an aniline and trimethylsilyl cyanide (TMSCN). High efficiency, green chemistry properties, simple and easy separation are the specific properties of this nanocomposite. Fe3O4@PVA-SO3H can be derived out by an external magnet and reused ten times without any changes in its structure.

, p. 4821 - 4829 (2015/06/16)
In this research, nano magnetic sulfated zirconia was prepared and characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) measurements and vibrational sample magnetometry (VSM). Its catalytic activity was investigated for the one-pot three component green synthesis of α-aminonitriles using various aldehydes and ketones at room temperature in ethanol. This protocol has various advantages such as: simple work-up, short reaction time, high product yields and easy recovery and reusability of the catalyst.
