Abstract: Potassium fluoride impregnated on clinoptilolite nanoparticles (KF/CP NPs) have been explored to serve as an effective and inexpensive heterogeneous catalyst for the one-pot three-component Strecker synthesis of a variety of α-aminonitriles at room temperature in ethanol as a green solvent. KF/CP NPs have been synthesized using simple impregnation techniques in aqueous media from readily available inexpensive starting materials and displayed its initial catalytic activity even after five runs. The easy preparation and separation of catalyst, simple procedure, mild reaction conditions, and excellent yields of products render this method as an attractive sustainable option.

Abstract: A new multifunctional bimetallic nanocatalyst was prepared by immobilization of Cu/Ni-doped sulfated zirconium oxide on magnetic cadmium ferrite (CdFe2O4@SiO2@ZrO2/SO42?/Cu/Ni) and used as an efficient recyclable catalyst for one-pot as well as stepwise preparation of α-aminonitriles under mild conditions. The magnetic nanocatalyst was characterized by FTIR, TGA, VSM, XRD, EDX, FE-SEM, and TEM analyses. Also, the surface acidity of the catalyst was measured by pyridine adsorption assay. The catalyst possesses various active sites which could catalyst a variety of aromatic and aliphatic aldehydes to the corresponding α-amionitriles under moderate to high yields in the presence of aniline. Furthermore, transformation of ketones to the desired α-amionitriles and some bis-aminonitriles was also performed by this method. The catalyst could be readily recovered from the reaction mixture and reused for several times without significant loss of activity. Graphic abstract: A general and efficient method has been developed for transformation of a variety of aliphatic, aromatic aldehydes and ketones to the corresponding α-aminonitriles using a multifunctional recyclable CdFe2O4@SiO2@ZrO2/SO42?/Cu/Ni nanocatalyst.[Figure not available: see fulltext.]

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.
