In this paper, a new nano-size ionic liquid (nIL) has been synthesized from D-phenylalanine and oxalic acid (D-Phe-OX) via a simple procedure. The obtained nIL has been characterized by the fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDAX), thermogravimetric analysis (TGA), nuclear magnetic resonance spectroscopy (1</sup...

A synergetic effect of nanocatalyst and ultrasonic irradiation was examined for the synthesis 4H-chromenes from benzaldehyde, cyclohexanone, malononitrile. It observed this contributory improved reaction that used highly pure products in short times highest yields. The nanocomposite includes guanidine anchored on to magnetic NiFe2O4 nanoparticles were as active base sonication compounds. produc...

Grafting and stabilization of metal complexes for increasing catalytic activity have remained an enormous challenge in the arena. However, designing a system with complementary properties including high surface area, loading, easy separation offers promising route efficient utilization magnetic material various applications. Herein, novel core–shell nanosphere catalyst (Fe3O4@C/KP23@MnCl2) was ...

Industrial effluents contain a wide range of organic pollutants that present harmful effects on the environment and deprived communities with no access to clean water. As this matter is resistant conventional treatments, Advanced Oxidation Processes (AOPs) have emerged as suitable option counteract these environmental challenges. Engineered iron oxide nanoparticles been widely tested in AOPs ca...

A synergetic effect of ultrasonic irradiation and yolk–shell nanocatalyst was examined for the synthesis spirooxindoles from isatin, malononitrile cyclohexanone. It found this contributory can be accelerated desired reaction toward obtaining highly pure products in excellent yields short times. The contains melamine anchored onto magnetic Fe3O4 nanoparticles were applied as active base catalyst...

In the present study, we carried out chemical synthesis and characterization of Fe3O4@PEG-Au as a magnetic nanocomposite in aqueous solution by chemical co-precipitation of Fe3+ and Fe2+ ions and encapsulated by poly (ethylene glycol) (PEG) in order to enhancing hydrophilicity, biocompatibility and immobilizing gold ions in the presence of NaBH4 as a reducing agent. Nanostructures were characte...

In this work, various 3-cyano-4-aryl-4H-pyran derivatives were prepared efficiently through a one-pot,multicomponent synthesis between aromatic aldehyde, malononitrile and acetophenone derivativesor ethyl acetoacetate using Fe3O4/EDTA magnetic nanocatalyst and ethanol as solvent. The reactionswere completed at room temperature in 10 min using 5 mg of catalyst and 2 mL of solvent to prepare1 mmo...

The selective hydrogenation of chalcone to dihydrochalcone under atmospheric hydrogen pressure is investigated using a thermoregulated phase-transfer ruthenium nanocatalyst, representing the first nanocatalyst used for this reaction. Under optimal conditions, conversion into and selectivity are 98% &gt;99%, respectively. catalyst can be easily separated from product recycled three times without...
