NiFe2O4@PPA-DABCO: A novel magnetically separable bifunctional nanocatalyst for the synthesis of 2,2´-(Arylmethylene) bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one) derivatives

This study introduces a novel magnetically separable NiFe₂O₄@PPA-DABCO magnetic nanocomposite catalyst. The catalyst is used to synthesize 2,2´-arylmethylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one) derivatives via a condensation reaction of aryl aldehydes and dimedone in ethanol at ambient conditions. The catalyst was examined by FTIR, XRD, SEM, EDS, TGA-DTA, and XPS analysis. This environmentally friendly methodology affords numerous benefits, such as a mild reaction condition, shorter reaction times, excellent yield, and use of green solvent. The catalyst can be recycled for six cycles without significantly affecting catalytic activity and product yield.

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
