In this study, ZnFe2O4 nanoparticles (NPs) were prepared by a hydro/solvothermal method, and their structures were characterized by infrared, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy and X‐ray diffraction analyses. These ZnFe2O4 NPs were used in the synthesis of new bis‐Schiff bases by condensation of hydroxyl‐substituted...

... Furthermore, these derivatives represent an important class of organic compounds, especially in the medicinal and pharmaceutical fields (Murtaza et al., 2014). It is well known from the literature that Schiff bases display excellent biological properties, such as antioxidant and analgesic (Karrouchi et al., 2016), antibacterial and cytotoxic (Maaref et al., 2020), antidiabetic (Karrouchi et al., 2022) and anti-inflammatory activities (Rana et al., 2012). These derivatives are also used as corrosion inhibitors, which relies on their ability to spontaneously form a monolayer on the surface being protected (El Arrouji et al., 2020). ...
Supporting information: this article has supporting information at journals.iucr.org/e Crystal structure and molecular docking study of diethyl 2,2 0 0 0-({[(1E,1 0 0 0 E)-(hydrazine-1,2-diylidene)-bis(methanylylidene)]bis(4,1-phenylene)}bis(oxy))-diacetate The title Schiff base, C 22 H 24 N 2 O 6 , adopts an E configuration. The molecule is planar, the mean planes of the phenyl ring system (r.m.s deviation = 0.0059 Å) forms a dihedral angle of 0.96 (4) with the mean plane of the phenyl ring moiety (r.m.s deviation = 0.0076 Å). In the crystal, molecules are linked by weak intermolecular C-HÁ Á ÁO and C-HÁ Á ÁN hydrogen bonds into chains extending along the c-axis and b-axis directions, respectively. A molecular docking study between the title molecule and 5-HT2C, which is a G protein receptor and ligand-gated ion channels found in nervous systems (PDB ID: 6BQH) was executed. The experiment shows that it is a good potential agent because of its affinity and ability to stick to the active sites of the receptor.
... Condensation reaction is among those chemical activities for which devising a new environmentally friendly catalyst could potentially provide an approach for dealing with the aforementioned challenges. Upon our previous study on synthesis of organic compounds by nanoparticles [26][27][28][29], the scope of the present work was to achieve the multi-component pyrano [2, 3-d] pyrimidines by using NiO nano powders as a green, environmentally friendly catalyst (Scheme 1). ...
In this paper NiO nanoparticles are utilized for effective strengthening of annulated pyrano [2, 3- d] pyrimidine synthesis through primary Knoevenagel, the following Micheal and ultimate heterocyclization reactions of aldehyde, malononitrile and barbituric acid. The NiO nanoparticles characteristics are identified through using advanced techniques like IR, UV, EDX, XRD, SEM and TEM. The nano-NiO particles are mostly of below < 100 nm sizes with uniform sphere shapes. The adopted approach is advantages due to its simple processing, relatively short reaction time, often good to high average yields, convenient workability, and environmental friendliness.
In the present study, the SrCO3@montmorillonite nanocomposite was synthesized by loading Sr(NO3)2 on natural bentonite using a controlled and facile microwave method. The SrCO3@montmorillonite nanoparticles characteristics are identified using advanced techniques such as infrared spectroscopy (IR), energy‐dispersive X‐ray analysis (EDX), X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and pore size distribution analysis. Crossed-aldol condensation of an aromatic aldehyde with cycloalkanone in the presence of these nanoparticles produced α, ά-bis(substituted-benzylidene) cycloalkanones in good yields without using any solvent. The present method is operationally simple and dosed not use organic solvent, which makes the process environmentally benign.
