Isoxazole-5-(4H)-one derivatives have garnered considerable attention owing to their wide range of pharmacological activities, such as anti-inflammatory, analgesic, antimicrobial, and antitumor properties. The multicomponent synthesis of 3,4-disubstituted-isoxazole-5-(4H)-ones has attracted significant interest in recent years due to its effectiveness and capability to produce various molecular libraries. This review presents a thorough summary of the recent advancements […]
This paper uses a one-step synthesis method to prepare NH2-ZIF-8/NCDs porous materials. A series of composite photocatalysts were obtained by adjusting the additional amount of nitrogen-doped carbon quantum dots (NCDs). The structural characteristics of the nanocomposites were characterized using XRD, FTIR, FESEM, TEM, and BET. The photocatalytic activity of NH2-ZIF-8/NCDs nanocomposites was investigated through the […]
Each year an estimated 1.3 billion tons of agricultural waste are produced worldwide, with staple crop residue forming a large bulk of the generated waste. This crop residue from cereal crops like Ragi husk is generally discarded despite being a rich silica source and is a widely used compound with an ever-increasing demand. In the […]
Continued research on pyrazoline derivatives with excellent biological activities has encouraged us to design and synthesize 1,3,5-trisubstituted pyrazoline series introducing NiFe2O4.Cu(OH)2 magnetic nanocomposite as a heterogeneous catalyst by the combination of highly substituted aryl aldehydes, substituted acetophenones, and acetyl hydrazine hydrate under ultrasound irradiation at 50oC. The NiFe2O4.Cu(OH)2 magnetic nanocomposite materials are characterized by […]
In organic chemistry, one of the most important materials are heterocycle compounds. Among different heterocyclic compounds, the N-containing heterocyclic materials are very important owing to their numerous properties, which can be applied in different fields. In this work, we synthesized pyrido[2,3-d:5,6-d′] dipyrimidine derivatives over an efficient and green method. For this aim, we used vitamin […]
This article investigates an efficient and eco-friendly protocol for protecting amines and alcohols as important molecules in organic chemistry, using Fe3O4@MCM-41/Zr@Piperazine as a newly reported magnetic mesoporous nanostructured catalyst. Firstly, the protection of alcohols was developed through their transformation to trimethylsilyl ethers. Then this reagent was applied for the acceleration of the acetylation of […]
Biodiesel production from waste cooking oil (WCO) holds promise as a renewable and sustainable energy source. However, high levels of free fatty acids (FFAs) in WCO require efficient pretreatment before transesterification. Utilizing solar energy for heterogeneous catalytic reactions offers an alternative to thermal-driven processes. TiO2EFBA, synthesized via the wet impregnation method, exhibits distinctive physicochemical properties […]
In this study, the preparation of a new functionalized acidic metal-organic framework nanocatalyst formulated as Zr-MOF-N=CH-C6H4-SO3H has been reported. After characterization using different analysis methods such as FT-IR, XRD, SEM, EDX, TGA, and TEM, the average size of the nanoparticles was found to be between 42.5 and 50.4 nm in diameter. The Nanocatalyst was […]
In this research article, the Schiff base ligand 3-((2-amino-4-nitrophenyl) imino) indolin-2-one (Ln) was synthesized through the reaction between indoline 2, 3-dione and 4-nitrobenzene-1, 2-diamine. The synthesized ligand was then characterized using various analytical techniques, including 1HNMR, UV-Vis, FT-IR, and element analysis C.H.N. The presence of nitrogen (N) and oxygen (O) atoms in the ligand structure […]
A facile chemical mixing approach was used to prepare TiO2/ZnO photocatalystswith different mass ratios. The photodegradation activity was tested against paracetamol in an aqueous phase assisted by low UVC-light intensity (9 W). TiO2/ZnO particles mainly exhibited irregular shapes with uniform distributions and high crystallinity degree, the primary oxidation state in the structure is titanium […]
