We report here on the preparation of an efficient, easily recoverable and reusable Fe3O4 magnetic nanoparticle-supported Cu(II)-β-cyclodextrin complex catalyst for synthesis symmetrical biaryls 1,2,3-triazoles from arylboronic acids. The presented was characterized by TEM, XRD, VSM, TGA, FT-IR spectrometer. By using catalyst, we have developed efficient protocol homocoupling aryl boronic acids biaryls. is also active in via a one-pot reaction acid with sodium azide water followed click...
Abstract We report here the transition‐metal‐catalyzed chemoselective cross‐coupling of arylbroronic acids in high yields without using ligand or base. have developed an efficient copper‐catalyzed protocol for homocoupling and arylboronic acids. The is also suitable aliphatic primary amines with Aminophenols bearing alcoholic substituent on chain were coupled acids, products obtained C–N coupling selectivity. An effective catalyst was Cu 2 –β‐cyclodextrin, which readily available...
We report here the one-pot synthesis of 1,2,3-triazoles arylboronic acids in water. An efficient method has been developed for via a reaction an acid with sodium azide presence Cu2–β-CD (CD = Cyclodextrin) as nanocatalyst water followed by click cyclization alkyne at room temperature air without any additives. This is simple, rapid, and high yielding.
ABSTRACT Hydrogels containing TiO 2 nanoparticles (NPs) have photocatalytic properties and degrade pollutants under light. In this study, a polyacrylamide (PAAm) hydrogel was synthesized with P25 NPs as the initiator, acrylamide monomer, N,N ′‐methylene bisacrylamide crosslinker in aqueous media sunlight. Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, transmission microscopy were applied to characterize /PAAm hydrogel. The effects of...
A simple, efficient, and new method has been developed for the preparation of thiophosphates from benzenethiols. The involves copper(I) iodide catalyzed coupling thiols with <i>H</i>-phosphonates in presence triethylamine. reaction proceeds effectively to afford corresponding moderate good yields via an aerobic dehydrogenative This is easy, rapid, good-yielding synthesis
Alumina-supported phosphorus pentoxide was found to be an efficient reagent for the synthesis of 1,5-benzodiazepine derivatives from phenylenediamine and ketones in solvent-free condition under microwave irradiation.This method is easy, rapid, high-yielding reaction 1, 5-bezodiazepines.Heterocyclic compounds hold a special place among pharmaceutically important natural synthetic materials.The remarkable ability heterocyclic nuclei serve both as biomimetics active pharmacophores has largely...
Mononuclear complexes [Pt(ppy)(S∧S)] (1a, S∧S = O,O′-di(cyclohexyl)dithiophosphate (ctp); 2a, O,O′-di(butyl)dithiophosphate (btp)) and [Pt(bzq)(S∧S)] (1b, ctp; 2b, btp) have been prepared by the reaction of precursor [Pt(C∧N)Cl(dmso)], C∧N deprotonated form 2-phenylpyrdine (ppy) 7,8-benzoquinoline (bzq), potassium salt ligands. All were characterized NMR spectroscopy, structure 2b was further identified single crystal X-ray determination. Although are not luminescent in solution at ambient...
Fe3O4 magnetic nanoparticles-supported EDTA–copper(II) complex (Fe3O4-EDTA–Cu(II)) has been prepared and characterized by TEM, SEM, XRD, VSM, TGA, FT-IR spectrometers. The catalyst was applied for the C–N coupling of arylboronic acids with amines preparation N-aryl compounds. Recovery tests confirm that can be easily recovered reused up to eight times without significant loss its catalytic activity.
Aim: To induce a safe death to MCF-7 human breast cancer cell line through gene therapy based on iC9 suicide gene. Materials & methods: apoptosis line, was transfected using pyridine-functionalized multi-walled carbon nanotubes. Then, enhance chemotherapy, performed alongside. Results: The results show that the cells were efficiently eliminated in high percentage by this approach. Furthermore, itself/in combination with chemotherapeutic drugs managed pass cycle arrests. Conclusion: We...
Coumarin fused heterocyclic compounds are important materials with wide applications in biological and drug design. We report here a novel condensation-cyclization reaction of 4-chloro-3-formylcoumarin amidoximes. The gave conjunction hybrid compound coumarin pyrimidinones.
