New Pyrazole-Based Ligands: Synthesis, Characterization, and Catalytic Activity of Their Copper Complexes

The purpose of this study is to demonstrate the synthesis of pyrazole-based ligands and to evaluate their catalytic properties in the oxidation reaction of catechol to o-quinone. The ligands were prepared via the condensation of (3,5-dimethyl-1H pyrazol-1-yl)methanol A with the appropriate primary amine. Four pyrazole-based ligands were successfully synthesized and characterized. These ligands provide one pyrazole sp(2)-nitrogen, one pyridine sp(2)-nitrogen, and one amine sp(3)-nitrogen, which were capable of coordinating to the metal. For evaluating the catalytic activity, the experiments were tested by varying the type of solvent, metal ion, anion in the metal salt, and ratios of ligands and metal salts. Excellent catalytic activities for the oxidation of catechol to o-quinone were obtained. The copper (II)-based complexes showed better reactions rates than those based on other metals (e.g., nickel, tin, and barium), which was due to the fact that the active catalytic site of the catecholase enzyme has two active sites from the existence of copper (II) ions. The composition ratios of ligands and metal salts as well as the type of anion in the metal salt bring impacts to the formation of complexes. We found also that the type of solvent contributes to the interaction and dilution of reactants in the solvent. This study demonstrated that the present ligands can be used as a model for further developments in catalytic processes relating to catecholase activity.

A Cu doped TiO2 catalyst mediated Catalytic Thermo Liquefaction (CTL) of polyolefinic plastic waste into hydrocarbon oil

Plastic waste has been identified as a potent feedstock for liquefaction to produce hydrocarbon liquid oil (HC-Oil) by employing Catalytic Thermo Liquefaction (CTL). The resulting process for liquefaction of plastic was termed as Poly-Urja process and produced hydrocarbon oil was termed as HC-Oil. The CTL explores copper doped TiO2 (Cu@TiO2) catalyst as a selective, robust, non-toxic, inexpensive and promising material for liquefaction of polyolefinic plastic waste with minimum char and gas formation. The use of simple, non-expensive and noncomplex co-precipitation method has provided a series of Cu@TiO2 catalysts with variable composition of the metal. Of the synthesized catalysts, Cu@TiO2 with 5% metal loading gave maximum conversion and yield of HCOil in laboratory batch reactor. The physicochemical and surface morphological properties of the catalyst were studied by using ATR-FTIR, XRD, SEM-EDX, BET and ICP-MS. Process intensification study was conducted to obtain maximum conversion and yield. The intensified CTL process gave >85% conversion and >80% yield of HC-Oil at less stringent conditions. HC-Oil is a carbon rich substrate comprises of 75-85% carbon, 5-15% hydrogen, 5-10% other elements and have a calorific value of similar to 42 MJ/kg thus it can be used for multiple applications of energy, fuels and chemicals etc. Physicochemical characterization of HC-Oil showed the presence of long and short; straight and branched chains of hydrocarbons (C-8-C-28). Moreover, CTL can convert any combination of plastic waste into HC-Oil with minimum carbon loss and >80% yield. Thus, the CTL process for polyolefinic waste provides an efficient, sustainable and environmentally friendly alternative to convert plastic waste into energy.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 16606-55-6, you can contact me at any time and look forward to more communication. SDS of cas: 16606-55-6.

Transition Metal-Promoted Reactions in Aqueous Media and Biological Settings

During the last decade, there has been a tremendous interest for developing non-natural biocompatible transformations in biologically relevant media. Among the different encountered strategies, the use of transition metal complexes offers unique possibilities due to their high transformative power. However, translating the potential of metal catalysts to biological settings, including living cells or small-animal models such as mice or zebrafish, poses numerous challenges associated to their biocompatibility, and their stability and reactivity in crowded aqueous environments. Herein, we describe the most relevant advances in this direction, with a particular emphasis on the systems’ structure, their mode of action and the mechanistic bases of each transformation. Thus, the key challenges from an organometallic perspective might be more easily identified.

Pd/Cu-Catalyzed Defluorinative Carbonylative Coupling of Aryl Iodides and gem-Difluoroalkenes: Efficient Synthesis of alpha-Fluorochalcones

An unprecedented and challenging defluorinative carbonylation was achieved. Enabled by a Pd/Cu cooperative catalyst system, the first example of defluorinative carbonylative coupling has been established. With gem-difluoroalkenes and aryl iodides as the substrates, this methodology offers flexible and facile access to privileged alpha-fluorochalcones under mild reaction conditions in moderate-to-excellent yields. Mechanistic studies indicated transmetalation between palladium and copper intermediates as a crucial step of the catalytic cycle.

Electroreduction of CO2 to formate with excellent selectivity and stability on nano-dendrite Bi film electrode

Electroreduction of CO2 into value-added fuels has been considered as a promising technology to mitigate the CO2-invoked greenhouse effect. However, the poorer selectivity and lower stability of electrocatalysts still impede its development. In this work, we prepared a nano-dendrite Bi film electrode by simple one-step electrodeposition method. The Bi (1200) (deposition time of 1200s) exhibited a superior catalytic activity in a wide potential towards CO2-to-formate conversion and acquired the maximum faradaic efficiency (FEformate) of 97.5 % at -1.5 V vs Ag/AgCl. More encouragingly, it showed an excellent stability as the FEformate maintained similar to 90 % over 108 h of electrolysis which outperformed most of the reported Bi-based electrodes. The notable performance was mainly attributed to the thorn-like structure which afforded massive active sites. Meantime, Bi-O structure on oxide-derived Bi was beneficial for CO2 adsorption and activation with accelerated interfacial charge transfer process. Moreover, the well-preserved electrode morphology and Bi-O component enabled its longer stable service life. This result implied Bi film electrode would be a promising candidate for efficient CO2 electroreduction.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 16606-55-6 help many people in the next few years. Recommanded Product: (R)-4-Methyl-1,3-dioxolan-2-one.

Copper-promoted heterogeneous Fenton-like oxidation of Rhodamine B over Fe3O4 magnetic nanocatalysts at mild conditions

Rhodamine B (RhB) is used in various industries and its effluent must be effectively treated because of its harmful and carcinogenic nature. In this work, ionothermally synthesized Cu-doped Fe3O4 magnetic nanoparticles (Cu-Fe3O4 MNPs) were found to be a highly efficient heterogeneous Fenton-like catalyst for complete decolorization of the RhB solution with H2O2 at pH similar to 7 and 25 degrees C. The effects of the catalyst loading, initial concentrations of RhB and H2O2, co-existing natural organic matter and inorganic salts, reaction temperature, and radical scavengers on the catalytic performance of Cu-Fe3O4 were investigated. Monte-Carlo simulations revealed that copper dopants facilitated the activation of H2O2 via adopting a terminal end-on adsorption mode and increased collision frequency by bringing the RhB molecules closer to H2O2 and the magnetite surface. These theoretical calculations provide new insight into the promotional effect of copper dopants in magnetite at molecular level.

Copper ferrite anchored on hexagonal boron nitride as peroxymonosulfate activator for ciprofloxacin removal

In this study, CuFe2O4 anchored on h-BN (CuFeBN) at various %w/w ratios was prepared via a hydrothermal method and characterized. The CuFeBN catalyst consists of irregular microparticle-like morphology with uniform CuFe2O4 distribution and magnetic property. It was employed as peroxymonosulfate (PMS) activator for ciprofloxacin (CIP) removal. The results indicated that CuFeBN with CuFe2O4:h-BN w/w ratio of 1:2 (or CuFeBN-12) performed the best with CIP removal efficiency exceeding 91% in 60 min (apparent rate constant, kapp = 0.0901 min(-1)). Higher CuFe2O4:h-BN w/w ratio resulted in increased CuFe2O4 agglomeration. Additionally, increasing the CuFeBN-12 loading and initial pH leads to gradual increase in kapp due to the increased catalytic sites and catalyst-to-PMS interaction, respectively. The redox cycling between Cu(II)/Cu(I) and Fe(III)/Fe(II) resulted in the formation of SO4-, acting as the main radical for CIP degradation and mineralization. Overall, the CuFeBN-12 shows remarkable potential as PMS activator for treating antibiotics in water. (c) 2020 Elsevier B.V. All rights reserved.

Cashew nutshell liquid catalyzed green chemistry approach for synthesis of a Schiff base and its divalent metal complexes: molecular docking and DNA reactivity

Cashew Nut Shell Liquid (CNSL) anacardic acid was used, for the first time, as a green and natural effective catalyst for the synthesis of a quinoline based amino acid Schiff base ligand from the condensation of 2-hydroxyquinoline-3-carbaldehyde with l-tryptophan via solvent-free simple physical grinding technique. The use of the nontoxic CNSL natural catalyst has many benefits over toxic reagents and the desired product was obtained in high yield in a short reaction time. The procedure employed is simple and does not involve column chromatography. Moreover, a series of metal(II) complexes (metal = iron(II), cobalt(II), nickel(II), and copper(II)) supported by the synthesized new quinoline based amino acid Schiff base ligand (L) has been designed and the compositions of the metal(II) complexes were examined by various analytical techniques. The findings imply that the 2-hydroxyquinoline-3-carbaldehyde amino acid Schiff base (L) serves as a dibasic tridentate ONO ligand and synchronizes with the metal(II) in octahedral geometry in accordance with the general formula [M(LH)(2)]. Molecular docking study of the metal(II) complexes with B-DNA dodecamer has revealed good binding energy. The conductivity parameters in DMSO suggest the existence of nonelectrolyte species. The interaction of these metal complexes with CT-DNA has shown strong binding via an intercalative mode with a different pattern of DNA binding, while UV-visible photo-induced molecular cleavage analysis against plasmid DNA using agarose gel electrophoresis has revealed that the metal complexes exhibit photo induced nuclease activity.

Electroactive Metal Complexes Covalently Attached to Conductive PEDOT Films: A Spectroelectrochemical Study

The successful covalent attachment, via copper(I)-catalyzed azide alkyne cycloaddition (CuAAC), of alkyne-function-alized nickel(II) and copper(II) macrocyclic complexes onto azide (N-3)-functionalized poly(3,4-ethylenedioxythiophene) (PEDOT) films on ITO-coated glass electrodes is reported. To investigate the surface attachment of the selected metal complexes, which are analogues of the cobalt-based complex previously reported to be a molecular catalyst for hydrogen evolution, first, three different PEDOT films were formed by electropolymerization of pure PEDOT or pure N-3-PEDOT, and last, 1:2N(3)-PEDOT:PEDOT were formed by co-polymerizing a 1:4 mixture of N-3 -EDOT:EDOT monomers. The successful surface immobilization of the complexes on the latter two azide-functionalized films, by CuAAC, was confirmed by X-ray photoelectron spectroscopy (XPS) and electrochemistry as well as by UV-vis-NIR and resonance Raman spectroelectrochemistry. The ratio between the N-3 groups, and hence, the number of surface-attached metal complexes after CuAAC functionalization, in pristine N-3-PEDOT versus 1:2N(3)-PEDOT:PEDOT is expected to be 3:1 and seen to be 2.86:1 with a calculated surface coverage of 3.28 +/- 1.04 and 1.15 +/- 0.09 nmol/cm(2), respectively. The conversion, to the metal complex attached films, was lower for the N-3-PEDOT films (Ni 74%, Cu 76%) than for the copolymer 1:2N(3)-PEDOT:PEDOT films (Ni 83%, Cu 91%) due to the former being more sterically congested. The Raman and UV-vis-NIR results were simulated using density functional theory (DFT) and time-dependent DFT (TD-DFT), respectively, and showed good agreement with the experimental data. Importantly, the spectroelectrochemical behavior of both anchored metal complexes is analogous to that of the free metal complexes in solution. This proves that PEDOT films are promising conducting scaffolds for the covalent immobilization of metal complexes, as the existing electrochromic features of the complexes are preserved on immobilization, which is important for applications in electrocatalytic proton and carbon dioxide reduction, optoelectronics, and sensing.
