A series of bis(phosphinite) (POCOP) pincer ligated nickel complexes, [2,6-(tBu(2)PO)(2)C6H3]NiX (X = SH, 1; SCH2Ph, 2; SPh, 3; NCS, 4; N-3, 5), were used to catalyse the hydrosilylation of aldehydes. It was found that both complexes 1 and 2 are active in catalysing the hydrosilylation of aldehydes with phenylsilane and complex 1 is comparatively more active. The expected alcohols were isolated in good to excellent yields after basic hydrolysis of the resultant hydrosilylation products. However, no reaction was observed when complex 3 or 4 or 5 was used as the catalyst. The results are consistent with complexes 1 and 2 serving as catalyst precursors, which generate the corresponding nickel hydride complex [2,6-(tBu(2)PO)(2)C6H3]NiH in situ, and the nickel hydride complex is the active species that catalyses this hydrosilylation process. The in situ generation of the nickel hydride species was supported by both experimental results and DFT calculation.

A new series of 3-(quinazol-2-yl)-quinolines was synthesized by SNAr reaction from easily prepared 4-chloro-2-(2-chloroquinolin-3-yl)quinazolines and a range of phenols and thiophenol as nucleophiles. The AlCl3-mediated CC bond formation was also successfully exploited to introduce aryl and hereroaryl substituents on one or both heterocyclic units. These procedures afford efficient syntheses of polysubstituted 3-(quinazol-2-yl)-quinolines in few steps and high yields. Some of these polysubstituted 3-(quinazol-2-yl)-quinolines inhibit the human 20S proteasome. (C) 2020 Elsevier Ltd. All rights reserved.

The push-pull electronic and steric effect of copper porphyrin catalysts on the cross-dehydrogenative coupling (CDC) reaction between the hydroxyl group of phenol substrates and C(sp(3))-H bond have been investigated. Results showed that copper porphyrin bearing electron-withdrawing, bulky steric hindrance or heteroatom of pyridyl groups could increase the catalytic activity in the reaction. 5,10,15,20-(tetrakis(4-pyridyl)porphyrin)copper (CuTPyP) was found the best among all tested catalysts. Phenol substrates bearing various functional groups afforded moderate to excellent yields (99%). Significantly, as compared to other tested copper porphyrins, CuTPyP not only exhibited remarkable higher activity but also could shorten the reaction time from 12 to 6 h.

Optimal performance of multi-step enzymatic one-pot cascades requires a facile balance between enzymatic activity and stability of multiple enzymes under the employed reaction conditions. We here describe the optimization of an exemplary two-step one-pot recycling cascade utilizing the thiamine diphosphate (ThDP)-dependent benzaldehyde lyase from Pseudomonas fluorescens (PfBAL) and the alcohol dehydrogenase from Ralstonia sp. (RADH) for the production of the vicinal 1,2-diol (1R,2R)-1-phenylpropane-1,2-diol (PPD) using both enzymes as catalytically active inclusion bodies (CatIBs). PfBAL is hereby used to convert benzaldehyde and acetalydehyde to (R)-2-hydroxy-1-phenylpropanone (HPP), which is subsequently converted to PPD. For recycling of the nicotinamide cofactor of the RADH, benzyl alcohol is employed as co-substrate, which is oxidized by RADH to benzaldehyde, establishing a recycling cascade. In particular the application of the RADH, required for both the reduction of HPP and the oxidation of benzyl alcohol in the recycling cascade is challenging, since the enzyme shows deviating pH optima for reduction (pH 6-10) and oxidation (pH 10.5), while both enzymes show only low stability at pH>8. This inherent stability problem hampers the application of soluble enzymes and was here successfully addressed by employing CatIBs of PfBAL and RADH, either as single, independently mixed CatIBs, or as co-immobilizates (Co-CatIBs). Single CatIBs, as well as the Co-CatIBs showed improved stability compared to the soluble, purified enzymes. After optimization of the reaction pH, the RADH/PfBAL ratio and the co-solvent content, we could demonstrate that almost full conversion (>90%) was possible with CatIBs, while under the same conditions the soluble enzymes yielded at most >50% conversion. Our study thus provides convincing evidence that (Co-)CatIB-immobilizates can be used efficiently for the realization of cascade reactions, i. e. under conditions where enzyme stability is a limiting issue.

Background: In continuation of our work, new diazenyl chalcones scaffolds (C-18 to C-27) were efficiently synthesized from substituted acetophenone azo dyes (A-E) by base catalyzed Claisen-Schmidt condensation with different substituted aromatic/heteroaromatic aldehydes. Methodology: The synthesized chalcones were assessed for their in vitro antimicrobial potential towards several pathogenic microbial strains by tube dilution method and further evaluated for antioxidant potential by DPPH assay. These derivatives were also assessed for the cytotoxicity towards the human lung cancer cell line (A549) and normal cell line (HEK) by MTT assay. The most active antimicrobial compounds were docked using Schrodinger v18.1 software with the various potential bacterial receptors to explore the mechanism of interaction. Results: The derivative C-22 exhibited high antibacterial activity with very low MIC (1.95-3.90 mu g ml(-1)) and MBC (3.90-7.81 mu g ml(-1)) values. The derivatives C-23, C-24 and C-27 have demonstrated good antioxidant potential (IC50 = 7-18 mu g ml(-1)) correlated to the ascorbic acid (IC50 = 4.45 mu g ml(-1)). The derivative C-25 had shown comparable cytotoxicity to camptothecin against A549 cell line. The docking studies predicted the bacterial dihydrofolate reductase (PDB ID: 3SRW) and bacterial DNA gyrase (PDB ID: 4ZVI) as the possible targets for most of the active antimicrobial compounds. These derivatives affirmed their safety by presenting less cytotoxicity towards HEK cells. Further the ADME prediction by qikprop module of the Schrodinger proved that these compounds exhibited drug-like attributes. Conclusion: Hence, these compounds have shown their potential as lead for future expansion of novel antimicrobial and cytotoxic drugs.

In this study, Co3O4 nanocatalysts were constructed in environmentally appropriate conditions using controlled, effective, and facile microwave method. The final nanostructures were characterized by SEM, XRD, and TEM analyses. The products had a small size distribution, homogeneous morphology, and crystallographic structures associated with the formation of Co3O4 nanostructures. Moreover, EDS mapping analysis confirmed the existence of Co and O elements in the final structure, and the magnetic properties of the samples were investigated by VSM. The application of this nanostructure in a catalytic process was further examined, and the results suggested that it could be used as a novel candidate for the synthesis of arylidene barbituric and Meldrum(,)s acid through Knoevenagel condensation of aldehydes by barbituric and Meldrum(,)s acid in aqueous media. The high yield of these nanocatalysts would be justified by the nature of the nanostructure as well as the experimental procedure developed in this study, which affected the physicochemical features of the products.

Name: 4-Methoxybenzaldehyde. I found the field of Chemistry; Physics very interesting. Saw the article Verification of corrosion inhibition of Mild steel by some 4-Aminoantipyrine-based Schiff bases – Impact of adsorbate substituent and cross-conjugation published in 2021.0, Reprint Addresses Kar, PK (corresponding author), Veer Surendra Sai Univ Technol, Dept Chem, Burla 768018, India.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde.

Corrosion inhibition of mild steel (MS) by a series of 4-aminoantipyrine-based Schiff base has been studied in 1 N HCl aqueous medium adopting electrochemical method at different concentration (10(-2)-10(-5) M) and temperature (303-333 K). All of the inhibitors were found to be dominated by cathodic/anodic in nature (mixed type). Electrochemical impedence and polarization studies were in agreement with each other. The surface morphology (smoothness and roughness) was characterized by SEM, which indicates the formation of protective layer on the MS surface. The substituents on the Schiff bases influence their corrosion inhibition properties. Schiff bases having -OCH3, -OH and -NMe2 substituents exhibit more inhibition tendency as compared to other substituents. The role of cross conjugation in electron donating as well as accepting properties by heteroatom (N, O) and pi-electrons in corrosion inhibition was clearly observed from DFT calculations. Monolayer formation on the MS surface has been confirmed from the Langmuir isotherm fitting. Thermodynamic modeling has been done to understand the nature of adsorption. The values of Delta G (>-30 kJ/mol/K) indicate the existence of both physical and chemical interactions between the Schiff base molecules and metal surface. (C) 2021 Elsevier B.V.

The photocatalytic behavior of the graphene oxide (GO) modified Fe(III)/peroxymonosulfate (Fe/PMS) system for bisphenol A (BPA) degradation was investigated. With the addition of GO, a dramatic enhancement of BPA degradation was obtained at pH 3.0 under visible light irradiation. According to ESR analysis and quenching tests, both SO4 center dot- and center dot OH are responsible for BPA degradation. The characterization analysis demonstrates that Fe(III) can chelate with the oxygenic functional groups on the surface of GO forming a stable GO-Fe(III) complex. The detections of different kinds of Fe species reveal that Fe(III) can be reduced to Fe(II) by GO via intramolecular electron transfer in the GO-Fe(III) complex, and visible light could enhance this process. The Fe(III)/Fe(II) cycle not only occurs on the surface of GO, but also in aqueous solution via homogeneous reactions. In addition, the degradation pathway of BPA was proposed based on the identification of the intermediates using GC-MS and LC-MS techniques. (C) 2020 Elsevier Inc. All rights reserved.
