An efficient, environmental friendly and substrate controlled method of synthesis of 2-substituted benzimidazole derivatives 3 and 1,2-disubstituted benzimidazole derivatives 4 with high selectivity has been achieved from the reaction of o-phenylenediamine 1 and aldehydes 2 in the presence of water extract of onion and selecting suitable reaction medium. This method is widely applicable for variety of aldehydes such as aromatic/aliphatic/heterocyclic aldehydes and 1,2-diamines to afford 2-substituted benzimidazole derivatives 3 and 1,2-disubstituted benzimidazole derivatives 4 in good to excellent yields (up to 96%). The developed method of water extract of onion catalysis produced 2-substituted benzimidazoles 3 from aromatic aldehydes having electron-withdrawing groups, whereas aromatic aldehydes bearing electron donating groups selectively furnished 1,2-disubstituted benzimidazole 4 derivatives. The process described here has several advantages of cheap, low energy consumption, commercially available starting materials, operational simplicity and nontoxic catalyst. The use of water extract of onion makes this present methodology green and giving a useful contribution to the existing methods available for the preparation of benzimidazole derivatives. In addition, Hammett correlation of substituent constant (sigma) vs percentage (%) yield has been established.

Bimetallic transition metal phosphide catalysts are promising materials for low-temperature, liquid-phase hydrogenation reactions. This work explores the chemoselective hydrogenation ability of RuMoP using various functionalized aromatic hydrocarbons to provide insight into how the functional groups compete for reduction on the surface of RuMoP. Using molecular hydrogen as the reductant, high selectivity (similar to 99%) to reduction of the substituent is achieved for the hydrogenation of electron withdrawing functionalities such as nitrobenzene, benzaldehyde, and benzophenone with RuMoP to yield aniline, benzyl alcohol, and diphenylmethanol, respectively. In contrast, aromatics with electron donating groups such as phenol, anisole, and toluene, show high ring hydrogenation selectivity (similar to 99%) to form cyclohexanol, methoxycyclohexane, and methyl cyclohexane, respectively, although the reaction proceeded slowly with RuMoP. Pyridine adsorption was studied via diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), which provided evidence of surface electron deficient sites (i.e., Lewis acids) that are responsible for targeting the electron-rich portion of the substrate. Additional DRIFTS experiments were performed using nitrobenzene, anisole, and a mixture of the two. From these experiments, features associated with -NO2 adsorption in nitrobenzene and ring adsorption in anisole were observed, which correlated well with the observed reaction results. Finally, a solvent study provided evidence for the competitive adsorption of isopropanol and the pi-electrons from the aromatic ring of phenol with the former being more favorable on RuMoP surface.

Two new sulfonated (SDA) and carboxylated (CDA) aromatic diamine-diol monomers were synthesized and applied to prepare thin-film composite (TFC) nanofiltration (NF) membranes with improved antifouling and performance properties. The interfacial polymerization method was used to make sulfonated and carboxylated TFC-NF membranes with reaction of trimesoyl chloride (TMC) in the organic phase with amine and hydroxyl agents in the aqueous phase. Herein, for the first time, a comparison between carboxylated and sulfonated TFC was carried out. Moreover, the probability of synergetic effect between these two synthetic monomers (CDA and SDA) and piperazine monomer was studied (the sulfonated monomer and piperazine showed a synergetic effect). The outcomes of flux recovery ratio (FRR), flux and contact angle showed that in the presence of newly synthesized monomers, membrane hydrophilicity considerably improved. The salt retention sequence for all membranes was Na2SO4 NaCl > CaCl2, which means all membranes had a negative charge. Among the five prepared TFC membranes (SDA, CDA, PIP, SDA/PIP, and CDA/PIP), the SDA/PIP showed the best salt rejection (97% Na2SO4) with flux (50 Lm(-2)h(-1)) and 91% FRR, at operating pressure of 10 bars. Although the SDA showed the highest permeability (62 Lm(-2) h(-1)) and FRR of 92%, it presented the lowest Na2SO4 rejection. The results indicated that mixing carboxylated monomers with PIP caused deterioration in properties, while mixing sulfonated monomer with PIP enhanced the performances of the related TFC. Better permeability of the membrane made by newly synthesized monomers is ascribed to the existence of strong hydrophilic sulfonic acid, carboxylic acid and terminal hydroxyls, and amine groups at polyamide top layer producing enhanced membrane antifouling properties.

A series of novel N’-(2-thiouracil-5-oyl)hydrazones were designed and chemically synthesized using an active substructure combination method. The synthesized compounds were structurally characterized on the basis of elemental (%) analyses, IR, MS, H-1 NMR, and C-13 NMR spectra. All the prepared compounds were evaluated in vitro against MCF-7 human breast cell line using MTT assay. The anticancer results showed that compounds 3j, 4a, 3c, 3b , and 3h exhibit the most prominent effect against breast cancer cell line with IC50 values of 3.40, 3.50, 3.60, 3.70, and 3.80 mu g/ml, respectively using doxorubicin as a control drug. Moreover, molecular docking studies were also performed in order to identify the binding mode mechanism of these compounds with prospective target, thymidylate synthase (PDB:1JU6). On the other hand, the antibacterial activities of all prepared compounds were screened in vitro against three bacterial strains, namely, Escherichia coli, and Pseudomonas aeruginosa as Gram negative bacteria and Staphylococcus aureus as a Gram positive bacterium using agar well diffusion method. The antibacterial activity results revealed that most of the compounds under test were inactive however, among all the tested compounds, only 3g and 4a , in a concentration of 50 mu g/ml showed a high antibacterial activity against the three used bacterial strained. It is worthy to note that the potency of 3g against Escherichia coli was comparable to that of the reference drug, while compound 2 exhibited significant activity against Pseudomonas aeruginosa only and compound 3j displayed low activity against Staphylococcus aureus. The structure-antibacterial activity relationship analysis can be modulated by the presence of aromatic or heteroaromatic moiety containing more lipophilic character significantly contributed to antibacterial activity. In addition, the drug-likeness properties have predicted for the target compounds. (C) 2021 Published by Elsevier B.V.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Incorporation of mesopores and active sites into metal-organic framework (MOF) materials to uncover new efficient catalysts is a highly desirable but challenging task. We report the first example of a mesoporous MOF obtained by templated electrosynthesis using an ionic liquid as both electrolyte and template. The mesoporous Cu(II)-MOF MFM-100 has been synthesised in 100 seconds at room temperature, and this material incorporates crystal defects with uncoupled Cu(II) centres as evidenced by confocal fluorescence microscopy and electron paramagnetic resonance spectroscopy. MFM-100 prepared in this way shows exceptional catalytic activity for the aerobic oxidation of alcohols to produce aldehydes in near quantitative yield and selectivity under mild conditions, as well as having excellent stability and reusability over repeated cycles. The catalyst-substrate binding interactions have been probed by inelastic neutron scattering. This study offers a simple strategy to create mesopores and active sites simultaneously via electrochemical formation of crystal defects to promote efficient catalysis using MOFs.

We report Pd-catalyzed ortho-C-H methoxylation and chlorination of benzaldehydes by employing monodentate transient directing groups (TDGs) as an alternative strategy to bidentate TDGs. More importantly, a single crystal of benzaldehyde imine ortho-cyclopalladium intermediate was successfully obtained, and its structure was unambiguously determined by X-ray diffraction, which clearly showed that it was a binuclear palladium species bridged by a pyridone ligand. The utility of this approach was further demonstrated through the synthesis of key intermediates of natural products and drugs.

Uracil compounds participate in a wide range of biological activities; however, reports on their synthesis using heterogeneous catalysts are scarce. In this work, the multicomponent synthesis of uracil derivatives assisted by layered double hydroxides (LDH) was studied under green chemistry conditions. The incorporation of Ni2+ or Co2+ was successfully performed by co-precipitation method. The yields to uracil derivatives are associated with the presence of weak basic sites and a better interaction of the reagents when the reaction is carried out in solvent-free conditions. The reaction pathway involves the formation of an enone between benzaldehyde and ethyl cyanoacetate, and subsequent reaction with urea, which is assisted by the presence of a basic catalyst. The scope of this synthesis is illustrated with nine examples.
