In this work, the new trinuclear manganese catalyst defined as Fe3O4@NFC@NNSM-Mn(iii) was successfully manufactured and fully characterized by different techniques, including FT-IR, XRD, TEM, SEM, EDX, VSM, and ICP analysis. There have been reports of the use of magnetic catalysts for the synthesis of xanthine derivatives. The critical potential interest in the present method include short reaction time, high yields, recyclability of the catalyst, easy workup, and the ability to sustain a variety of functional groups, which give economical as well as ecological rewards. Also, the synthesized catalyst was used as a recyclable trinuclear catalyst in alcohol oxidation reactions at 40 degrees C. The magnetic catalyst activity of Fe3O4@NFC@NNSM-Mn(iii) could be attributed to the synergistic effects of the catalyst Fe3O4@NFC@NNS-Mn(iii) with melamine. Employing a sustainable and safe low temperature, using an eco-friendly solvent, no need to use any additive, and long-term stability and magnetic recyclability of the catalyst for at least six successive runs are the advantages of the current protocol towards green chemistry. This protocol is a benign, environmentally friendly method for heterocycle synthesis.

The one-pot synthesis of a series of sulfonium salts containing transferable diazomethyl groups is described, and the structure of these compounds is elucidated by X-ray crystallography. Under photochemical conditions, reaction of these salts with N,N-dialkyl hydrazones affords 1-(dialkylamino)-1,2,3-triazoles via diazomethyl radical addition to the azomethine carbon followed by intramolecular ring closure. The straightforward transformation of the structures thus obtained into mesoionic carbene-metal complexes is also reported and the donor properties of these new ligands characterized.

The infection of Xanthomonas oryzae pv. Oryzae (Xoo), Ralstonia solanacearum (Rs), and Xanthomonas axonopodis pv. Citri (Xac) has become a major problem in agricultural production. In this study, a series of novel chalcone derivatives containing thioether triazoles were designed and synthesized. The structures of the novel compounds were systematically characterized via H-1-NMR, C-13-NMR, and HRMS. Moreover, the antibacterial activity results showed that E-10, E-11, E-15, and E-16 have adequate antibacterial activities against Xoo, Rs, and Xac. Among the different compounds, E-15 exhibited remarkable inhibitory effect against Xac with an EC50 of 9.1 mu g.mL(-1), which was better than that of commercial agent bismerthiazol (54.9 mu g.mL(-1)). In addition, the possible antibacterial mechanism of the target compound E-15 against Xac was studied via scanning electron microscopy (SEM).

The multicomponent synthesis of 1-amidoalkyl naphthols and polyhydroquinolines has been developed as an atom-economic procedure catalyzed by a deep eutectic solvent ([CholineCl][ZnCl2](3)). The reactions proceed smoothly at low temperatures for a short reaction time without the use of toxic and volatile organic solvents. Deep eutectic solvents are capable of not only allowing multicomponent reactions to proceed in high yield but also controlling the selectivity towards desired products. The mechanistic insight was examined by HRMS (ESI) to propose a plausible mechanism. Furthermore, [CholineCl][ZnCl2](3) can be recycled in up to three consecutive cycles with an insignificant loss of catalytic activity under the optimized conditions.

1,2,3-Triazole contained conjugated porous polymers (CPPs) have recently emerged as a new class of efficient photocatalysts. To gain more insight into the excellent photocatalytic activity of this kind of CPPs, herein, we report the design and preparation of a series of 1,2,3-triazole-based CPPs via oxidative coupling polymerization to study their photocatalytic performance. These CPPs have donor-acceptor properties and 1,2,3-triazole serves as an electron acceptor. The resulting CPPs with thiophene, carbazole and diphenylamine as electron donor units, respectively, have distinct porosities and optoelectronic properties, and showed effective photocatalytic performance towards oxidative hydroxylation of arylboric acids and alkylation of vinylarenes with diethyl bromomalonate or bromoacetonitrile. The thiophene contained CPP was a more efficient photocatalyst for the catalytic reactions, which can be attributed to its smaller optical band gap and greater charge separation effi-ciency. Furthermore, PTPT has shown reliable recyclability with no significant loss in its catalytic activity.

Ten new pyridine linked various substituted thiazole hybrids through (hydrazonomethyl) phenoxy-acetamide spacer were synthesized. The synthetic strategy was based on the reaction of the precursor 2-(4-((2-carbamothioylhydrazono)methyl)phenoxy)-N-(pyridin-2-yl)acetamide (3) with various alpha-halogenated carbonyl compounds (namely; phenacyl bromides, ethyl bromoacetate, diethyl bromomalonate and 3-chloropentane-2,4-dione). Moreover, the cytotoxicity properties of the synthesized compounds have been studied against liver carcinoma (HepG2), laryngeal carcinoma (Hep-2), prostate cancer (PC3), breast cancer (MCF-7) and normal fibroblast cells (W138). The pyridine-thiazole compounds 7 and 10 revealed promising anticancer activity against MCF-7 and HepG2 cell lines with IC50 values in the range 5.36-8.76 mu M compared to the activity of 5-fluorouracil.

Catalysis is the second largest application for V after its use as an additive to improve steel production. Molecular complexes of vanadium(V) are particularly useful and efficient catalysts for oxidation processes; however, their ability to catalyze reductive transformations has yet to be fully explored. Here we report the first examples of polar organic functionality reduction mediated by V. Open-shell V-III complexes that feature a pi-radical monoanionic 2,2′:6′,2 ”-terpyridine ligand (Rtpy(center dot))(-) functionalized at the 4′-position (R = (CH3)(3)SiCH2, C6H5) catalyze mild and chemoselective hydroboration and hydrosilylation of functionalized ketones, aldehydes, imines, esters, and carboxamides with turnover numbers (TONs) of up to similar to 1000 and turnover frequencies (TOFs) of up to similar to 500 h(-1).Computational evaluation of the precatalyst synthesis and activation has revealed underappreciated complexity associated with the redox-active tpy chelate.

A new strategy is presented for enhancing the catalytic activity of cross-linked chitosan beads. More precisely, chitosan beads were cross linked with glutaraldehyde and then, vinyl functionalized. In the next step, the vinyl-functionalized beads were polymerized with the as-prepared 1-vinyl-3-butylimidazolium bromide to furnish polyionic liquid on beads. The resultant compositewas subsequently utilized as a metal-free catalyst for catalyzing some classic organic transformations, including Knoevenagel condensation reaction and syntheses of tetrahydrobenzo[b]pyrans and pyrano[2,3-d]pyrimidines in aqueous media under mild reaction conditions. It was found that the novel composite could efficiently promote all of the examined reactions to afford the corresponding products in high yields. Moreover, the catalyst exhibited high recyclability for all reactions. The comparative studies also approved that the activity of the composite was superior compared to cross-linked bead and polyionic liquid. (C) 2021 Elsevier B.V. All rights reserved.

One-pot oxidative cascade catalysis plays a central role in the synthesis of key pharmaceutical and industrial molecules. Although ionic liquids are one of the most promising solvents and reaction media, the breakthrough of their catalysis in aerobic oxidation is very challenging due to the difficulty in the direct activation of molecular oxygen. Herein, a family of novel thermally regulated molybdate-based ionic liquids (Mo-ILs) has been designed and developed for the first time toward molecular oxygen activation for highly efficient tandem oxidative catalysis. Three diverse one-pot oxidative cascade processes for the syntheses of various flavones, imines, and benzyl benzoates were achieved with good to excellent yields using the Mo-IL [Bmim](2)[MoO4] as a catalyst under air conditions. The results of spectroscopic investigations and quantum-chemical calculations further demonstrated that a thermally regulated proton migration between the cation [Bmim] and anion [MoO4] was the key to forming N-heterocyclic carbene and thereby to effortlessly promoting the generation of O-2(-) active species from molecular oxygen, which results in excellent catalytic performance in these three aerobic tandem oxidations. Our work extends the application area of ILs as the sole catalyst to one-pot aerobic oxidative cascade catalysis, which could have pronounced implications in future work.

Imine reduction is one of the most frequently used transformations in organic synthesis. In this work, we developed novel partially carbonized chitin/Ru microspheres (PCRuMs) featuring a tightly assembled nanofiber structure as a highly efficient catalyst of imine hydroboration for the first time. The hydroboration using HBpin as the hydrogen source proceeds under mild conditions (room temperature and a green solvent). The PCRuM catalyst exhibited excellent catalytic activity, chemoselectivity, and recyclability for the hydroboration of imines. Various functional groups including NO2, C N, CO2Me, and C=C bonds were tolerated. Moreover, the PCRuM catalyst can be reused for up to eight runs without noticeably losing activity.
