First, we note in this paper that alpha-Hydroxyphosphonate acid ester was synthesized before; we confirmed it by a new method and its various properties are discussed experimentally and theoretically. The structure of Diethyl [hydroxy(4-methoxyphenyl) methyl] phosphonate (DH4MPMP) resolved by SXRD is compared to the optimized geometry, the FT-IR, NMR, UV-Vis spectroscopies results were compared and discussed experimentally and theoretically. The Hirshfeld surface analyses were employed to determine qualitative and quantitative intermolecular interactions present in the solid state and through, the supramolecular 3D-network was discussed. The UV-Vis spectrum exhibit a strong absorption in middle UV domain and an optical transmittance in the visible one. To be close from the experimental results, all DFT calculations based on B3LYP/6-31G (d,p) were detailed on monomer and dimer models. The DFT calculation of the second-order nonlinear optical properties is based on the first static hyperpolarizability (beta), the results show that the material might have nonlinear optical properties. The calculated frontier molecular orbitals and their energies were calculated. The research was extended to the calculations of the molecular electrostatic potential map; it shows negative potential areas localized around oxygen atoms as well as the positive localized around the hydrogen atoms. Finally, the thermodynamic functions (entropy, heat capacity and enthalpy) were determined from spectroscopic data by statistical methods in the range 100-1000 K and the experimental thermal decomposition behavior was analyzed by TGA.

The palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd-2(dba)(3)/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(eta(3)-C3H5)Cl](2)/XPhos is more efficient. The regiochemical outcome shows that the nucleophilic substitution occurs only on the benzylic position of the eta(3)-(benzofuryl)methyl complex. The high to excellent yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2-substituted benzo[b]furans.

In this project, nano-MnO2@zeolite-Y (NMOZ) was successfully prepared via hydrothermal technique and its structure was confirmed using FT-IR, XRD, FE-SEM, EDX and BET analyses. MnO2 nanoparticles stabilized on zeolite-NaY were used as nanocatalyst for efficient solventless preparation of 3,4-disubstituted isoxazole-5(4H)-one scaffolds via one-pot three-component reaction of ethyl acetoacetate, hydroxylamine hydrochloride, and aromatic aldehydes at 100 degrees C. One of the advantages of this new method is the non-use of a metal oxidant such as KMnO4 (greener method) and the stabilization of MnO2 to the zeolite-Y surface via ion bonding. This causes the MnO2 not be leached from the zeolite during the processes of nanocatalyst recycling in organic reactions. This simple approach also has promising features as like as safe, inexpensive and recyclable nanocatalyst, solvent-free reaction, short reaction times, high to excellent yields, and easy isolation of the products.

Before biobased fuels can replace fossil fuels, several key issues must be addressed. Bio-oils derived through pyrolysis of lignocellulosic material have high acidity and viscosity, and poor energy density and stability. To address these issues, this paper examines the individual and combined behavior of lignocellulosic feedstock components to shed light on the potential to generate preferential biofuel properties through biomass mixing. Dry lignocellulosic biomass is mostly composed of cell wall polysaccharides (cellulose, hemicellulose, lignin), which vary widely in type and concentration across biomasses. This heterogeneity leads to increased unpredictability in biobased fuel formation during pyrolysis. Using derivative thermogravimetric (DTG) analysis, gas chromatography-mass spectroscopy, and residual gas analysis, this work explores the synergistic interactions of lignocellulosic biomass components during pyrolysis to manipulate bio-oil and gas product composition based on desired compound classes. Cellulose, xylose, xylan, and lignin were blended at different ratios to determine the extent of synergistic effects during pyrolysis. For each mixture, an ‘expected’ outcome was developed by summing the individual behavior (e.g. mass loss rate, H-2 gas evolution, etc.) of the individual components based on mass fraction present. Mixtures containing lignin and/or xylan yield peak DTG mass loss rates at lower temperatures than predicted with corresponding reductions in biochar yield suggesting synergistic interactions that promote devolatilization. By itself, lignin produces large amounts of hydrogen gas, and when mixed with other biomasses promotes dehydrogenation. Lignin increases CO2 formation, resulting in lower oxygen concentrations in the bio-oil and biochar. While suppressing bio-oil generation, the presence of lignin – even at low concentrations – increases the number of phenol compounds produced, while decreasing the yield of furans. The synergistic interactions between different polysaccharides could be exploited depending on the desired biorefinery products – allowing for targeted selection of lignocellulosic biomass mixes to fine-tune resulting fuels.

Electro-synthesis through a one-pot three-component condensation of corresponding aldehydes, Meldrum’s acid, and 2-(nitromethylene)imidazolidine resulted in a series of novel tetrahydroimidazo[1,2-a]pyridine-5(1H)-one derivatives containing an electronegative pharmacophore (=CNO2). The process was carried out in propanol medium with sodium bromide presented as electrolyte, inside an undivided cell with good to excellent yields. As a powerful entry into fused polycyclic structures related to bioactive heterocycles, this green protocol shows great potential. [GRAPHICS] .

Fenclorim is a commercial herbicide safener with fungicidal activity used for chloroacetanilide herbicides, which might be suitable as a lead compound for screening novel fungicides. However, little has been reported so far on the structure-activity relationship of fungicidal activities of fenclorim or its analogues. Here, a series of 4-chloro-6-substituted phenoxy-2-phenylpyrimidine derivatives was synthesized by a substructure splicing route using fenclorim as a lead compound. The structures of synthesized derivatives were characterized by H-1 NMR, C-13 NMR, and HRMS. Their fungicidal and herbicide safening activities were then evaluated. The results revealed that compound 11 had the best fungicidal activity against Sclerotinia sclerotiorum and Thanatephorus cucumeris, which was better than that of the control pyrimethanil. Moreover, compounds 3, 5, and 25 exhibited excellent safening activities against fresh weight, plant height, and root length, respectively. Such activities were significantly improved when compared to fenclorim. In summary, these findings look promising for the preparation of new fungicides and herbicide safeners based on the structure of fenclorim.

Unsaturated vegetable oils and their corresponding fatty acid derivatives constitute interesting renewable platforms for the preparation of heterocycles, notably through the formation of oxygenated intermediates. In this work, fatty imidazoles were prepared from the corresponding 1,2-diketones through Debus-Radziszewski reaction. The reaction was optimized under microwave irradiation using a 1,2-diketone derived from methyl oleate and ammonium acetate as a nitrogen source. Using benzaldehyde as a model substrate, the reaction occurs at 180 degrees C for 5 min and the desired imidazole was formed in 96 % GC yield. A range of aldehydes was tested under the optimized conditions and the corresponding imidazoles were obtained in 33-99 % isolated yields (20 examples).

This paper reports the synthesis and characterization of Cu nanoparticle loaded, surfactant free metallovesicles (CuNPs@vesicles) as nanoreactors to produce benzimidazoles via cascade reaction. The vesicles exhibited uniform size distribution, spherical morphology, excellent stability and efficient Cu loading. This strategy is unique for the fact that, environmental contaminants like nitroaniline have been utilized as precursor and converted into fine chemicals of commercial significance via non-toxic intermediates. CuNPs@vesicles reduces 2-nitroaniline to o-phenylenediamine which further acts as precursor for benzimidazole synthesis. Thus the reaction occurs via two step cascade pathway comprising reduction and C-N cross coupling reactions in water. The preliminary studies suggest encouraging results for performing dehydrogenative coupling under relatively mild conditions using CuNPs@vesicles as a catalyst. All the products are obtained in good to excellent yield with facile catalyst regeneration and recyclability upto 5 cascading cycles. (C) 2021 Elsevier B.V. All rights reserved.
