Ni3Sn2 alloy catalysts supported on various metal oxides (TiO2, Al2O3, ZrO2, SnO2, and CeO2) were successfully prepared by simple hydrothermal method and then applied to the hydrogenation of 4-nitrostyrene under H-2 3.0 MPa at 423 K. All the supported catalysts hydrogenated the nitro group more preferentially than the olefin group from the initial reaction stages, showing 100% chemoselectivities towards the desired 4-aminostyrene. This may be attributed to sigma-interaction between the oxygen lone pairs in the nitro group and Sn atoms in Ni3Sn2 alloy. By prolonging the reaction times, the 4-aminostyrene yields increased and finally reached the maximum yields. Among the catalysts, Ni3Sn2/TiO2 alloy catalyst showed the highest catalytic activity with remarkably high chemoselectivity towards 4-aminostyrene. The conversion and chemoselectivity were 100% and 79%, respectively, at a reaction time of only 2.5 h. From the physical and chemical characterization of the supported catalysts, it was clear that the catalytic activity was correlated with H-2 uptake. The application of the best catalyst for the hydrogenation of a wide variety of substituted nitroarenes resulted in the chemoselective formation of the corresponding aminoarenes.

Structural and third-order nonlinear optical (NLO) properties of two D-pi-A-pi-A [(2E)-3-(3-chlorophenyl)-1-(3-nitrophenyl)prop-2-en-1-one (3C3NC) and (2E)-3-(4-fluorophenyl)-1-(4-nitrophe nyl)prop-2-en-1-one (FNC)] and one D-pi-A-pi-D [(2E)-1-(9-anthryl)-3-(4-fluorophenyl) prop-2-en-1-one (FANC)] type chalcone derivatives were investigated experimentally as well as theoretically. All the three chalcones are centrosymmetric (CS) and crystallized in P2(1)/c space group. In crystal packing, all compounds exhibit CeH center dot center dot center dot O hydrogen bonds and pi center dot center dot center dot pi interactions. From UV-Vis-NIR absorption spectra, the cut-off wavelength and optical band gaps of the chalcones were evaluated. The thermal stability and the melting point of the chalcones were determined from the TGA/DTA techniques. The ultrafast third-order NLO properties of the three chalcones in solution (0.01 M) were evaluated by Z-scan technique using femtosecond (fs) pulses from Ti: Sapphire laser (similar to 150 fs, 80 MHz, 800 nm). Third-order nonlinear absorption (NLA) coefficient (beta similar to 10(-9) cmW(-1)), nonlinear refraction (NLR) index (n(2)similar to 10(-14) cm(2)W(-1)), susceptibility (chi((3)) similar to 10(-12) esu) and molecular hyperpolarizability (gamma(h) similar to 10(-31) esu) were unambiguously determined. The chalcones satisfy the condition to observe reverse saturable absorption (RSA) mechanism (sigma(ex) > sigma(g)). Further, the larger values of sigma(ex)/sigma(g) (similar to 2-3) indicate that the chalcones would exhibit remarkable optical limiting property. The estimated optical limiting (OL) threshold values are in the order of mu J/cm(2). Further, all the chalcones have satisfied the one-photon and two-photon figures of merit conditions (W > 1 and T < 1) for the optical switching applications. In addition to experimental findings, the optimized geometry, HOMO-LUMO energy gap, NLO parameters such as electronic dipole moment, polarizability, first and second hyperpolarizabilities of all the three chalcones were determined theoretically (DFT) for different wavelength at B3LYP/6-311 thorn G (d,p) basic set. The experimentally determined second-order susceptibilities (Z-scan technique) are reasonably in agreement with the computational values (TD-DFT). The MEP surface revealed that the 3C3NC, FNC and FANC molecules have some potential sites for electrophilic and nucleophilic attack. The experimental and computational NLO data clearly suggest that the nonlinearity of chalcone molecules greatly depends on the electron donor and acceptor strengths of the substituents. Further, all the chalcones are potential materials for optical limiting and optical switching applications. (C) 2020 Elsevier B.V. All rights reserved.

We report an easily recoverable and reusable versatile magnetic catalyst (Fe3O4@CS_AgNi, where CS = chitosan) for organic reduction reactions. The catalytic system is prepared by dispersing AgNi bimetallic nanoparticles on the magnetite core-shell (Fe3O4@CS). The as-synthesized catalyst has been characterized by spectroscopic techniques, such as IR, UV-vis, and X-ray photoelectron spectroscopy (XPS), and analytical tools, such as thermogravimetric analysis, powder X-ray diffraction, Brunauer-Emmett-Teller adsorption, FEG-scanning electron microscopy, high-resolution transmission electron microscopy (HR-TEM), inductively coupled plasma-atomic emission spectroscopy, and magnetic measurements. HR-TEM studies indicate the core-shell structure of Fe3O4@CS and confirm the presence of AgNi nanoparticles on the surface of Fe3O4@CS spheres. IR spectral and XPS studies lend evidence for the occurrence of a strong chemical interaction between the amino groups of CS and AgNi nanoparticles. The nano-catalyst Fe3O4@CS_AgNi rapidly reduces p-nitrophenol to p-aminophenol using NaBH4 as the reductant within a few minutes under ambient conditions (as monitored by UV-visible spectroscopy). The utility of this catalytic system has also been extended to the reduction of other nitroarenes. A strong interaction between Fe3O4@CS and AgNi nanoparticles impedes the leaching of AgNi nanoparticles from the core-shell support, leading to excellent reusability of the catalyst.

One hot debate between catalytic activities of sulfonated reduced graphene oxide (RGO-SO3H), as the 2D heterogeneous carbon-based catalyst, and sulfonated multi-walled carbon nanotubes (MWCNTs-SO3H), as the 1D heterogeneous carbon-based catalyst, was investigated in the synthesis of 1,3,5-triarylbenzenes under different conditions. This comparison study revealed that the 2D catalytic system was more efficient relative to the 1D catalyst in terms of yields of the target products, turnover frequency of the catalyst (TOF), and the reusability. The reasons of this observation such as specific surface area, confinement spaces in 1D and 2D carbon-based catalysts, solvent accessible surface area, surface active sites, and the availability of supported functional groups on carbon nanostructures will discuss. Moreover, the application of synthesized compounds as a substrate was checked in carbon-carbon bond formation. Also, one of the synthesized compounds was produced using three approaches under metal and non-metal conditions. Notably, the recyclability of the two catalytic systems was checked.

The objective of this work is to apply yellow mustard seeds in the enzymatic reduction (biocatalysis) of acetophenone and its derivatives, providing a new biocatalyst for this type of reduction. The reaction parameters were optimized from acetophenone, resulting in 1-phenylethanol, with 68.5% conversion yield and 53% enantiomeric excess (e.e.), analyzed by GC and HPLC, respectively. Reactions to acetophenone and its derivatives were conducted in aqueous medium using buffers pH 6.0 and pH 6.5 in the presence of PVP. A polymer that can act as a protector preventing oxidation of peroxidase enzymes. The results for the derivatives presented low yields (4-18%: substances 5, 7 and 8), moderate (28-40%: substances 3, 4 and 6) and optimum (81%: substance 2) yields, with enantiomeric excesses varying from good to excellent results. Meta-substituted derivatives showed inversion of configuration in the presence of PVP. The biocatalyst was also tested in reactions with other carbonyl compounds, presenting moderate results. In this way, this work offers a new perspective of the application of PVP in biocatalysis reactions and a new biocatalyst for future applications.

Dementia is a cognitive disorder mostly associated with Alzheimer’s disease (AD) in addition to being seen in many other diseases of the central nervous system (CNS). The limited number of drugs is not sufficient to provide adequate improvement to increase the quality of life of patients suffering from this symptom; therefore, all treatment options should be evaluated in detail. In this study, new molecules, [2-(4-(2/3/4-substituted phenyl)piperazin-1-yl)-4-phenylthiazol-5-yl][3/4-substituted phenyl]methanone derivatives (1-44), were obtained and analyzed in terms of their anticholinesterase activities. Kinetic mode and molecular interactions were also evaluated. An enzyme inhibition study was undertaken on acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) using the Ellman method. Maestro program was used in molecular modeling studies. Forty-four compounds were evaluated on AChE and BChE enzymes at 10(-3) and 10(-4) concentrations. The inhibition concentrations were calculated as 0.268 mu M to 2.104 mu M for six compounds (4, 5, 16, 27, 37, and 38) on AChE. Compound 5 including the 4-methoxy substituent (IC50: 0.268 mu M) and compound 38 containing the 4-methoxy and 3-methyl substituents (IC50: 0.286 mu M) showed the highest AChE inhibitory activity. They were further examined in terms of hydrogen bonding with Arg296 and Ar-Ar interaction with Trp286. The activity of compound 5 was also assessed in mixed-type kinetic mode.
