In this research, a novel, biodegradable and environmentally friendly catalyst composed of nickel nanoparticles supported on DNA was prepared and fully characterized by Fourier transform infrared spectroscopy, high resolution transmission electron microscopy, energy-dispersive X-ray analysis, X-ray photoelectron spectroscopy, UV-vis spectroscopy, inductively coupled plasma optical emission spectroscopy, and elemental analysis. The catalyst exhibited remarkable catalytic activity and chemoselectivity for the reduction of various substituted nitroarenes with sodium borohydride (NaBH4) as the source of inexpensive hydride in water at room temperature. High turnover frequency and selectivity were observed for the reduction of all tested substrates. Interestingly, the catalyst could be recovered conveniently for multiple recycling reactions with sustained activity. Furthermore, nearly no nickel species was leached out from the catalyst during the course of reaction, proving the true heterogeneity in the present catalytic protocol.Graphical AbstractThe reduction of various nitroaromatic compounds into their corresponding amines is achieved by DNA supported nickel nanoparticles with the sodium borohydride as the reducing agent in water at room temperature.

A series of robust metallo-aerogels are readily fabricated by pyrolysis of xerogels derived from chitosan-metal (M = Fe, Co, Ni) hydrogels. Owing to the strong coordination between metal ions and the functional groups (NH2 and OH) of chitosan, metallo-aerogels consisting of encapsulated metal-nanoparticles (MNPs) by graphite shells were obtained, as supported by various characterizations including high-resolution transmission electron microscope (HR-TEM), X-ray diffraction (XRD), and Raman. The resulting metallo-aerogels could be functioned as highly stable, efficient and selective nanocatalysts towards the hydrogenation of nitroarenes to amines at low catalyst loading (1.2 mol.%-2.4 mol.%). Remarkably, the metallo-aerogels could be reused for more than 30 runs without obvious loss of activity and selectivity. These distinguished performances were attributed to the graphitic shells formed during the pyrolysis, which hampered the possible aggregation of MNPs, prevented metal leaching and increased their stability.

A Lewis base supported terminal uranium phosphinidene, [eta(5)-1,3-(Me3C)(2)C5H3]2U(= P-2,4,6-(Bu3C6H2)-Bu-t)(OPMe3) (5), is isolated from the reaction of the uranium methyl chloride [eta(5)- 1,3-(Me3C)(2)C5H3](2)U(Cl) Me (4) with 2, 4, 6-(Me3C)(3)C6H2PHK in toluene in the presence of Me3PO. Moreover, the reactivity of uranium phospinidene 5 toward a series of small molecules was comprehensively explored. While no reactivity of 5 with internal alkynes is observed attributed to steric hindrance, it readily reacts in good yields with various small molecules including isothiocyanates, aldehydes, imines, diazenes, carbodiimides, nitriles, isonitriles, and organic azides, yielding uranium sulfidos, oxidos, metallaheterocycles, and imido complexes.

A novel metal-free catalytic one-pot approach has been developed for the esterification of aralkyl ketones with alcohols under open-air atmospheric conditions. The inexpensive iodide/oxone reagent system allowed the cascade C(sp(3))-H bond oxygenation, selective C-C bond cleavage and esterification through the both radical and ionic pathways in a stepwise manner in one-pot. This mild, convenient and economically viable catalytic method tolerates the various functional groups to provide the corresponding alkyl benzoates in up to 98% yields with up to 99% selectivity. The efficiency and feasibility of scale-up of the present catalytic system was demonstrated with gram scale experiments (up to 10 gram scale).

We demonstrate a method to boost the photocatalysis of titania by constructing a core-shell structure. The crucial technique is to capsulate the titania nanoparticles by a sheath of nitrogen-doped carbon (TiO2@N-AC) with a thickness at 3.5-7.5 nm, which creates an exceptional effect to accelerate the catalytic hydrogenation of substituted nitroarenes with isopropanol as the hydrogen source under ultraviolet or visible-light irradiation. In the catalytic hydrogenation of various nitroarenes with substituted groups of -Cl, -F, -C-C, -C-O, and -C=N, TiO2@N-AC exhibits high conversions and selectivities to the corresponding functionalized anilines, even outperforming the catalysts containing noble metals. Mechanism study demonstrates that the TiO2@N-AC catalyst benefits the selective adsorption of the nitro group rather than other substituted groups, which efficiently avoids the undesirable side reactions. Importantly, the catalyst is stable and exhibits constant performances in the continuous recycling tests.

Hydrofunctionalization, the direct addition of an X-H (e.g., X=O, N) bond across an alkene, is a desirable strategy to make heterocycles that are important structural components of naturally occurring molecules. Described here is the design and discovery of donor-acceptor-type platinum catalysts that are highly effective in both hydroalkoxylation and hydroamination of unactivated alkenes over a broad range of substrates under mild conditions. A number of alkene substitution patterns are accommodated, including tri-substituted, 1,1-disubstituted, (E)-disubstituted, (Z)-disubstituted and even mono-substituted double bonds. Detailed mechanistic investigations suggest a plausible pathway that includes an unexpected dissociation/re-association of the electron-deficient ligand to form an alkene-bound donor-acceptor-type intermediate. These mechanistic studies help understand the origins of the high reactivity exhibited by the catalytic system, and provide a foundation for the rational design of chiral catalysts towards asymmetric hydrofunctionalization reactions. The direct addition of an O-H (hydroalkoxylation) or an N-H (hydroamination) bond across an alkene is a useful strategy to access biologically relevant heterocycles. Here, the authors report donor-acceptor-type platinum catalysts that are effective for both hydroalkoxylation and hydroamination of unactivated alkenes, with broad substrate scope and use of mild conditions.

Selective oxidation of aromatic alkanes by C-H activation is one of the key reactions in organic synthesis and the chemical industry. Activation of C-H bonds to obtain high-value added products under mild conditions by using sustainable carbocatalysts is of particular interest. Herein, we report a sustainable, green and template-free strategy towards the fabrication of N-doped and N/S codoped carbon nanosheets by metal-free carbonization of bioprecursors guanine and guanine sulfate. The formation of thin and N/S codoped carbon nanosheets was induced by multiple interactions of the nucleobases. Benefiting from the unique textural structure of the as-synthesized carbons, including ultrathin thickness, optimal porosity, and rich structural defects, and the synergistic coupling effect of multiple dopants, the carbon nanosheets show a high catalytic performance with 85% ethylbenzene conversion and 98% selectivity to acetophenone at 80 degrees C after 4 h reaction, which outperforms other equivalent benchmarks (e.g. 8.5 times higher conversion and 3.2 times higher selectivity than those of oxidized carbon nanotubes). Density functional theory simulations indicate that the oxidation of ethylbenzene is catalyzed by the synergistic effect of p-N/S and g-N/S catalysts via an OH radical mechanism. This N/S codoped strategy provides guidance for the design of carbon-based catalysts for the selective oxidation of other alkanes.

Four new piperine derivatives, PC1-PC4, were synthesized, and their structures were fully characterized by infrared (IR) and H-1 and C-13 nuclear magnetic resonance (NMR) spectroscopies. Quantum chemical calculations were performed using density functional theory (DFT) with the B3LYP-D3/6-31G(d,p) and 6-311+G(2d,p) basis sets. Electronic properties, such as the energy gap between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) and some global chemical reactivity descriptors, were evaluated to study the reactivity and stability of the compounds. H-1 and C-13 NMR chemical shifts were calculated by using the gauge-invariant atomic orbital (GIAO) method and compared with experimental values. In addition, the compounds were evaluated in an antifungal study against Candida, Trichophyton and Microsporum strains, and only PC4 showed 70% inhibition in ten tested strains, with a minimum inhibitory concentration (MIC) ranging from 1.23-2.46 mu mol mL(-1) and a minimum fungicide concentration (MFC) ranging from 9.84-19.68 mu mol mL(-1), and presented a fungistatic effect.

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.

Porous organic polymers (POPS) containing nitrogenous substituents have potential practical applications as heterogeneous catalysts based upon controlled porous structure and surface-anchored noble metal nanoparticles (NMNPs). In this work we prepared a POP material from piperazine and cyanuric chloride starting materials (PC-POP). The PC-POP material contains numerous triazinyl moieties, thus rendering the pores hydrophobic. Subsequently, by means of a novel reverse double-solvent approach (RDSA), microdroplets of Pd(AcO)(2)/CH2Cl2 were introduced into the hydrophobic pores of PC-POP in an aqueous environment; Pd(II) was rapidly reduced by NaBH4 to form ultra-fine Pd NPs and confined within the pores of PC-POP at high dispersity. The extensive porosity and dispersity of the Pd NPs made the active sites readily accessible, and led to efficient mass transfer. Thus, Pd@PC-POP exhibits superior catalytic performance in catalytic reduction of various nitroarenes. Furthermore, Pd@PC-POP has excellent recyclability, without significant loss of activity nor leaching of Pd active sites during 10 successive reaction cycles. This work points to a practical and cost-effective approach to preparation of POP materials, and also for confining ultra-fine NMNPs in POPs for use as catalysts. (C) 2018 Elsevier Inc.
