We developed a facile and green one-pot synthetic method for substituted 1,3,5-triaryl-1,5-diketones by Claisen-Schmidt condensation following Michael addition reaction of aryl ketones and aryl aldehydes under a transition-metal-free condition. This convenient one-pot synthetic strategy has several advantages, including being transition-metal-free, having no extra additives or reagents, having a broad substrate scope, having a high isolated yield, having a minimum amount of base employment, having a shorter reaction time, use of cheap starting materials, cost-effectiveness, and being environment friendly. Some of the chemical structures of 1,5-diketones were confirmed by X-ray single-crystal diffraction analysis. The application of 1,5-diketones was demonstrated in the preparation of 2,4,6-triaryl pyridine derivatives under a catalyst-free system using ammonium acetate as a nitrogen source.

In this study, different types of Bi2WO6 catalysts were synthesized by a hydrothermal method using Bi(NO3)(3)center dot 5H(2)O and Na2WO4 center dot 2H(2)O as precursors, and various characterization methods, such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy (UV-vis DRS), Brunauer-Emmett-Teller (BET) specific surface area measurements, and photoluminescence (PL) analysis, were used to characterize the morphologies, structures, and valence states of the catalysts. Then, the catalysts were used to catalyze the alpha alkylation reaction of benzyl alcohol and acetophenone to obtain 1,3-diphenyl-1-propenone under visible light irradiation, and the photocatalytic reaction conditions were optimized. To expand the applicable range of alpha alkylation, the influence of different alcohols and different ketone derivatives on the photocatalytic reaction was determined. In addition, the effects of the wavelength and intensity of the light used were also important, and the recyclability of the catalyst and active species (such as superoxide radicals (center dot O-2(-)), holes (h(+)) and electrons (e(-))) produced during the reaction were tested.

Atkamine is a complex marine pyrroloiminoquinone alkaloid that comprises a heptacyclic scaffold bearing five different heterocycles and four contiguous stereocenters, and therefore it is a highly challenging target for synthetic chemists. We herein reported a modular synthetic strategy toward this alkaloid, featuring a formal [5 + 2] annulation and an asymmetric Michael addition. The efficient synthesis of the long-chain aliphatic aldehyde and chiral amino acetal fragments have been achieved. A simplified tetracyclic intermediate bearing the core structure of atkamine has been successfully constructed through the formal [5 + 2] annulation.

The aim of this study was to develop a nondairy fermented product based on mango slurry. Lactobacillus plantarum and Saccharomyces cerevisiae DV10 were used as starter cultures in single and co-cultivations. The microbial populations and metabolites produced during mango slurry fermentation were investigated. At the end of all fermentations, the bacterial populations were higher than 6.0 log CFU/mL. Lactic acid was the main organic acid produced, achieving up to 6.12 g/L after 24 h in co-culture with L. plantarum and S. cerevisiae DV10. Volatile compounds were determined after 24 h of fermentation, the co-cultures of L. plantarum and S. cerevisiae DV10 could decrease terpenes and produce alcohols and esters. The co-cultivations obtained the most total phenolics as well as showed the strongest 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) radical scavenging activity, ferric-reducing antioxidant power (FRAP) and low-density lipoprotein (LDL) oxidation inhibition. Hence, a high-bioactivity probiotic product was successfully obtained via mango slurry fermentation inoculated with a co-culture of L. plantarum and S. cerevisiae DV10.

Dielectric materials play a crucial role in 5G communication technological applications such as printed circuit board (PCB) high-frequency substrate materials. Unfortunately, the fabrication of desirable dielectric performance in organic-inorganic composites is a great challenge because of lack of good interfacial compatibility and uniform dispersion between fillers and polymer. In this work, silicon dioxide (SiO2) was synchronously functionalized by gamma-methacryloxypropyltrimethoxysilane (MPS, s-SiO2) and 1,2-polybutadiene (PB, v-SiO2), which were then used as fillers to fabricate the s-SiO2/polyolefin or v-SiO2/polyolefin laminates. All the v-SiO2/polyolefin laminates exhibited better dielectric, thermal and mechanical properties than those of s-SiO2/polyolefin laminates under the same filler content. Specially, the 50 wt% v-SiO2/polyolefin laminate displays a low dielectric constant (3.42) and loss (3.55 x 10-3) at 10 GHz. Meanwhile, it also shows good stability of dielectric properties in a wide range of high-frequency. This work is conducive to develop laminates with superior dielectric properties and apply to PCB high-frequency substrate field.

The synthesis of aryl phosphonates via nickel and palladium-catalyzed cross-coupling of aryl fluorosulfonates and phosphites is described. The products were obtained in good to excellent yields under mild conditions with broad functional group compatibility, employing either Pd(OAc)(2) and DPEPhos or the readily available NiCl2(dme) and Xantphos as catalytic systems. Noteworthily, the present C(sp(2))-P bond formation method could be applied to the direct conversion of phenols to the corresponding aryl phosphonates in one pot via reaction of phenols with SO2F2 and subsequent palladium-catalyzed cross-coupling.

The development of earth abundant 3d metal-based catalysts continues to be an important goal of chemical research. In particular, the design of base metal complexes for reductive amination to produce primary amines remains as challenging. Here, we report the combination of cobalt and linear-triphos (bis(2-diphenylphosphinoethyl)phenylphosphine) as the molecularly-defined non-noble metal catalyst for the synthesis of linear and branched benzylic, heterocyclic and aliphatic primary amines from carbonyl compounds, gaseous ammonia and hydrogen in good to excellent yields. Noteworthy, this cobalt catalyst exhibits high selectivity and as a result the -NH2 moiety is introduced in functionalized and structurally diverse molecules. An inner-sphere mechanism on the basis of the mono-cationic [triphos-CoH](+) complex as active catalyst is proposed and supported with density functional theory computation on the doublet state potential free energy surface and H-2 metathesis is found as the rate-determining step.

Several diastereoisomeric polyesters bearing vicinal stereogenic centers in the backbone were synthesized to investigate the influence of diastereoisomerism on the properties of polymers. To hamper the free rotation of the C-sp(3)-C-sp(3) single bond between the stereogenic centers, bisphenol monomers containing vicinal CF3 moieties were designed and synthesized, wherein the CF3 group acts not only as a conformational stabilizer but also as a probe to provide information on stereoconfiguration. X-ray single-crystal structure and density functional theory (DFT) calculations indicate that the antimonomer tends to adopt a linear and extended configuration, whereas the most stable conformation for its diastereoisomer is kinked. These geometries resemble those possessed by the E and Z 1,2-disubstituted alkenes. The polymers based on these isomeric monomers display distinct glass transition state temperature (T-g), crystallinities, mesoscopic morphology, and hydrophobicity, which can be attributed to the different polymer chain arrangement in the solid state. These observations support our hypothesis to utilize aliphatic moieties bearing vicinal stereogenic centers to mimic the geometry of the E and Z olefinic units, which serves as a new strategy to finely tune the polymer
