Herein, a dual nickel/ruthenium strategy is developed for photoinduced decarboxylative cross-coupling between alpha,beta-unsaturated carboxylic acids and cycloketone oxime esters. The reaction mechanism is distinct from previous photoinduced decarboxylation of alpha,beta-unsaturated carboxylic acids. This reaction might proceed through a nickelacyclopropane intermediate. The C(sp(2))-C(sp(3)) bond constructed by the aforementioned reaction provides an efficient approach to obtaining various cyanoalkyl alkenes, which are synthetically valuable organic skeletons in organic and medicinal chemistry, under mild reaction conditions. The protocol tolerates many critical functional groups and provides a route for the modification of complex organic molecules.

The solvent free oxidation of benzyl alcohol to Benzaldehyde using bimetallic alloy nanoparticles supported over magnesia is a benign and improved frontier in catalysis. Benzaldehyde is an important industrial feed stock of immense significance in plastic, fine and chemical industries. In this study 1% Au:Pd NPs was synthesized using sol immobilization method over different magnesia (MgO) supports. The composite nanoalloys were characterized using Nitrogen adsorption BET, X- ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The efficacy of Pd:Au/MgO, as a basic solid catalyst, has been tested for benzyl alcohol oxidation. The synthesized composite catalyst Pd:Au/MgO-4 showed high initial activity for freshly prepared catalysts with remarkable activity. This activity declined rapidly with number of runs, which could result from sintering of the support, agglomeration and leaching of active phase. Furthermore, MgO-3 exhibits good stability after 2nd runs, while MgO-5 and MgO-2 revealed marked increasing in activity after the 2nd runs due surface modification and exposure of active sites during reaction.

Presently, developing efficient and stable structured heterogenous catalysts with fabulous advantages of excellent ability for heat/mass transfer, facile recovery and separation, and superior stability is of great importance in terms of economic production of chemicals. Here, structured Cu-based film catalysts with novel surface superstructure composed of large quantities of interlaced and nearly vertically grown nanosheets for aqueousphase hydrogenation of furfural toward the production of furfuryl alcohol (FOL) and cyclopentanone (CPO) were successfully fabricated from structured Cu-Zn-Al layered double hydroxide (CuZnAl-LDH) film precursors. As-fabricated structured Cu-based film catalyst possessing a Cu/(Zn + Cu) molar ratio of 4:5 exhibited a superior catalytic performance in the above reaction to other Zn-free and Zn-rich Cu-based film catalysts, as well as pristine CuZnAl-LDH-derived powdered one, due to the synergistic effect between highly dispersive Cu species and favorable surface acidic sites originating from LDH-derived Zn-Al mixed metal oxide (ZnAl-MMO), as well as the presence of abundant Cu-MMO interface within surface nanosheets, being responsible for the enhanced adsorption and activation of reactant and reaction intermediates. Furthermore, due to strong interactions between Cu species and MMO matrix within nanosheets and between surface nanosheets and anodic aluminum oxide/aluminum substrate, the present structured catalyst showed high structural stability and reusability.

Isomerization-based strategies to enable the stereodivergent construction of complex polyenes from geometrically defined alkene linchpins remain conspicuously underdeveloped. Mitigating the thermodynamic constraints inherent to isomerization is further frustrated by the considerations of atom efficiency in idealized low-molecular weight precursors. In this work, we report a general ambiphilic C-3 scaffold that can be isomerized and bidirectionally extended. Predicated on highly efficient triplet energy transfer, the selective isomerization of beta-borylacrylates is contingent on the participation of the boron p orbital in the substrate chromophore. Rotation of the C(sp(2))-B bond by 90 degrees in the product renders re-excitation inefficient and endows directionality. This subtle stereoelectronic gating mechanism enables the stereocontrolled syntheses of well-defined retinoic acid derivatives.

A novel method was used to prepare a magnetic phenylene-based periodic mesoporous organosilica nanocomposite with yolk-shell structure (Fe3O4@YSPMO). The Fe3O4@YSPMO nanomaterial was prepared by using easily accessible pluronic-P123 and cetyltrimethylammonium bromide (CTAB) surfactants under basic conditions. This material was employed for effective immobilization of potassium perruthenate to prepare an Fe3O4@YSPMO@Ru nanocatalyst for the aerobic oxidation of alcohols. The physiochemical properties of the designed Fe3O4@YSPMO@Ru nanocomposite were studied using PXRD, FT-IR, TGA, SEM, TEM, ICP, VSM and XPS analyses. Fe3O4@YSPMO@Ru was effectively employed as a highly recoverable nanocatalyst in the selective aerobic oxidation of alcohols.

Cocoa fermentation is an essential step for chocolate production whereby flavor potential is generated and bitterness and astringency are moderated. To facilitate fermentation research in laboratories geographically distant from cocoa-growing regions, and to simplify and control the fermentation system, a laboratory fermentation model system was developed. The model system consisted of dried unfermented beans, artificial pulp medium, and laboratory incubator to control temperature and aeration. The model system developed in this study showed a succession of key microorganisms including Saccharomyces cerevisiae, Lactobacillus plantarum, Lactobacillus fermentum, Acetobacter pasteurianus, and Acetobacter tropicalis. The pH of cocoa beans decreased to an acceptable final pH (4.8). Sugars were well consumed and acetic acid and ethanol were produced during fermentation. Desirable volatile compounds including phenylethyl alcohol, acetoin, 2-phenylethyl acetate, and 3-methylbutyl acetate increased in the cocoa beans during fermentation. In addition, the concentration of polyphenols decreased with fermentation. These results lead to the conclusion that the model system developed in this study was able to simulate the microbial and chemical changes occurring in in situ cocoa fermentation. This laboratory-scale model system will enable systematic examination of the effects of process parameters on fermented bean quality.

HPLC of Formula: C8H8O2. I found the field of Chemistry very interesting.

Aurone-derived azadienes are well-known four-atom synthons for direct [4 + n] cycloadditions owing to their s-cis conformation as well as the thermodynamically favored aromatization nature of these processes. However, distinct from this common reactivity, herein we report an unusual formal migrative annulation with siloxy alkynes initiated by [2 + 2] cycloaddition. Unexpectedly, this process generates benzofuran-fused nitrogen heterocyclic products with formal substituent migration. This observation is rationalized by less common [2 + 2] cycloaddition followed by 4 pi and 6 pi electrocyclic events. DFT calculations provided support to the proposed mechanism.

An efficient Cu(II)-catalyzed radical addition of maleimides has been achieved. The identified copper catalyst enables the formation of oxime radicals (N-O-center dot) by cleaving the O-H bond in ketoximes, followed by the radical addition to N-substituted maleimides. The oxime radicals (N-O-center dot) were detected and confirmed by EPR spectroscopy and variable-temperature H-1 NMR. The simple one-pot reaction realizes the facile preparation of a variety of oxime ether adduct products in moderate to good yields. (C) 2019 Elsevier Ltd. All rights reserved.

Wheat bran, which contains a large amount of cellulose, is used as a raw material to produce soy sauce, but it is hard to degrade during fermentation. Steam explosion (SE) is efficient in hydrolyzing the cellulose for enhancing enzymatic digestion and solvent accessibility. In this study, we applied a SE at a sufficiently high pressure to damage the integrity of the wheat bran structure and modify it to assume a layered form. We found that cellulose, hemicellulose, and lignin structures were collapsed by SE pretreatment, which was indicated by their changes in Fourier transform infrared spectroscopy (FTIR). The amounts of cellulose, hemicellulose, and lignin decreased by 5.8%, 21.4%, and 43.4%, respectively, under 1.5 MPa, resulting in the significant reduction of sugar and amino acid nitrogen. The co-reaction of nonenzymatic browning after SE pretreatment resulted in an intense increase in flavor (overall feeling), as determined by electronic nose analysis and sensory evaluation. In conclusion, SE pretreatment under 1.0 MPa was proven to be the most optimal state for the production of aroma compounds (volatile compounds), which are essential for soy sauce production.
