Lignin presents as a renewable aromatic resource for value-added chemical production. However, it remains challenging to cleavage C-C bonds in lignin under ambient conditions. Electrochemical oxidation as a renewable energy technology presents an attractive alternative to traditional processes. Herein, we report an efficient electrocatalytic strategy for C-alpha-C-beta bond cleavage of the beta-O-4 linkage in lignin model compounds at room temperature with platinum as the anode and tert-butyl hydroperoxides (t-BuOOH in water, 70% aq soln) as the oxidants, exhibiting high yields for the aromatic aldehydes and phenols. This electrocatalytic strategy is demonstrated to be highly selective for the transformation of a broad selection of lignin model dimers, polymeric compound, and even real lignin into the desired aromatic aldehydes. Mechanistic studies indicate that the reaction may proceed via a C-beta radical process involving a peroxide intermediate. This work opens up opportunities in electrocatalysis to selectively break C-alpha-C-beta bonds and transform lignin to valuable chemicals under ambient conditions by using renewable electricity.

This work is generally focused on the synthesis of an efficient, reusable and novel heterogeneous Al2O3/CuI/PANI nanocatalyst, which has been well synthesized by a simple self-assembly approach where aniline is oxidized into PANI and aniline in the presence of KI also acts as a reductant. The nanocatalyst was well characterized by XRD, FTIR, SEM, EDX, TEM, BET and XPS techniques. In this study, the fabricated material was employed for the catalytic one-pot synthesis of 2-substituted benzimidazoles via condensation between o-phenylenediamine and aldehydes in ethanol as a green solvent. The present method is facile and offers several advantages such as high % yield, less reaction time, and no use of additive/bases. Also, the catalyst showed better values of green metrics including low E-factor: 0.17, high reaction mass efficiency: 85.34%, high carbon efficiency: 94%, and high process mass intensity: 1.17.

Hybrid Co3O4/MnO2 nanotube-based catalysts were prepared by a simple hydrothermal synthesis method. The physico-chemical properties of Co3O4/MnO2 catalyst were then studied by different characterization techniques, namely, SEM, TEM and HR-TEM, XRD, BET surface area, XPS and H-2-TPR. The hybrid catalyst showed superior catalytic performance toward benzyl alcohol oxidation than pure MnO2 nanotubes and Co3O4 nanoparticles. The uniform dispersion of Co3O4 nanoparticles, good redox behaviour, the variable oxidation states of manganese and cobalt (Mn3+/4+ or Co3+/2+) as well as the abundance of active surface oxygen species were responsible for such a high catalytic activity.

As a widely used chemical material, bisphenol A (BPA) is often used to produce kinds of chemicals, which lead risk to the ecological environment and human health. Based on the multi-catalysis of the nano-ZnO and multi-effect (chemical and physical) formed in the dielectric barrier discharge plasma (DBDP) system, the synergistic elimination of the BPA in the DBDP system combined with nano-ZnO was evaluated. The obtained experimental results showed that the superior adding amount of the nano-ZnO was 50 mg/L and the synergistic system on the condition had the best effect for the BPA degradation (85.4%), which was 17% higher than that in the sole DBDP system. When O-2 was bubbled into the reaction system, the degradation efficiency of the BPA in the synergistic system reached 100% after 20 min treatment. Compared with the alkaline solution, the acidic and weakly acidic solution could obtain higher treatment efficiency. (OH)-O-center dot and O-2(-) had a vital role for the BPA elimination in the synergistic system. The intermediate products detected by LC-MS included 4-cumylphenol, 4-isopropenylphenol, 4-tert-butylphenol, propiophenone, 1-(4-hydroxyphenyl) ethanone, tert-butylbenzene, benzoquinone and 1, 4-dihydroxybenzene.

Transition-metal-catalyzed cross-electrophile C(sp(2))-(sp(3)) coupling and C-H alkylation reactions represent two efficient methods for the incorporation of an alkyl group into aromatic rings. Herein, we report a Pd-catalyzed cascade cross-electrophile coupling and C-H alkylation reaction of 2-iodo-alkoxylarenes with alkyl chlorides. Methoxy and benzyloxy groups, which are ubiquitous functional groups and common protecting groups, were utilized as crucial mediators via primary or secondary C(sp(3))-H activation. The reaction provides an innovative and convenient access for the synthesis of alkylated phenol derivatives, which are widely found in bioactive compounds and organic functional materials.

The volatile compounds of peaches (Prunus persica L.) obtained from five cultivars (Chongyanghong, Y1; Ruiguang 19, Y2; Zaohongxia, Y3; Zaohong 2, Y4; and Wuyuehuo, Y5) were analyzed by gas chromatography-olfactometry (GC-O), gas chromatography-mass spectrometry (GC-MS) and GC-flame photometric detection (FPD). A total of 40 odor-active volatile compounds were observed in the GC-O experiments. Amongst those compounds, hexanal, (Z)-3-hexen-1-ol, (E)-2-hexenal, 3-mercaptohexanol, nonanal, -nonalactone, and -decalactone contributed greatly to aroma of peach. In addition, thirty-four quantified compounds were demonstrated as important odorants according to odor activity values (OAVs>1). Amongst these compounds, hexanal (OAV: 28-89), pentanal (OAV: 9-16), (E)-2-heptenal (OAV: 19-60), (E)-2-hexenal (OAV: 26-86), (E)-2-octenal (OAV: 10-42), (E)-2-nonenal (OAV: 8-94), -decalactone (OAV: 13-34), -decalactone (OAV: 2-19), (R)-(-)-linalool (OAV: 29-76) and phenyl acetaldehyde (OAV: 4-59) were the most powerful compounds in five varieties of peach.

1-(4-methoxyphenyl)-3-(3, 4-dimethoxyphenyl)-2-propen-1-one(DMMC), a chalcone derivative was synthesized by Claisen-Schmidt condensation reaction method. The growth of DMMC in methanol was used the slow evaporation technique. Single crystal X-ray diffraction revealed that the space group of DMMC is P2(1). The intermolecular interaction of crystal was analyzed by Hirshfeld surface. The second harmonic generation efficiency of DMMC was measured by Kurtz-Perry powder method. When the particle size was between 250 and 300 mu m, the SHG efficiency of DMMC was the largest, which was about 60 times that of the KDP with the same particle size. All functional groups of the crystal were identified by FT-IR and H-1 NMR spectral. This crystal had a wide transmission range in the region of 350-2000 nm with the cut off wavelength is 400 nm. The thermal properties of the sample were tested, and the melting point was at 95.59 degrees C. The dielectric constant of the compounds was found to be 17 below 45 degrees C.

C-70 fullerene catalyzed photoinduced oxidation of benzylic amines at ambient conditions has been explored here. The developed strategy’s main feature includes the additive/oxidant-free conversion of benzylic amine to corresponding imine and aldehydes. The reaction manifests broad substrate scope with excellent function group leniency and is applicable up to the gram scale. Further, symmetrical secondary amines can also be synthesized from benzylic amine in a one-pot two-step process. Various experiments and density functional theory studies revealed that the current reaction involves the generation of reactive oxygen species, single electron transfer reaction, and benzyl radical formation as key steps under photocatalytic conditions.
