The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

In the non-thermal plasma catalysis system, VOCs degradation was significantly affected by the position of the catalyst, as well as operation mode. Hence, it is of great significance to evaluate the performance of In Plasma Catalysis (IPC) and Post Plasma Catalysis (PPC) systems for VOCs abatement using both continuous and sequential processes. Four packed-bed dielectric barrier discharge (DBD) systems were used to degrade toluene with different catalysts under diverse voltages in this study. Results showed that the IPC mineralization rates were higher as compared to PPC, regardless of whether the continuous or sequential processes was used, and irrespective of the applied voltage and type of packed catalyst (e.g. 77.00% and 96.06% in SPPC and SIPC at 20 kV with Ag/ZSM-5 packed). However, PPC was superior to IPC in O-3 and N2O reduction. As the applied voltage was raised, the mineralization rate in different reactors increased significantly, yet CO2 selectivity was insusceptible to voltage variation. NTP alone exhibited a mineralization rate and CO2 selectivity of 9.67%-22.62% and 53.85%-58.26%, respectively. While the mineralization rate and CO2 selectivity were remarkably improved with the presence of Ag/ZSM-5 (19.08%-41.59% and 93.99%-95.91% in CIPC). With respect to different catalysts investigated in this study, at 20 kV, Ag/ZSM-5 exhibited the highest mineralization rate – 96.06% in SIPC, and CO2 selectivity 98.43% in SPPC; while the lowest concentrations of O-3 (198 ppm) and N2O (8.01 ppm) were obtained in the Mn/ZSM-5 packed bed reactor. Possible reaction mechanisms were also proposed by analyzing the organic intermediates that were produced during continuous and sequential treatments, and remained in the adsorbents of IPC and PPC reactors.

Benzyl alcohol (BnOH) is a natural colorless liquid organic compound that plays an important role in bacteriostatic and anesthetic processes. It is also used to relieve the nerve and ganglionic pain. In this study, we assessed the effect of topical application of BnOH on the Achilles tendon healing process. Sprague Dawley rats were subjected to an experimentally induced wound in the tendon area and then randomized into four groups. Normal saline (0.5 mL) was applied to rats in control group, and BnOH at the concentrations of 0.5 mL 0.075%, 0.15%, 0.3% were applied to the BnOH treatment groups, respectively. Wound treatment with BnOH led to significantly faster functional recovery than with saline. Moreover, treatment of wounds with 0.3% BnOH accelerated the healing process faster than with 0.075% and 0.15% BnOH. Histological analysis of healed wounds that had been treated with BnOH showed more collagen and blood capillaries and fewer inflammatory cells compared to the control. To study the mechanism of the process, the expression of mRNA of TGF-beta 1, Smad2/3 and Smad7 and protein of TGF-beta 1, p-Smad2/3 and Smad7 were quantified by real-time PCR and Western blotting, respectively. Results of this study showed that wounds treated with BnOH significantly enhanced the expression of TGF-beta 1 and Smad2/3 and reduced the expression of Smad7. In general, the current study demonstrated that BnOH improved the recovery process of tendon healing through the promotion of collagen with angiogenesis and showed that TGF-beta plays a role in BnOH treatment of tendon healing.

A nickel-catalyzed arylation of both aliphatic and aromatic aldehydes proceeds with air-stable (hetero)arylboronic acids, with an exceptionally wide substrate scope. The neutral condition tolerates acidic hydrogen and sensitive polar groups and also preserves alpha-stereocenters of some chiral aldehydes. Interestingly, this nickel(0) catalysis does not follow common 1,2-insertion of arylmetal species to aldehydes and beta-hydrogen elimination.

In the presence of [p-cymene)RuCl2](2), (E)-configured alkenyl bromides couple with aromatic carboxylates to form orthovinylbenzoic acids. This C-H vinylation proceeds in high yields without any activating phosphine ligands and has an excellent functional group tolerance. Starting from commonly available (E/Z)-mixtures of alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.

A heterogeneous organic-inorganic hybrid durable nanocatalyst gamma-Al2O3@Silane-TMG was prepared by covalently functionalization of nano-gamma-Al2O3 through anchored 3-chloropropyl- trimethoxysilane with 1,1,3,3-tetramethylguanidine (TMG). The structure of the catalyst was characterized by various techniques including FT-IR, XRD, SEM, EDX and TGA analyses. The synthesized nanocatalyst was successfully used in an efficient and green four-component synthesis of pyrazolopyranopyrimidine derivatives using ethyl acetoacetate, hydrazine hydrate, arylaldehydes and barbituric acid (or thiobarbituric acid) in H2O at 40 oC. This practical method produced the desired products at reduced reaction times (10-25 min) and high to excellent yields (85-98%). The main advantages of this practical method are the use of heterogeneous basic nanocatalyst, simple work-up procedure with no need to chromatographic purification, affording highly selective conversion and recyclability of the catalyst which could be used in 5 cycles with only a small decrease in its activity.

Sacroflavonoside, a new derivative of diphenylethene, was isolated from Artemisia sacrorum, which have been found to possess the inhibitory effect on the proliferation of gastric carcinoma cells (MKN-45) in vitro in our previous studies. With anisaldehyde (SM-A) as starting material, the sacroflavonoside was synthesized by nucleophilic addition, electrophilic substitution and dehydration cyclization. The structure of sacroflavonoside was established by 1 D (H-1 NMR and C-13 NMR) and 2 D-NMR (HSQC and HMBC) spectral analysis. The antitumor activity and potential mechanism against MKN-45 cells of sacroflavonoside were evaluated in vitro. The results showed that sacroflavonoside could significantly induce MKN-45 cells apoptosis and autophagy by increasing the expression of Bax, Caspase-3, Beclin1 and LC3-II proteins and decreasing the expression of Bcl-2 protein at low micromole level. This investigation provided a valuable lead structure for the development of antitumor drugs. [GRAPHICS] .

A decarboxylative protocol has been developed toward a range of carbocycles. The key success is based on the use of a batch of newly designed cyclic carbonates as substrates that can provide carbon-carbon zwitterion intermediate under palladium catalysis. The kinetics of the reactions are controllable toward either strained seven- or thermodynamically more favored five-membered carbocycles. The release of this chemistry will shed light on the synthesis of complex and valuable cyclic structures.

Phosphite-based Au(i) catalytic systems containing an array of structurally diverse polyether-based regulation sites were designed and synthesised. These catalysts have been successfully tested in the Au(i)-catalysed C-H functionalisation of phenols and related derivatives with gold-carbenes derived from diazo compounds. Regulation of the steric congestion around the catalytic Au(i) centreviaion-dipole interactions with an external regulation agent led to an enhancement of both the activity and selectivity of the reaction. This new approach in supramolecular gold(i) catalysis has been applied to the derivatisation of an array of substituted phenols and related substrates and to the preparation of an advanced synthetic intermediate of the anticancer agent tamoxifen. The effects of the regulation agent on the selectivity and yield of the reaction have been studied and rationalised using DFT-D calculations.

The Meerwein-Ponndorf-Verley (MPV) reaction is an attractive approach to selectively reduce carbonyl groups, and the design of advanced catalysts is the key for these kinds of interesting reactions. Herein, we fabricated a novel zirconium organoborate using 1,4-benzenediboronic acid (BDB) as the precursor for MPV reduction. The prepared Zr-BDB had excellent catalytic performance for the MPV reduction of various biomass-derived carbonyl compounds (i.e., levulinate esters, aldehydes and ketones). More importantly, the number of borate groups on the ligands significantly affected the catalytic activity of the Zr-organic ligand hybrids, owing to the activation role of borate groups on hydroxyl groups in the hydrogen source. Detailed investigations revealed that the excellent performance of Zr-BDB was contributed by the synergetic effect of Zr4+ and borate. Notably, this is the first work to enhance the activity of Zr-based catalysts in MPV reactions using borate groups.
