Selective oxidation of organic substrates by environment-friendly oxidizing agents is an important ingredient of the sustainable chem. industry. Here we report a comprehensive study in the field of metal peoroxocomplex catalysis for the selective liquid phase oxidation of various organic substrates. A number of well-defined bi-functional tungsten complex catalysts with tetra nuclear structure {PO4[WO(O₂)₂]₄}^3- in combination with a phase-transfer agents were synthesized. The structural properties were thoroughly studied using of IR, Raman and EXAFS spectroscopy. By combining different spectroscopy techniques were able to elucidate the effect of quaternary ammonium cations on the structural properties of the resulting peroxo complexes. The catalytic properties of these well-defined material were then evaluated in bi-phasic selective oxidation of cyclooctene, Me oleate and N-phosphonomethyliminodiacetic acid with hydrogen peroxide under mild conditions. For every substrate we were able to achieve high conversion at the selectivity towards a target product close to 100%. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Product Details of 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Product Details of 5137-55-3

Non-aqueous reverse micelles created with a cationic surfactant: Encapsulating ethylene glycol in BHDC/non-polar solvent blends was written by Agazzi, Federico M.;Falcone, R. Dario;Silber, Juana J.;Correa, N. Mariano. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2016.Electric Literature of C25H46ClN The following contents are mentioned in the article:

We present results on a new system that forms non-aqueous reverse micelles (RMs) created with a cationic surfactant, benzyl-n-hexadecyldimethylammonium chloride (BHDC), encapsulating ethylene glycol (EG), in different nonpolar solvents blends of n-heptane:benzene. It is shown that a cationic surfactant forms RMs using EG as polar solvent without the addition of a co-surfactant. In particular, we analyzed the EG solubilization capacity, the droplet size values and the interface composition of EG/BHDC/n-heptane:benzene RMs, using dynamic light scattering (DLS) and the solvatochromic behavior of 1-methyl-8-oxyquinolinium betaine (QB) as mol. dye. The EG solubilization capacity depends on the external phase composition decreasing when the n-heptane content increases. Using DLS technique, we demonstrate the formation of RMs, and observe that for the same [EG]/[BHDC] ratio, the micellar size increases when n-heptane content increases. Using QB it was found that EG penetrates into the micellar interface changing dramatically the composition and the droplet-droplet interaction, in comparison when water is encapsulated. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Electric Literature of C25H46ClN

High-performance oxygen reduction reaction (ORR) catalysts are important for the application of proton exchange membrane fuel cell (PEMFC); electrodeposition of Pt-based catalysts is a viable method for its good controllability and operation. The exploration of green electrodeposition technol. with ionic liquids (ILs) or other non-aqueous solvent like deep eutectic solvents (DESs) has attracted much attention for their property to obtain high-performance catalysts with various morphologies. Composed of diverse organic cations and inorganic or organic anions, there are various types of ILs and DESs; efficient methods are urgently needed to screen potential ILs or non-aqueous solvent for electrodeposition. Computational approach is more economical, time-saving, and effective than conventional experiments In this study, the compatibility of 9 Pt salts in 13 ILs and DESs mixtures was studied to identify metal salts with good solubility in ILs and DESs. Simulation results show that the Reline and H2PtCl6 is the most suitable mixture with good compatibility at 298 K, maintaining good solubility after heating to 353 K. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6SDS of cas: 13820-53-6).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides.

Carbonyl reductase, as biocatalyst, is very important to chiral alcs. production through asym. reduction of carbonyl compound A novel thermal stable carbonyl reductase from Bacillus cereus (BcCR) dependent on NADPH was obtained through a new genome mining strategy proposed in this work. By analyzing its amino acid sequence and structure, the BcCR should be a thermal stability and wide pH tolerance carbonyl reductase. Its gene was cloned by PCR with B. cereus genomic DNA as template. Its heterologous expression system, E. coli BL21 (DE3) plysS/pET28a-bccr, was constructed, and BcCR was successfully expressed. Enzymic properties show that at 57.5 °C and pH 7.0 it can reach maximum reaction rate. Its K_m and V_max to Et 4-chloroacetoacetate is 1.85 mmol/L and 0.22 μmol/(min·mg_protein), resp. It can catalyze the asym. reduction of the β-carbonyl compound, such as Et 4-chloroacetoacetate to Et S-4-chloro-3-hydroxybutyrate. This paper proposes a practical method for discovery of new carbonyl reductases, and provides a novel enzyme as biocatalyst for asym. reduction of β-carbonyl compound This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Recommanded Product: Ethyl 4-chloro-3-oxobutanoate).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Recommanded Product: Ethyl 4-chloro-3-oxobutanoate

PdPtRu nanocages with tunable compositions for boosting the methanol oxidation reaction was written by Leng, Zihan;Wu, Xingqiao;Li, Xiao;Li, Junjie;Qian, Ningkang;Ji, Liang;Yang, Deren;Zhang, Hui. And the article was included in Nanoscale Advances in 2022.COA of Formula: Cl4Na2Pd The following contents are mentioned in the article:

PtRu/C is a well-known com. electrocatalyst with promising performance for the methanol oxidation reaction (MOR). Further improving the MOR properties of PtRu-based electrocatalysts is highly desirable, especially through structure design. Here we report a facile approach for the synthesis of PdPtRu nanocages with different components through a seed-mediated approach followed by chem. etching. The Pd-PtRu nanocubes were first generated using Pd nanocubes as the seeds and some Pd atoms were subsequently etched away, leading to the nanocages. When evaluated as electrocatalysts for the MOR in acidic media, the PdPtRu nanocages exhibited substantially enhanced catalytic activity and stability relative to com. Pt/C and PtRu/C. Specifically, PdPt₂.₅Ru₂.₄ achieved the highest specific (8.2 mA cm^-2) and mass (0.75 mA mgPt^-1) activities for the MOR, which are 2.2 and 4.2 times higher than those of com. Pt/C. Such an enhancement can be attributed to the highly open structure of the nanocages, and the possible synergistic effect between the three components. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6COA of Formula: Cl4Na2Pd).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.COA of Formula: Cl4Na2Pd

A near infrared fluorescent probe for the detection and imaging of prolyl aminopeptidase activity in living cells was written by Liu, Xianjun;Zhang, Quan-Yu;Wang, Fenglin;Jiang, Jian-Hui. And the article was included in Analyst (Cambridge, United Kingdom) in 2019.Computed Properties of C6H5ClO2 The following contents are mentioned in the article:

Prolyl aminopeptidase (PAP) is an important exopeptidase which might be a biomarker for pathogen infection and a potential therapeutic target. However, very few fluorescent probes have been developed for detecting PAP activity. Here we report the development of the first near IR (NIR) turn-on fluorescent probe (NIR-PAP) for detecting and imaging PAP in living cells. The probe is prepared by reacting a cysteine-proline dipeptide with an acryloylated NIR fluorophore via a facile thiol-Michael addition reaction. NIR-PAP exhibits a dynamic response toward PAP in the range of 0.02-2.5 U mL^-1 with an estimated limit of detection of 0.013 U mL^-1. In vitro studies also reveal that the probe displays high specificity and robust responses toward PAP under physiol. pH and temperature conditions. Moreover, NIR-PAP is successfully introduced to detect and differentiate PAP activity in four different cell lines via both confocal fluorescence imaging and flow cytometry. Therefore, our probe may hold great promise in diagnosing infectious diseases caused by pathogens and screening therapeutic drugs in vivo. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Computed Properties of C6H5ClO2).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.

Gold Nanoearbuds: Seed-Mediated Synthesis and the Emergence of Three Plasmonic Peaks was written by Roy, Debashree;Xu, Yi;Rajendra, Ranguwar;Wu, Lin;Bai, Ping;Ballav, Nirmalya. And the article was included in Journal of Physical Chemistry Letters in 2020.Electric Literature of C25H46ClN The following contents are mentioned in the article:

We demonstrate the first successful synthesis of reasonably monodisperse and single-crystalline gold nanoearbuds (Au NEBs) using a binary surfactant mixture of cetyltrimethylammonium chloride (CTAC) and benzyldimethylhexadecylammonium chloride (BDAC) in seed-mediated growth method. We have focused on the key chem. parameters behind the formation and growth of Au NEBs to result in tunable dimensions (length, 37-77 nm; width, 4-6 nm; aspect ratio, 7-19), as a consequence of which the longitudinal surface plasmon resonance (LSPR) peak could be tuned beyond 1200 nm. The achievement of LSPR beyond 1200 nm while maintaining the dimension well below 100 nm is a challenging accomplishment in the realm of one-dimensional (1D) Au nanostructures. This earbud-like morphol. addnl. exhibits three plasmonic peaks, rather uncommon for 1D nanostructures, which were analyzed theor. based on the finite element method. The new resonance peak of the Au NEB was assigned as an addnl. longitudinal mode intensified by the bulbous ends as well as the high aspect ratio, thereby providing conclusive evidence that it is indeed a new morphol. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Electric Literature of C25H46ClN

A microbial electrochem. system could potentially be applied as a biosynthesis platform by extracting wastewater energy while converting it to value-added chems. However, the unfavorable thermodn. and sluggish kinetics of in vivo whole-cell cathodic catalysis largely limit product diversity and value. Herein, we convert the in vivo cathodic reaction to in vitro enzymic catalysis and develop a microbe-enzyme hybrid bioelectrochem. system (BES), where microbes release the electricity from wastewater (anode) to power enzymic catalysis (cathode). Three representative examples for the synthesis of pharmaceutically relevant compounds, including halofunctionalized oleic acid based on a cascade reaction, (4-chlorophenyl)-(pyridin-2-yl)-methanol based on electrochem. cofactor regeneration, and l-3,4-dihydroxyphenylalanine based on electrochem. reduction, were demonstrated. According to the techno-economic anal., this system could deliver high system profit, opening an avenue to a potentially viable wastewater-to-profit process while shedding scientific light on hybrid BES mechanisms toward a sustainable reuse of wastewater.

Atomic vibrations and phonons are an excellent source of information on nanomaterials that the authors can access through a variety of methods including Raman scattering, IR spectroscopy, and EELS. In the presence of a plasmon local field, vibrations are strongly modified and, in particular, their dipolar strengths are highly enhanced, thus rendering Raman scattering and IR spectroscopy extremely sensitive techniques. Exptl. the interaction between a relativistic electron and vibrational modes in nanostructures is fundamentally modified in the presence of plasmons. The authors finely tune the energy of surface plasmons in metallic nanowires in the vicinity of hexagonal BN, making it possible to monitor and disentangle both strong phonon-plasmon coupling and plasmon-driven phonon enhancement at the nanometer scale. Because of the near-field character of the electron beam-phonon interaction, optically inactive phonon modes are also observed Besides increasing the understanding of phonon physics, the results hold great potential for studying sensing mechanisms and chem. in complex nanomaterials down to the mol. level.

Facile Synthesis of Pd and PdPtNi Trimetallic Nanosheets as Enhanced Oxygen Reduction Electrocatalysts was written by Shi, Lijie;Wang, Qian;Ren, Quan;Yang, Qian;Zhao, Donghui;Feng, Yuhua;Chen, Hongyu;Wang, Yawen. And the article was included in Small in 2022.Application of 13820-53-6 The following contents are mentioned in the article:

While bimetallic 2D metallic nanomaterials are widely synthesized and used as electrocatalysts with enhanced performance, trimetallic 2D structures are less commonly reported. In this work, a facile wet chem. method for synthesizing Pd nanosheets and PdPtNi trimetallic alloy nanosheets is developed. Without the introduction of gaseous CO and pressurized equipment, Pd nanosheets with a thickness of ≈2.85 nm and sizes in the range of 1-2μm can be obtained. The facile synthesis conditions allow for a comprehensive study of the nanosheet growth mechanism. It is found that 2D growth is closely related to the product of solvent decomposition and the additive ligand diethylenetriamine. Further, by depositing Pt and Ni onto the Pd nanosheets, trimetallic nanosheets with tunable compositions can be obtained and applied as oxygen reduction reaction electrocatalysts. Typically, the Pd₉Pt₁Ni₁ nanosheets have the highest half-wave potential of 0.928 V (vs reversible hydrogen electrode), which is 34 mV higher than that of com. Pt/C and 28 mV higher than that of Pd/C, and also have high durability.
