On April 28, 2021, Zhang, Zhenfei; Liu, Yong; Portaluri, Vincent; Woodcock, Christine; Pickett, John A.; Wang, Senshan; Zhou, Jing-Jiang published an article.Recommanded Product: 1,2-Dimethoxybenzene The title of the article was Chemical Identity and Functional Characterization of Semiochemicals That Promote the Interactions between Rice Plant and Rice Major Pest Nilaparvata lugens. And the article contained the following:

The interaction between food crops and insect pests is mediated by semiochems. emitted from host plants. These semiochems. are natural behavioral modifiers and act on the insect olfactory system to locate hosts and preys. In this study, eight rice neuroactive semiochems. were identified from rice varieties by GC-EAG and GC-MS. Their ability to modify rice pest behaviors was further studied as individual chems. and physiol. relevant blend. The total amount of each semiochem. and the expression of their biosynthesis genes were significantly higher in pest susceptible variety than in pest-resistant variety and upregulated by the infestation of the pest Nilaparvata lugens (BPH). The semiochems. emitted by uninfested plants (UIRVs) were more attractive to BPHs. Interestingly, the attractiveness of UIRVs was significantly reduced by the addition of the blend that mimics the natural composition of these semiochems. emitted by infested plants (IRVs). Our study suggests a mechanism for the spread of pest infestation from infested plants to uninfested plants nearby. UIRVs initially serve as attractive signals to rice insect pests. The pest infestation changes the rice semiochem. profile to be less attractive or even repellent, which pushes further colonization to uninfested plants nearby. The identified semiochems. can be used for crop protection based on a push-pull strategy. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 1,2-Dimethoxybenzene

On June 15, 2022, Wang, Wenhui; Gao, Wei; Nie, Xinhao; Liu, Weihua; Cheng, Xiang; Shang, Ningzhao; Gao, Shutao; Wang, Chun published an article.Computed Properties of 150-78-7 The title of the article was Photocatalytic selective amines oxidation coupled with H2O2 production over hyper-cross-linked polymers. And the article contained the following:

Herein, a series of hyper-cross-linked polymers (HCPs) photocatalysts were synthesized through Friedel-Crafts alkylation reaction, in which benzene served as monomer and dichloromethane (DCM), dichloroethane (DCE) as well as 1,4-dimethoxybenzene (DMB) served as crosslinker. It was found that different crosslinker can change the energy level of conduction and valence band of HCPs, which is crucial for the generation of reactive oxygen species (ROS), and the separation efficiency as well as mobility of photo-generated carriers. Among of these prepared HCPs photocatalysts, DCM-HCPs exhibited highest conversion and selectivity toward benzylamine oxidation under the irradiation of blue LED lamp (455 nm) and sunlight in air atm. The highest apparent quantum yield (AQY) of DCM-HCPs is 0.44%. More importantly, a high yield of H2O2 (TOF = 5712.67 μmol g-1cat h-1) was synchronously obtained during the process of benzylamine oxidation Synchronous-illumination XPS (SI-XPS) was used to investigate the charge transfer mechanism of HCPs. The results revealed that the photoelectrons transferred from crosslinker (-CH2-) to benzene ring for inducing benzylamine oxidation to N-benzylidenebenzylamine and H2O2 production In addition, a series of amines and sulfides can also be smoothly oxidized at the similar conditions. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Computed Properties of 150-78-7

Hamby, Taylor B.; LaLama, Matthew J.; Sevov, Christo S. published an article in 2022, the title of the article was Controlling Ni redox states by dynamic ligand exchange for electroreductive C(sp3)-C(sp2) coupling.Related Products of 93-04-9 And the article contains the following content:

Cross-electrophile coupling (XEC) reactions of aryl and alkyl electrophiles are appealing but limited to specific substrate classes. Here, electroreductive XEC of previously incompatible electrophiles including tertiary alkyl bromides, aryl chlorides, and aryl/vinyl triflates are reported. The reactions rely on the merger of an electrochem. active complex that selectively reacts with alkyl bromides through 1e- processes and an electrochem. inactive Ni0(phosphine) complex that selectively reacts with aryl electrophiles through 2e- processes. Accessing Ni0(phosphine) intermediates is critical to the strategy but is often challenging. Here, a previously unknown pathway for electrochem. generating these key complexes at mild potentials through a choreographed series of ligand-exchange reactions has been uncovered. The mild methodol. is applied to the alkylation of a range of substrates including natural products and pharmaceuticals. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Related Products of 93-04-9

On July 31, 2014, Vaz, Raquel V.; Magalhaes, Ana L.; Silva, Carlos M. published an article.Product Details of 321-28-8 The title of the article was Prediction of binary diffusion coefficients in supercritical CO2 with improved behavior near the critical point. And the article contained the following:

In this work, a predictive model for binary diffusivities at infinite dilution (D12) in SC-CO2 is proposed. It combines two terms – background and singular – with the objective to represent D12 accurately not only far but also near the critical point, where critical enhancement is always observed The model provides an average error of 6.20% for a large database including 149 systems and 4469 data points over wide ranges of temperature and pressure. The models selected for comparison (Wilke-Chang, Scheibel, Lusis-Ratcliff, Lai-Tan, Tyn-Calus and Reddy-Doraiswamy) achieve scattered and biased results, with average errors from 11.62-75.17%. In the whole, the new model exhibits an excellent performance for any kind of mols. in terms of size, mol. weight, polarity and sphericity, in all critical region. In order to help interested readers, a spreadsheet for the calculation of D12 is given in supplementary data. The input data is: temperature, pressure, CO2 viscosity, and solute properties (acentric factor, critical constants, molar volume at normal b.p., and mol. weight – given in this paper for the systems studied). The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Product Details of 321-28-8

A novel photoinduced strategy has been developed for the C-H amidation of aromatics and heteroaromatics by using benzamide radicals such as 1,3,5-trimethylbenzene, 1-methoxynaphthalene, 1-methyl-1H-indole, 1-methyl-1H-pyrrole, etc. with free NH groups generated from N-amidopyridinium salts such as as 1-benzamido-2,4,6-triphenylpyridin-1-ium tetrafluoroborate under visible-light irradiation The new mode of activation of N-amidopyridinium salts proceeds efficiently under mild conditions to give various benzamide derivatives RNHC(O)C6H5 (R = 2,4,6-trimethylphenyl, 1-methoxynaphthalen-2-yl, 1-methyl-1H-indol-3-yl, etc.) with free NH groups. In addition, oxazoline analogs, synthesized by the reaction with styrene, demonstrate a substantial range of prospective applications for this versatile protocol.
