The Fujiwara-Moritani reaction is a powerful tool for the olefination of arenes by Pd-catalyzed C-H activation. However, the need for superstoichiometric amounts of toxic chem. oxidants makes the reaction unattractive from an environmental and atom-economical view. Herein, authors report the first non-directed and regioselective olefination of simple arenes via an electrooxidative Fujiwara-Moritani reaction. The versatility of this operator-friendly approach was demonstrated by a broad substrate scope which includes arenes, heteroarenes and a variety of olefins. Electroanal. studies suggest the involvement of a Pd(II)/Pd(IV) catalytic cycle via a Pd(III) intermediate. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Synthetic Route of 91-16-7

And the article contained the following:

A bissalamo-coumarin-based chem. sensor H4L was designed and synthesized. It was found that the sensor mol. can selectively recognize Cr3+ and Al3+. In a buffer solution system, its complex L – Cr3+ is highly sensitive to the detection of S2- anion, and the sensor H4L can recognize Cr3+ at an acceptable physiol. pH. Within the range, L – Cr3+ can recognize S2- anions with high selectivity and sensitivity. The detection limit for the sensor mol. H4L to recognize Cr3+ is 4.87 x 10-7 M, and the quenching constant with Cr3+ is 2.406 x 106 M-1. It was calculated that the detection limit of L – Cr3+ as a sensor was 8.23 x 10-7 M, and the binding constant with S2- anion was 1.44 x 106 M-1. The possible recognition mechanisms were discussed by UV, fluorescence titration, ESI-mass spectrometry and Job curve. In addition, S2- in different water samples was detected and the recovery was good. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application of 91-16-7

A. published an article.Application In Synthesis of 1,2-Dimethoxybenzene The title of the article was Theoretical O-CH3 bond dissociation enthalpies of selected aromatic and non-aromatic molecules. And the article contained the following:

Although Me transfer reactions are important in both chem. and biol. systems, there is a need for thermodn. parameters related to Me affinity and O-CH3 bond dissociation enthalpies (BDEs) relevant to a full understanding of the mechanisms of Me transfer reactions. As a prelude to the construction of a database of O-CH3 BDEs, the present work examines the reliability of a series of theor. methods for the prediction of O-CH3 BDEs using a set of 25 compounds that included both aromatic and non-aromatic mols. The BDEs calculated by d. functional theory (DFT) with traditional exchange-correlation functions exhibited much larger errors than those obtained by either the M06-2X or G4 methods. For the non-aromatic compounds, M06-2X/def2-TZVP performed slightly better than G4, but G4 was more accurate for the aromatic mols. As a result, we recommend G4 as the preferred method for the theor. estimation of O-CH3 bond dissociation enthalpies, although M06-2X may be a good alternative for large complex mols. when the use of G4 is impractical.

On April 30, 2020, MacKenzie, Ian A.; Wang, Leifeng; Onuska, Nicholas P. R.; Williams, Olivia F.; Begam, Khadiza; Moran, Andrew M.; Dunietz, Barry D.; Nicewicz, David A. published an article.Safety of 1,2-Dimethoxybenzene The title of the article was Discovery and characterization of an acridine radical photoreductant. And the article contained the following:

Photoinduced electron transfer (PET) is a phenomenon whereby the absorption of light by a chem. species provides an energetic driving force for an electron-transfer reaction1-4. This mechanism is relevant in many areas of chem., including the study of natural and artificial photosynthesis, photovoltaics and photosensitive materials. In recent years, research in the area of photoredox catalysis has enabled the use of PET for the catalytic generation of both neutral and charged organic free-radical species. These technologies have enabled previously inaccessible chem. transformations and have been widely used in both academic and industrial settings. Such reactions are often catalyzed by visible-light-absorbing organic mols. or transition-metal complexes of ruthenium, iridium, chromium or copper5,6. Although various closed-shell organic mols. have been shown to behave as competent electron-transfer catalysts in photoredox reactions, there are only limited reports of PET reactions involving neutral organic radicals as excited-state donors or acceptors. This is unsurprising because the lifetimes of doublet excited states of neutral organic radicals are typically several orders of magnitude shorter than the singlet lifetimes of known transition-metal photoredox catalysts7-11. Here we document the discovery, characterization and reactivity of a neutral acridine radical with a maximum excited-state oxidation potential of -3.36 V vs. a SCE, which is similarly reducing to elemental lithium, making this radical one of the most potent chem. reductants reported12. Spectroscopic, computational and chem. studies indicate that the formation of a twisted intramol. charge-transfer species enables the population of higher-energy doublet excited states, leading to the observed potent photoreducing behavior. We demonstrate that this catalytically generated PET catalyst facilitates several chem. reactions that typically require alkali metal reductants and can be used in other organic transformations that require dissolving metal reductants.

And the article contained the following:

Herein, a conjugated polymer and fullerene bearing architecture-based electrochem. Tyrosinase (Tyr) enzyme inhibition biosensor for indomethacin (INDO) drug active compound has been developed. For this purpose, three moieties of benzoxadiazole, thienopyrroledione, and benzodithiophene containing conjugated polymer; poly[BDT-alt-(TP;BO)] was used as a transducer modifier together with fullerene for catechol detection. The specific combination of these materials is considered an effective way to fabricate highly sensitive and fast response catechol biosensors for the first time. Electrochem. and surface characteristics of the modified electrodes were obtained by cyclic voltammetry, electrochem. impedance spectroscopy, SEM, and at. force microscopy. The effect of the parameters during chronoamperometric measurements on the biosensor response was also studied. Using optimized conditions, biosensing of catechol was achieved between 0.5 and 62.5 μM with a limit of the detection 0.11 μM. Tyr inhibition was followed with INDO drug active compound and it was found that INDO has a mixed type characteristic of enzyme kinetics with an I50 value of 15.11 μM.

And the article contained the following:

Open 1D channels found in covalent organic frameworks are unique and promising to serve as pathways for proton conduction; how to develop high-rate yet stable transporting systems remains a substantial challenge. Herein, this work reports a strategy for exploring proton-conducting frameworks by engineering pore walls and installing proton-containing polymers into the pores. Amide-linked and sulfonated frameworks were synthesized from imine-linked precursors via sequentially engineering to oxidize into amide linkages and to further anchor sulfonic acid groups onto the pore walls, enabling the creation of sulfonated frameworks with high crystallinity and channel ordering. Integrating sulfonated polyether ether ketone chains into the open channels enables proton hopping to across the channels, greatly increases proton conductivity and enables a stable continuous run. These results suggest a way to explore proton-conducting COFs via systematic engineering of the wall and space of the open nanochannels. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Product Details of 91-16-7

And the article contained the following:

A deeper knowledge of the causes of volatile organic compounds (VOCs) variance in wheat is crucial for quality improvement and control of its derivatives The VOCs profile of common and durum wheat kernels grown in different fields sited at different altitudes over two years was analyzed and 149 compounds were identified by gas chromatog.-mass spectrometry. Principal component anal. evidenced that the year of cultivation was the highest source of VOCs variance. The effects of wheat origin, as described by the cultivation site, its elevation, and species were further investigated by PLS-DA, that permitted to correctly classify wheat of different origin on the basis of its VOCs profile. The importance of the different effects was investigated by multidimensional test and resulted: year of cultivation > field of cultivation > species > altitude. Findings suggest that environmental conditions are more important than species in the determination of the VOCs variance of wheat.
