And the article contained the following:

Herein, we report a rhodium catalyzed directing-group free regioselective C-H allylation of simple arenes. Readily available gem-difluorinated cyclopropanes can be employed as highly reactive allyl surrogates via a sequence of C-C and C-F bond activation, providing allyl arene derivatives in good yields with high regioselectivity under mild conditions. The robust methodol. enables facile late-stage functionalization of complex bioactive mols. The high efficiency of this reaction is also demonstrated by the high turnover number (TON, up to 1700) of the rhodium catalyst on gram-scale experiments Preliminary success on kinetic resolution of this transformation is achieved, providing a promising access to enantio-enriched gem-difluorinated cyclopropanes.

On November 5, 2020, Zhang, Cheng; Li, Jiaohong; Wu, Xiaomao; Long, Youhua; An, Huaming; Pan, Xinglu; Li, Ming; Dong, Fengshou; Zheng, Yongquan published an article.Recommanded Product: 1,2-Dimethoxybenzene The title of the article was Rapid degradation of dimethomorph in polluted water and soil by Bacillus cereus WL08 immobilized on bamboo charcoal-sodium alginate. And the article contained the following:

The presence of hazardous dimethomorph residues in the environment poses a threat to birds, aquatic organisms, and mammals. The novel pure strain, Bacillus cereus WL08, responsible for detoxifying dimethomorph was isolated from dimethomorph-polluted soil. The WL08 immobilized system was developed using bamboo charcoal (BC) and sodium alginate (SA). Immobilization significantly improved the WL08 tolerance and stability. Under optimal conditions (pH 7.0 and 30°), free and immobilized WL08 degraded 66.95 and 96.88% of 50 mg/L dimethomorph within 72 h, resp. WL08 effectively degraded dimethomorph to simple products which had lower toxic than dimethomorph. In a continuous reactor, immobilized WL08 removed 85.61% of dimethomorph for 30 days at a 50-100 mg/L influent concentration For field soil sprayed with 4.20 kg a.i./ha 80% dimethomorph water dispersible granules with immobilized WL08, a lower half-life (1.93 days) was observed vs. free WL08 (4.28 days) and natural dissipation (23.82 days). Immobilized WL08 is considered a tool to remove dimethomorph from water/soil systems. Results provided a feasible, microbe-based strategy to bioremediate dimethomorph-polluted environments. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 1,2-Dimethoxybenzene

On June 15, 2021, Wang, Juan; Ming, Yuezhang; Li, Youming; Huang, Mingquan; Luo, Siqi; Li, Huifeng; Li, Hehe; Wu, Jihong; Sun, Xiaotao; Luo, Xuelian published an article.Application of 91-16-7 The title of the article was Characterization and comparative study of the key odorants in Caoyuanwang mild-flavor style Baijiu using gas chromatography-olfactometry and sensory approaches. And the article contained the following:

Caoyuanwang Baijiu (CYW), a mild-flavor style Baijiu (MSB), is popular in northern China. However, there is a lack of studies reporting its aroma-active components. The aroma compounds of five CYW samples were analyzed using gas chromatog.-olfactory-mass spectrometry coupled with aroma extraction dilution anal. Fifty-five aroma-active compounds were identified in CYW, of which 27 had odor activity values ≥ 1. Reconstituted models successfully simulated the aroma profiles of CYW. The omission tests elucidated that β-damascenone, di-Me trisulfide, Et pentanoate, butanoic acid, Et acetate, 3-methylbutanal, Et lactate, hexanoic acid, γ-nonalactone, 3-hydroxy-2-butanone, Et butanoate, 1-propanol, 4-(ethoxymethyl)-2-methoxy-phenol, and vanillin were key odorants in CYW. The addition test confirmed the significant influence of di-Me trisulfide on Chen-aroma note. Nine key odorants were identified as the differential quality-markers, and 85.71% key odorants were predicted using the partial least square regression (PLSR) anal., indicating the applicability of PLSR in selecting the target compounds for omission tests. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application of 91-16-7

On July 16, 2021, Thorwart, Thaddaus; Roth, Daniel; Greb, Lutz published an article.Quality Control of 1,2-Dimethoxybenzene The title of the article was Bis(pertrifluoromethylcatecholato)silane: Extreme Lewis Acidity Broadens the Catalytic Portfolio of Silicon. And the article contained the following:

Given its earth abundance, Si is ideal for constructing Lewis acids of use in catalysis or materials science. Neutral silanes were limited to moderate Lewis acidity, until halogenated catecholato ligands provoked a significant boost. However, catalytic applications of bis(perhalocatecholato)silanes were suffering from very poor solubility and unknown deactivation pathways. The novel per(trifluoromethyl)catechol, H2catCF3, and adducts of its Si complex Si(catCF3)2 (1) are described. According to the computed F- ion affinity, 1 ranks among the strongest neutral Lewis acids currently accessible in the condensed phase. The improved robustness and affinity of 1 enable deoxygenations of aldehydes, ketones, amides, or phosphine oxides, and a carbonyl-olefin metathesis. All those transformations have never been catalyzed by a neutral silane. Attempts to obtain donor-free 1 attest to the extreme Lewis acidity by stabilizing adducts with even the weakest donors, such as benzophenone or hexaethyl disiloxane. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Quality Control of 1,2-Dimethoxybenzene

On April 4, 2000, Neef, C. J.; Ferraris, J. P. published an article.Related Products of 146370-51-6 The title of the article was MEH-PPV: Improved Synthetic Procedure and Molecular Weight Control. And the article contained the following:

Mechanistic studies on the polymerization of α,α’-dibromo-2-methoxy-5-(2-ethylhexyloxy)xylene have been performed. Polymerizations were initially carried out by adding potassium tert-butoxide to monomer in the presence of a chain transfer agent, anthracene. Anthracene showed little effect on the mol. weight of the resulting polymer, suggesting that the major polymerization route was not radically initiated. Polymerizations were also carried out by adding monomer to potassium tert-butoxide in presence of a nucleophile, 4-methoxyphenol. The mol. weight of the resulting polymer scaled linearly with the amount of 4-methoxyphenol, suggesting an anionic mechanism. In addition, each polymerization was monitored by in-situ torque measurements to further elucidate the polymerization mechanism and optimize polymerization conditions. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Related Products of 146370-51-6
