And the article contained the following:

A new nitrogen-rich microporous polymer (PAN-FPP5) containing pillar[5]arene macrocycles was fabricated via facile polycondensation between pillar[5]arene-based monomer (FPP5) bearing two aldehyde moieties and melamine. Compared with the macrocycle-free category, PAN-FPP5 exhibited superior CO2 uptake (12.5 wt % vs 9.9 wt %, 273 K/1 bar) and selectivity of CO2/N2 (55.6 vs 39.9, 298 K). In addition, PAN-FPP5 also displayed an excellent capability of removal of iodine in both solvent and vapor phases because of the electron-rich property of pillar[5]arene. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Electric Literature of 150-78-7

On June 30, 2014, Wu, Xiaoqin; Bai, Peng; Guo, Xianghai; He, Nana published an article.Quality Control of 1-Fluoro-2-methoxybenzene The title of the article was 2,4-Difluoroanisole: a promising complexing agent for boron isotopes separation by chemical exchange reaction and distillation. And the article contained the following:

Although methods of boron isotopes separation were intensively pursued about 60 years, the chem. exchange distillation is the only method that has been applied in industrial scale production of 10B. The present anisole BF3 system suffers from the drawbacks like high m.p., relatively low separation coefficient and instability under reaction conditions, which demand a continuous search for more effective and efficient donors for boron isotope separation A series of fluoro-substituted anisole derivatives were screened in this paper, among which 2,4-difluoroanisole exhibited good properties compared with anisole. Studies on the boron trifluoride and 2,4-difluoroanisole adduct, its thermodn. and phys. properties related to large-scale isotopic separation is reported. The results showed that 2,4-difluoroanisole is better than anisole in separation coefficient, f.p. and stability under pyrolysis conditions, which suggest a further detailed investigations on boron trifluoride and 2,4-difluoroanisole adduct. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Quality Control of 1-Fluoro-2-methoxybenzene

On May 22, 2019, Zhang, Yongqian; Tamijani, Ali A.; Taylor, Megan E.; Zhi, Bo; Haynes, Christy L.; Mason, Sara E.; Hamers, Robert J. published an article.SDS of cas: 929-37-3 The title of the article was Molecular Surface Functionalization of Carbon Materials via Radical-Induced Grafting of Terminal Alkenes. And the article contained the following:

Formation of functional monolayers on surfaces of carbon materials is inherently difficult because of the high bond strength of carbon and because common pathways such as SN2 mechanisms cannot take place at surfaces of solid materials. Here, we show that the radical initiators can selectively abstract H atoms from H-terminated carbon surfaces, initiating regioselective grafting of terminal alkenes to surfaces of diamond, glassy carbon, and polymeric carbon dots. NMR and XPS demonstrate formation of self-terminating organic monolayers linked via the terminal C atom of 1-alkenes. D. functional theory (DFT) calculations suggest that this selectivity is at least partially thermodn. in origin, as significantly less energy is needed to abstract H atoms from carbon surfaces as compared to typical aliphatic compounds The regioselectivity favoring binding to the terminal C atom of the reactant alkenes arises from steric hindrance encountered in bond formation at the adjacent carbon atom. Our results demonstrate that carbon surface radical chem. yields a versatile, selective, and scalable approach to monolayer formation on H-terminated carbon surfaces and provide mechanistic insights into the surface selectivity and regioselectivity of mol. grafting. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).SDS of cas: 929-37-3

Transfer of electrophilic NH to sulfides and a subsequent sulfimine-promoted fast O transfer was achieved in a one-pot process unprecedentedly for the preparation of sulfoximines, e.g., I at ambient temperature under air. The transformations, which are metal-, ligand-, base-, additive-free, and operationally simple, proceeded in just 5 min and furnished NH-sulfoximines in good-to-excellent yields (up to 99 %) by treatment of sulfides with a combination of PhI(OAc)2 and ammonia source. A variety of com. available and inexpensive electrophilic nitrogen sources were successfully used in the oxidative sulfide-to-sulfoximine conversions. This method featured a high efficiency, excellent functional-group tolerance, and broad substrate scope, which may facilitate its applications in medicinal chem. area. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Application of 53136-21-3

On October 7, 2020, Tuo, Wei; Sun, Yan; Lu, Shuai; Li, Xiaopeng; Sun, Yao; Stang, Peter J. published an article.Product Details of 150-78-7 The title of the article was Pillar[5]arene-Containing Metallacycles and Host-Guest Interaction Caused Aggregation-Induced Emission Enhancement Platforms. And the article contained the following:

Coordination-driven Pt metallacycles have shown potential in controllable modular self-assembly, which has made a vital contribution to biomedicine, catalysis, and multiresponsive materials. Herein, pillar[5]arene units were integrated into one skeleton through coordination-driven self-assembly, resulting in the formation of a hexagonal Pt(II) metallacycle decorated with six pillar[5]arenes. The host-guest interactions of the as-prepared metallacycle (pillar[5]arenes as hosts) and 1-butyl-4-[4-(diphenylamino)styryl]pyridinium (guest) were investigated. The metallacycle was found to facilitate the coaggregation between the guests and pillar[5]arenes through a synergistic effect, thus engendering a sharp increase in fluorescence intensity. The resultant aggregate was investigated by DLS and TEM. Our studies imply that the pillar[5]arene-containing metallacycle can serve as a potential platform for realizing emission enhancement effects. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Product Details of 150-78-7

On November 6, 2015, Miranda, Luis D.; Hernandez-Vazquez, Eduardo published an article.Related Products of 887581-09-1 The title of the article was Multicomponent/Palladium-Catalyzed Cascade Entry to Benzopyrrolizidine Derivatives: Synthesis and Antioxidant Evaluation. And the article contained the following:

A versatile and efficient protocol for the synthesis of highly substituted benzopyrrolizidines (tetrahydro-3H-pyrrolo[2,1-a]isoindol-3-ones) is reported. The strategy consisted of an Ugi four-component reaction/elimination methodol. to afford dehydroalanines containing trans-cinnamic acid derivatives and different substituted 2-bromobenzylamines, followed by a palladium-catalyzed 5-exo-trig/5-exo-trig cascade carbocyclization process. Gratifyingly, benzopyrrolizidines, e.g. I, were obtained in moderate to good yields (42-77%) with a Z geometry due to the structural requirements for syn-β-hydride elimination. The prepared heterocyclic scaffolds are decorated with several substituents and incorporate a benzopyrrolizidine-fused system, along with an embedded cinnamic acid derivative, two privileged medicinal chem. scaffolds. Addnl., since some of the compounds are derived from the well-known antioxidants ferulic and sinapinic acids, they were tested for their in vitro antioxidant capacity. The data suggested that compounds having a p-hydroxyl group showed moderate 2,2-diphenyl-1-picrylhydrazyl-radical-scavenging activity and were effective antioxidants in preventing lipoperoxidation in a thiobarbituric acid reactive substances assay. The experimental process involved the reaction of (2-Bromo-5-methoxyphenyl)methanamine(cas: 887581-09-1).Related Products of 887581-09-1
