The article was titled 《Synthesis of C4-substituted coumarins via Pechmann condensation catalyzed by sulfamic acid. Insights into the reaction mechanism by HRMS analysis》.SDS of cas: 150-19-6 The article contains the following contents:

A series of functionalized C4-substituted coumarins were synthesized by exploring the reaction of activated and non-activated phenols and β-ketoesters under solvent-free conditions in the presence of sulfamic acid as a Bronsted acid catalyst. Fifteen examples were prepared with moderate to excellent yields (50% to 90%) using 10 mol % of the catalyst. Furthermore, it was possible from the proposed methodol. to scale up the synthesis of coumarins to obtain up to 11 g of product. This work also provides a preliminary insight into the reaction mechanism using high-resolution mass spectrometry anal. The key cinnamic acid derivative intermediate was detected, implying that under the evaluated conditions, the mechanistic pathway starts with an aromatic electrophilic substitution followed by dehydration reaction and intramol. transesterification. In the part of experimental materials, we found many familiar compounds, such as m-Methoxyphenol(cas: 150-19-6SDS of cas: 150-19-6)

Li, Xiaojiang; Sun, Leitao; Lv, Xin; Qi, Jie; Lu, Hongsheng; Wu, Yuanpeng; wang, Baogang published an article in 2021. The article was titled 《Sustainable separation of petroleum hydrocarbons pollutant using hydrophobic deep eutectic solvents regulated by CO2》, and you may find the article in Journal of Environmental Chemical Engineering.HPLC of Formula: 150-19-6 The information in the text is summarized as follows:

Petroleum hydrocarbons pollutants are the serious environmental hazards in the exploitation of petroleum resources. As comparison to the traditional solvent for petroleum hydrocarbons removal, deep eutectic solvents (DESs), as the ideal alternate for organic solvents, have non-toxicity, non-flammability and lower volatility. Whereas, the recycling of DES is still the great challenge for sustainable separation Herein, hydrophobic DESs (HDESs) with the CO2 switchable-hydrophilicity are developed, aiming to sustainably sep. petroleum hydrocarbons pollutions. The HDESs are formed by hydrogen bonds between the phenolic compounds as hydrogen bond donors (HBDs) and tertiary amines as hydrogen bond acceptors (HBAs), which was demonstrated by the spectroscopic detection. Interestingly, the HDES exhibits better CO2 -switchable behavior than traditional switchable-solvent, where the phase transition is induced by the protonation of HBA upon CO2and the deprotonation of HBD in HCO-3 solution of HBA. Furthermore, the sustainable separation for oils (heptane, diesel oil and crude oil) is successfully completed, and the HDES is also easily recovered upon N2/65°C. Finally, the HDES is effectively applied in removing petroleum hydrocarbons from oily wastes (oil sands and oily sludge). The results show that more than 98% oil is removed from oil sands, and 85.02% oil is also removed from oily sludge. Thus, the HDESs will be expected to treated as the effective extractant for sustainable and cleaner separation of petroleum hydrocarbons- contaminated waste.

In 2019,Journal of the American Chemical Society included an article by Mills, L. Reginald; Graham, Joshua M.; Patel, Purvish; Rousseaux, Sophie A. L.. Computed Properties of C7H8O2. The article was titled 《Ni-Catalyzed Reductive Cyanation of Aryl Halides and Phenol Derivatives via Transnitrilation》. The information in the text is summarized as follows:

Herein, Ni-catalyzed reductive coupling for the synthesis of benzonitriles from aryl(pseudo)halides and an electrophilic cyanating reagent, 2-methyl-2-Ph malononitrile (MPMN) is reported. MPMN is a bench-stable, carbon-bound electrophilic CN reagent that does not release cyanide under the reaction conditions. A variety of medicinally relevant benzonitriles can be made in good yields. Addition of NaBr to the reaction mixture allows for the use of more challenging aryl electrophiles such as aryl chlorides, tosylates, and triflates. Mechanistic investigations suggest that NaBr plays a role in facilitating oxidative addition with these substrates.

A new effective method for the construction of 1,4,2-benzodithiazine I (R = H, Cl); R1 = H, OMe; R2 = H, Cl, Me; R3 = H, Me, OMe; R2 R3 = -CH=CH-CH=CH-; and 1,2,3-benzoxathiazine II (R4 = H, OH, OMe; R5 = H, OMe) scaffolds, based on the use of easily accessible N-chlorosulfonyltrichloroacetimidoyl chloride, has been developed. Reactions of thiophenols 2-R-3-R1-4-R2-5-R3C6H1SH involved an initial nucleophilic substitution at the imine carbon atom with a thiol sulfur atom, followed by intramol. sulfonylation of the benzene ring. Phenols 3-R4-5-R5-C6H3OH exhibit opposite regioselectivity and react by electrophilic imidoylation of the ortho-carbon atom of the benzene ring (C-C bond formation) and sulfonation of the phenol oxygen atom.

Application of 150-19-6In 2021 ,《Exploring the Assembly of Resorc[4]arenes for the Construction of Supramolecular Nano-Aggregates》 appeared in International Journal of Molecular Sciences. The author of the article were Buonsenso, Fabio; Ghirga, Francesca; Romeo, Isabella; Siani, Gabriella; Pilato, Serena; Quaglio, Deborah; Pierini, Marco; Botta, Bruno; Calcaterra, Andrea. The article conveys some information:

Many biol. active compounds feature low solubility in aqueous media and, thus, poor bioavailability. The formation of the host-guest complex by using calixarene-based macrocycles (i.e., resorcinol-derived cyclic oligomers) with a good solubility profile can improve solubilization of hydrophobic drugs. Herein, we explore the ability of resorc[4]arenes to self-assemble in polar solutions, to form supramol. aggregates, and to promote water-solubility of an isoflavone endowed with anti-cancer activity, namely Glabrescione B (GlaB). Accordingly, we synthesized several architectures featuring a different pattern of substitution on the upper rim including functional groups able to undergo acid dissociation (i.e., carboxyl and hydroxyl groups). The aggregation phenomenon of the amphiphilic resorc[4]arenes has been investigated in a THF/water solution by UV-visible spectroscopy, at different pH values. Based on their ionization properties, we demonstrated that the supramol. assembly of resorc[4]arene-based systems can be modulated at given pH values, and thus promoting the solubility of GlaB. In addition to this study using m-Methoxyphenol, there are many other studies that have used m-Methoxyphenol(cas: 150-19-6Application of 150-19-6) was used in this study.

《Propylsulfonic acid grafted on mesoporous siliceous FDU-5 material: A high TOF catalyst for the synthesis of coumarins via Pechmann condensation》 was published in Microporous and Mesoporous Materials in 2020. These research results belong to Gonzalez-Carrillo, Gabino; Gonzalez, Jorge; Emparan-Legaspi, Maria Jose; Lino-Lopez, Gisela Jareth; Aguayo-Villarreal, Ismael A.; Ceballos-Magana, Silvia G.; Martinez-Martinez, Francisco J.; Muniz-Valencia, Roberto. Application In Synthesis of m-Methoxyphenol The article mentions the following:

In this sense, the use of propylsulfonic acid supported in FDU-5 (FDU-5-Pr-SO3H) as a catalyst for the synthesis of coumarins I (R1 = 7-OH, 5-Me-7-OH, 7,8-OH2, 7-OMe; R2 = Me, Ph) and 4-methyl-2H-benzo[h]chromen-2-one via Pechmann condensation in solvent-free medium was investigated. FDU-5-Pr-SO3H was synthesized by co-condensation of MPTES and TEOS. FDU-5-Pr-SO3H was used as catalyst for the synthesis of 7-hydroxy-4-methylcoumarin and their reaction conditions were optimized. The optimization process involved the study of the influence of the catalyst load, Resorcinol:EAA molar ratio, reaction temperature and reaction time. The optimal conditions were: catalyst load of 1.65 mol%, reactants molar ratio of 1:1.5, temperature 130°C and 60 min of reaction time. Under these conditions, the FDU-5-Pr-SO3H material showed excellent yield (96.5%) and turn over frequency (59 h-1). Finally, the synthesized material was assessed as a catalyst with other phenolic compounds and Et acetoacetate and with Et benzoylacetate. The obtained products were isolated and identified by comparison of their spectral data with those reported in literature; from these results, it can be concluded that the catalyst is active with a wide range of phenolic substrates. The experimental part of the paper was very detailed, including the reaction process of m-Methoxyphenol(cas: 150-19-6Application In Synthesis of m-Methoxyphenol)

《Online Liquid Chromatography-Raman Spectroscopy Using the Vertical Flow Method》 was written by Lo, Yu-Hao; Hiramatsu, Hirotsugu. Safety of m-Methoxyphenol And the article was included in Analytical Chemistry (Washington, DC, United States) in 2020. The article conveys some information:

Liquid chromatog. and Raman spectroscopy (LC-Raman system) were combined and developed with the aid of the vertical flow method that enhances the Raman signal intensity. The LC-Raman system enabled the online acquisition of the nonresonance Raman spectrum of LC eluates. The authors employed singular value decomposition (SVD) and subsequent reconstruction of the components for the anal. of 2-dimensional (temporal and spectral) data. The obtained components were consistent with the Raman spectra and elution patterns of the samples, indicating the appropriateness of the SVD-based procedure. The rise and fall times of the elution band of the temporal component were considered as the instrumental function. D2O mixed with H2O exhibited increased full width at half maximum of the elution band of up to 30% in comparison to the calculated value because of diffusion. Band broadening was less significant in the case in which an immiscible solute (pentane) was mixed with H2O. The limits of detection and quantitation were 1.2 ± 0.1, 2.1 ± 0.1, and 2.7 ± 0.1 mM and 4.1 ± 0.1, 6.9 ± 0.1, and 9.1 ± 0.2 mM for the ortho-, meta-, and para-isomers of methoxyphenol, resp. The nonresonance Raman experiment provides the mol. specificity to LC from the inherent properties of eluates.
