Quality Control of 1,4,7,10,13-PentaoxacyclopentadecaneIn 2019 ,《Effect of Copper Substrate Surface Orientation on the Reductive Functionalization of Graphene》 was published in Chemistry of Materials. The article was written by Zhang, Xu; Luo, Da; Zhang, Hanyang; Hwang, Dae Yeon; Park, Sung O.; Li, Bao-Wen; Biswal, Mandakini; Jiang, Yi; Huang, Yuan; Kwak, Sang Kyu; Bielawski, Christopher W.; Ruoff, Rodney S.. The article contains the following contents:

Although substrate composition can influence the chem. reactivity of graphene, substrate lattice orientation provides a valuable alternative. The effect of Cu surface orientation on the reactivity of graphene was explored through a reductive transformation. Among the substrates tested, only Cu(111) led to the efficient, fast and uniform functionalization of graphene, as demonstrated by Raman mapping, and this arose from compressive strain induced by Cu(111). Functionalization effectively relaxes the strain, which can be subsequently reintroduced after thermal treatment. Theor. calculations showed how compression facilitates the reduction and hybridization of carbon atoms, while coupling experiments revealed how kinetics may be used to control the reaction. The number of graphene layers and their stacking modes were also found to be important factors. In a broader context, a description of how graphene undergoes chem. modification when positioned on certain metal substrates is provided.1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Quality Control of 1,4,7,10,13-Pentaoxacyclopentadecane) was used in this study.

The title of the article was 《Mechanochemical synthesis of coumarins via Pechmann condensation under solvent-free conditions: an easy access to coumarins and annulated pyrano[2,3-f] and [3,2-f]indoles》.Safety of m-Methoxyphenol The author mentioned the following in the article:

A green protocol has been developed for the synthesis of simple coumarins, e.g., I linear pyrano[2,3-f] and [3,2-f]indoles by the reaction of phenol derivatives ROH (R = 3,5-(OH)2C6H3, 4-Br-3-OHC6H3, 3-OMeC6H4) with β-ketoesters, e.g., cyclohexanecarboxylic acid, 2-oxo-, Et ester under ball milling at ambient temperature in the presence of methanesulfonic acid as a mild acid catalyst. The significant advantages of this procedure are high yields, scalability, no use of hazardous acids or solvents, shorter reaction time, ambient temperature, low cost, and straightforward purification without column chromatog.

《Silver nanoparticles-decorated Preyssler functionalized cellulose biocomposite as a novel and efficient catalyst for the synthesis of 2-amino-4H-pyrans and spirochromenes》 was published in Scientific Reports in 2020. These research results belong to Saneinezhad, Sara; Mohammadi, Leila; Zadsirjan, Vahideh; Bamoharram, Fatemeh F.; Heravi, Majid M.. Category: ethers-buliding-blocks The article mentions the following:

Silver nanoparticles-decorated Preyssler functionalized cellulose biocomposite (PC/AgNPs) was prepared and fully characterized by FTIR, UV-vis, SEM, and TEM techniques. The preparation of PC/AgNPs was studied systematically to optimize the processing parameters by Taguchi method using the amount of PC, reaction temperature, concentration of silver nitrate and pH of medium. Taguchi’s L9 orthogonal (4 parameters, 4 level) was used for the exptl. design. The SEM anal. confirmed the presence of the Preyssler as a white cloud as well as spherical AgNPs on the surface of cellulose. The formation of AgNPs on the surface was observed by changing of the color from yellow to deep brown and confirmed by UV-vis spectroscopy. The best yield of AgNPs forming was obtained in pH 12.5 at 80°C in 20 min. TEM anal. confirmed the formation of spherical AgNPs with a size of 50 nm, at the 1% weight loading of Preyssler. This easily prepared PC/AgNPs was successfully employed as an efficient, green, and reusable catalyst in the synthesis of a wide range of 2-amino-4H-pyran I (R = Ph, 3-nitrophenyl, 4-chlorophenyl, etc.; X = CN, CO2Et), II (R1 = Ph, 2-methoxyphenyl, 4-chlorophenyl, etc.), III (R2 = Ph, 4-hydroxyphenyl, 4-chlorophenyl, etc.), IV (R3 = Ph, 2-nitrophenyl, 3-bromophenyl, etc.) and V and functionalized spirochromene derivatives via a one-pot, multicomponent reaction. The chief merits realized for this protocol were the utilization of com. available or easily accessible starting materials, operational simplicity, facile work-up procedure, obtaining of high to excellent yields of the products and being done under green conditions. The catalyst could be easily separated from the reaction mixture and reused several times without observing any appreciable loss in its efficiency. In the experiment, the researchers used many compounds, for example, 2-Methoxybenzaldehyde(cas: 135-02-4Category: ethers-buliding-blocks)

Its catalytic performance was assessed for the Suzuki coupling reaction; its synergetic effect and catalytic mechanism were also systematically investigated. Results showed that orientation, composition and distribution of catalyst had an efficient effect on catalytic activity.
