The article was titled 《Phenanthroline derivative fluorescent probe for rapid and sensitive detection of silver(I)》, and you may find the article in Analytical Sciences.Quality Control of 2-Methoxybenzaldehyde The information in the text is summarized as follows:

In the present work, a phenanthroline derivative (2-(2-methoxyphenyl)-4-phenyl-1,10-phenanthroline, MPP), as a fluorescent probe, was synthesized to realize a rapid, simple and sensitive detection of silver(I). The detection conditions of Ag+ were optimized. This fluorescent probe has the advantages of a fast reaction time, a wide pH applicable range, and a low detection limit, exhibiting a good linear response between the fluorescence intensity and the concentration in the range of 0.05 – 1.5 μmol/L for Ag+. The detection limit is as low as 3.38 x 10-8 mol/L (S/N = 3). This probe had been used to detect Ag+ in real samples, and the recovery efficiency of spiked Ag+ had been also tested. The recovery efficiency is satisfactory, ranging from 92.0 to 105.4%. Therefore, this fluorescent probe should provide a new choice for the quant. detection of silver ions in environmental water samples.

The article was titled 《Enantioselective Au(I)-Catalyzed Multicomponent Annulations via Tethered Counterion-Directed Catalysis》, and you may find the article in ACS Catalysis.Category: ethers-buliding-blocks The information in the text is summarized as follows:

Gold(I) complexes of a chiral phosphoric acid-functionalized phosphine of the CPA-Phos series enable the enantioselective multicomponent reactions between aldehydes, hydroxylamines, and cyclic yne-enones, leading to 3,4-dihydro-1H-furo[3,4-d][1,2]oxazines. This represents a rare example of a highly enantioselective multicomponent reaction in gold(I) catalysis. The reactions proceed at a low catalyst loading and provide high yields, total diastereoselectivity, and enantiomeric excesses up to 99%. Silver-free conditions was applied. The method had a very broad scope as it applies to both aliphatic and aromatic aldehydes and hydroxylamines, to a variety of cyclic yne-enones, and to yne-enone-derived oximes.

In 2022,Wu, Kai; Yang, Ke; Wang, Siyu; Yu, Jiajun; Chu, Chenyang; Luo, Bingbing; Zhang, Huiyan published an article in Bioresource Technology. The title of the article was 《The enrichment of sugars and phenols from fast pyrolysis of bamboo via ethanol-Fenton pretreatment》.Quality Control of m-Methoxyphenol The author mentioned the following in the article:

The high-purity compounds (e.g., sugars and phenols) are important raw materials and chems., which can be produced by biomass pyrolysis. However, the direct biomass pyrolysis produces complex compounds and thus inhibiting its large-scale utilization. To increase the yield and enrichment of sugars and phenols, a green coupling process based on ethanol-Fenton pretreatment combined with fast pyrolysis is firstly proposed. The bamboo was effectively separated into the ethanol-Fenton pretreated bamboo (EF-bamboo), lignin-rich fractions, and hemicellulose-degradation intermixts. with the massive removal of inorganic metals via this process. Compared with the fast pyrolysis of raw bamboo, the levoglucosan yield of EF-bamboo increased 5.4 times and the enrichment of sugars improved from 7.6% to 59.7%. Similarly, the yield of monophenols from lignin-rich fractions increased around 0.6 times and the enrichment of monophenols increased from 25.7% to 63.5%. This work provides a green and efficient route to produce high-yield and high-enrichment sugars and phenols.

In 2022,Hu, Zhitao; Cao, Xiaohui; Zhang, Xiaohui; Wu, Bin; Luo, Wenjun; Huang, Huahua; Li, Le; Chen, Yongming published an article in ACS Macro Letters. The title of the article was 《Catalytically Controlled Ring-Opening Polymerization of 2-Oxo-15-crown-5 for Degradable and Recyclable PEG-Like Polyesters》.Computed Properties of C10H20O5 The author mentioned the following in the article:

Poly(ethylene glycol) (PEG) has been extensively used in diverse applications. However, it is not biodegradable and shows abnormal immune responses. Herein, a fast, controlled, ring-opening polymerization (ROP) of 2-oxo-15-crown-5 (O-15C5) is reported to prepare well-defined PEG-like polyesters, poly(O-15C5). This approach relies on a coordination between the macrocyclic monomer and Na+ that increases the electrophilicity of the carbonyl group of O-15C5 and leads to a fast controlled ROP (dispersity, DM < 1.2). Both computational and mechanistic studies show that the selective Na+ binding to the monomer over poly(O-15C5) allows the ring-opening initiation and propagation to be more energetically favorable than side transesterifications. This is the key to control the challenging entropy-driven ROP of O-15C5. Moreover, with the aid of Na+ and organic base, poly(O-15C5) depolymerized readily into O-15C5 in 2 h. Also, it degraded in a buffer of pH 7.4 by hydrolysis. After reading the article, we found that the author used 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Computed Properties of C10H20O5)

1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations.
