Now introduce a scientific discovery about this category.

The obtained spiroindolinebenzopyrans bearing benzoxazole fragment in the position 8 of the benzopyran part appear as polychromogenic molecular systems exhibiting not only photochromic but also ionochromic properties. Photochromic properties demonstrate variability of spectral kinetic characteristics in the wide range depending on structural features and a solvent nature. Efficiency of photocoloration process is more than one order of magnitude higher than the photobleaching quantum yield. Owing to the presence of a benzoxazole fragment ionochromic properties allow detecting presence of such metal cations as Co2+, Ni2+, Zn2+,Cu2+, Cd2+. Exemplified by Ni2+, Zn2+ ionochromic effect has been quantitatively described. Combination of photochromism and ionochromism in the obtained spiropyrans afford an opportunity to create metal ion chemosensor with photodriven recognition function.

Environmental remediation through the recycling and upcycling of waste plastics is an urgent global concern. Accordingly, we herein demonstrate the organocatalyzed depolymerization of poly(ethylene terephthalate) (PET) with o-phenylenediamine (OPD) and 2-aminophenol (2AP) to form bis-benzimidazole and bis-benzoxazole, which can potentially be applied to the production of medicines, high-performance polymers, and organic electronics. Although high-temperature treatment at 190 degrees C was required, the neutral superbase 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) successfully facilitated two nucleophilic substitution reactions in one-pot, i.e., amidation or transesterification of PET followed by heterocycle formation to the amide or ester group. Theoretical studies with B3LYP density functional theory were performed for model reactions using methyl benzoate (MB) and OPD or 2AP. Consequently, we revealed that amidation favorably proceeds in the first depolymerization step and that the heterocycle formation predominantly results from nucleophilic attack to the amide intermediate by the anilinic NH2 or phenolic OH with the assistance of TBD. We also found that multiple hydrogen-bonding activations involving the bifunctional nature of TBD and the bidentate interactions of nucleophilic reagents such as OPD and 2AP with carbonyl oxygen atoms enable the one-pot formation of benzimidazoles and benzoxazoles from PET. Thus, this study not only demonstrates a new valuable method for upcycling of PET, but also offers a new synthetic route to benzimidazoles and benzoxazoles.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 148893-10-1.

Ultrasonic-Assisted Ionic Liquid Extraction of Two Biflavonoids from Selaginella tamariscina

Selaginella tamariscina, a traditional Chinese medicine, contains a variety of bioactive components, among which biflavonoids are the main active ingredients and have antioxidant, antitumor, and anti-inflammatory properties. In this study, ultrasonic-assisted ionic liquid extraction (UAILE) is used for the first time to extract two main biflavonoids (amentoflavone (AME) and hinokiflavone (HIN)) from S. tamariscina. A high-performance liquid chromatography method is used for the simultaneous determination of AME and HIN in S. tamariscina. Then, three novel ILs are synthesized for the first time by a one-step method using benzoxazole and three acids or acid salts as raw materials, and the structures of the synthesized ILs are characterized by elemental analysis, infrared spectroscopy, and NMR spectroscopy, as well as the thermal stability of the ILs is evaluated by thermogravimetric analysis. After screening the extraction effects of three benzoxazole ILs, three pyridine ILs, and three imidazole ILs, it is found that [Bpy]BF 4 is the best and therefore selected as the extractant. The optimal extraction process is explored in terms of the yields of AME and HIN from S. tamariscina by a single-factor experiments and response surface analysis. Under the optimal level of each influencing factor (IL concentration of 0.15 mol/L, solid-liquid ratio of 1:12 g/mL, ultrasonic power of 280 W, ultrasonic time of 30 min, and three extraction cycles), the extraction rates of AME and HIN from S. tamariscina are 13.51 and 6.74 mg/g, respectively. Moreover, the recovery experiment of [Bpy]BF 4 on the extraction of biflavonoids shows that the recovered IL can repeatedly extract targets six times and the extraction rate is about 90%, which indicates that the IL can be effectively reused. UAILE can effectively and selectively extract AME and HIN, laying the foundation for the application of S. tamariscina.

Oxidation of sulfides including DBT using a new vanadyl complex of a non-innocent o-aminophenol benzoxazole based ligand

Reaction of a non-innocent o-aminophenol benzoxazole based ligand HLBAP with VOCl3 afforded a vanadyl complex, VOLBIS (SQ), in which SQ is a 2,4-di-tert-butylsemiquinone produced from hydrolysis of HLBAP. The crystal structure of VOLBIS (SQ) exhibits an octahedral geometry with the VO2+ center coordinated by two nitrogen and one oxygen atoms of L-BAP and two oxygen atoms of SQ. Electrochemical studies showed quasi-reversible metal-centered reduction and ligand-centered oxidation of complex. The magnetic moment of VOLBIS (SQ) is consistent with the spin-only value expected for S = 1/2 system. The neutral species of VOLBIS (SQ) is EPR active, which is consistent with a paramagnetic electronic ground state (S = 1/2). This result is in accordance with the vanadyl (IV) moiety surrounded by tridentate iminobenzosemiquinonate anion radical (HLBIS)(center dot-) and benzosemiquinone ligand (SQ)(center dot). The theoretical calculations confirm the experimental results. Furthermore, we present the optimal conditions for maximum efficiency of sulfide oxidation for oxidative desulfurization with hydrogen peroxide and 6 times reusability of catalyst for sulfoxidation of dibenzothiophene.

Molecularly imprinted covalent organic polymers for the selective extraction of benzoxazole fluorescent whitening agents from food samples

Molecularly imprinted covalent organic polymers were constructed by an imine-linking reaction between 1,3,5-triformylphloroglucinol and 2,6-diaminopyridine and used for the selective solid-phase extraction of benzoxazole fluorescent whitening agents from food samples. Binding experiments showed that imprinting sites on molecularly imprinted polymers had higher selectivity for targets compared with those of the corresponding non-imprinted polymers. Parameters affecting the solid-phase extraction procedure were examined. Under optimal conditions, actual samples were treated and the eluent was analyzed with high-performance liquid chromatography with diode-array detection. The results showed that the established method has a wide linearity, satisfactory detection limits and quantification limits, and acceptable recoveries. Thus, this developed method possesses the practical potential for the selective determination of benzoxazole fluorescent whitening agents in complex food samples.

Synthesis and Antimicrobial Activity of 2-Trifluoroacetonylbenzoxazole Ligands and Their Metal Complexes

Three 2-fluoroacetonylbenzoxazole ligands 1a-c and their new Zn(II) complexes 2a-c have been synthesized. In addition, syntheses of new metal [Mg(II), Ni(II), Cu(II), Pd(II), and Ag(I)] complexes from la have been also described. The molecular and crystal structures of six metal complexes 2b and 2d-h were determined by single-crystal X-ray diffraction analyses. Their antibacterial activities against six Gram-positive and six Gram-negative bacteria were evaluated by minimum inhibitory concentrations (MIC), which were compared with those of appropriate antibiotics and silver nitrate. The results indicate that some metal compounds have more antibacterial effects in comparison with free ligands and have preferred antibacterial activities that may have potential pharmaceutical applications. Noticeably, the Ag(I) complex 2h exhibited low MIC value of 0.7 mu m against Pseudomonas aeruginosa, which was even superior to the reference drug, Norfloxacin with that of 1.5 mu m. Against P. aeruginosa, 2h is bacteriostatic, exerts the cell surface damage observed by scanning electron microscopy (SEM) and is less likely to develop resistance. The new 2h has been found to display effective antimicrobial activity against a series of bacteria.
