Extending the applications of Photoremovable Protecting Groups (PPGs) to cage phenols has generally met with unusually complex PPG byproducts. In this study, we demonstrate that thep-hydroxyphenacyl (pHP) cage for both simple and complex phenolics, including tyrosine, dispenses free phenols. With the simpler unsubstituted phenols, the reaction is governed by their Bronsted Leaving Group ability. On the other hand, the byproducts of the cage vary with these phenols. For the more acidic phenols the cage byproduct follows the Favorskii rearrangement to formp-hydroxyphenylacetic acid whereas for the weaker phenols other reactions such as reduction and hydrolysis begin to emerge. When the photolysis is conducted in octa acid (OA) containers, non-Favorskii, unrearranged fragments of the cage and other byproducts arise.

As a widely used chemical material, bisphenol A (BPA) is often used to produce kinds of chemicals, which lead risk to the ecological environment and human health. Based on the multi-catalysis of the nano-ZnO and multi-effect (chemical and physical) formed in the dielectric barrier discharge plasma (DBDP) system, the synergistic elimination of the BPA in the DBDP system combined with nano-ZnO was evaluated. The obtained experimental results showed that the superior adding amount of the nano-ZnO was 50 mg/L and the synergistic system on the condition had the best effect for the BPA degradation (85.4%), which was 17% higher than that in the sole DBDP system. When O-2 was bubbled into the reaction system, the degradation efficiency of the BPA in the synergistic system reached 100% after 20 min treatment. Compared with the alkaline solution, the acidic and weakly acidic solution could obtain higher treatment efficiency. (OH)-O-center dot and O-2(-) had a vital role for the BPA elimination in the synergistic system. The intermediate products detected by LC-MS included 4-cumylphenol, 4-isopropenylphenol, 4-tert-butylphenol, propiophenone, 1-(4-hydroxyphenyl) ethanone, tert-butylbenzene, benzoquinone and 1, 4-dihydroxybenzene.

Selective monoamine oxidase B inhibitors are potential drug candidates for the treatment of Parkinson’s disease. A series of phenyl substituted isoxazole carbohydrazides was designed by structural modification of isocarboxazid, a nonselective MAO inhibitor and evaluated as inhibitors of MAO-A and MAO-B. The compounds were not able to inhibit MAO-A significantly, but most of the compounds exhibited potent inhibitory activity against MAO-B. The enzyme kinetic study of the most active compounds 5d, 5-phenyl-N ‘-(1-(p-tolyl)ethylidene)isoxazole-3-carbohydrazide and 5g, N ‘-(1-(3,4-dimethoxyphenyl)ethylidene)-5-phenylisoxazole-3-carbohydrazide displayed reversible and competitive MAO-B inhibition. In molecular modeling studies, compounds 5d and 5g exhibited strong binding affinity on MAO-B active site. The administration of compounds 5d and 5g exhibited prevention of MPTP-induced Parkinsonism as indicated by footprint analysis and horizontal wire tests. Further optimization studies are essential to exploit their potential for MAO-B associated neurodegenerative pathologies.

A metal-free and photo-free method for the perfluoroalkylative pyridylation of alkenes has been developed via a combination of computational and experimental studies. Density functional theory calculations and control experiments indicate that the homolysis of R-f X (X 1/4 Br, I) bonds by the 4-cyanopyridine-boryl radicals in situ generated from 4-cyanopyridine and B(2)pin(2) is the key step. Sequential addition of Rf radicals to alkenes and the selective cross-coupling of the resulting alkyl radicals and 4-cyanopyridineboryl radicals gives alkene difunctionalization products with a quaternary carbon center. This method exhibits a broad substrate scope and good functional group compatibility.

Synthesis of amides via Beckmann rearrangement of ketoximes promoted by cyanuric chloride (TCT)/DMSO under mild conditions has been reported. Conditions of the Beckmann rearrangement, e.g., solvents, the ratios of TCT/DMSO, and the temperature, were investigated using diphenylmethanone oxime as a substrate. The optimized conditions were adopted to afford fourteen amides with yields ranging from 20% to 99%. A plausible mechanism involving an active dimethyl alkoxysulfonium intermediate was proposed according to the mass spectrometry analysis. To our best knowledge, this is the first case of study on Beckmann rearrangement of ketoximes promoted by TCT/DMSO under a mild condition to afford amides efficiently. (C) 2020 Elsevier Ltd.

Phenols from various man-made activities pose threats to public health and aquatic ecosystems. A number of technologies (e.g., adsorption, oxidation, and biological methods) have been proposed and tested to remove phenolic compounds from different sources. Among these technologies, oxidation process is considered one of the most efficient tools for abating phenolic compounds because of low cost, easy scalability, and ecofriendly production. In this work, we aim to synthesize and characterize potential catalysts (Co(II) and Cu(II) phthalocyanines 6 and 7) for phenolic compounds oxidation. Different parameters influenced the oxidation process were determined and phenolic compounds oxidize to the less harmful products with high conversion and yield in the presence of Co(II) and Cu(II) phthalocyanine catalysts.

The voltammetric oxidation of five para-substituted acetophenone derivatives (containing nitro, chloro, bromo, methyl and hydroxyl groups as substituents) and that of benzophenone was studied on a platinum and glassy carbon electrode in acetonitrile media. Electrode passivation was observed in the case when all selected compounds are on a glassy carbon electrode; an oxidation peak appeared between 2.5 and 3 V. The voltammograms of 4′-hydroxyacetophenone showed an additional peak around 2 V, which may be associated with the oxidation of the phenol moiety. In the case of a platinum electrode, no relevant peaks appeared on the voltammograms, reflecting the absence of passivation. The use of a redox probe 1,4-dihydroxybenzene showed that the glassy carbon electrode, after cyclization in the solutions of the outlined compounds, has higher sensitivity towards the oxidation product (1,4-benzoquinone) of this compound.

Ease of preparation of catalyst through simple solid-state exchange and its compatibility in producing excellent amount of O-allylated products and a plausible mechanistic pathway for the regioselectivity are highlighted. This reported procedure is not requiring any external stabilizing ligand for Cu(I) species and further purification of products.

Aggregation-induced emission luminogens (AlEgens) have attracted increasing attention in recent years on account of their attribute of overcoming the aggregation-caused quenching (ACQ) phenomenon of conventional organic fluorophores. Despite their remarkable advantages and great developments, most organic AlEgens exhibit broad emission spectra with the full width at half-maxima (FWHM) over 100 nm, which is to the disadvantage of their practical applications. Herein, supramolecular polymeric AIE materials with brighter fluorescence and narrower emission band (higher color purity) than conventional AlEgens were developed by taking advantage of the light-harvesting strategy. These AIE materials, including nanoparticles, microfibers, and thin films, were fabricated from supramolecular polymers comprising quadruple hydrogen-bonded monomer tetraphenylethylene (TPE) and borondipyrromethene (BODIPY) as antenna chromophores and as energy acceptors, respectively. The excitation energy collected by TPE molecules was efficiently transferred to the BODIPY, resulting in up to 6 fold enhanced fluorescence intensity and narrowed emission band with FWHM decreasing from 148 to 32 nm. The resulting nanoparticles showed similar to 5-fold higher brightness than commercial quantum dots. The highly fluorescent nanoparticles were successfully applied for in vitro and in vivo fluorescence and chemiluminescence imaging, showing superior imaging performance to conventional AIE nanoparticles.
