Polymer functionality greatly determines many of the key properties of these materials, such as glass-transition temperature, electrical and thermal conductivity, thermal stability, mechanical strength, and processability. Despite the importance of polymer functionality in determining material properties, the synthesis of functional polymers, with well-defined molecular weights and compositions, can still present a significant challenge, with many of the methods related to pre- or postpolymerization modification lacking synthetic scope, or requiring harsh functionalization conditions or transition-metal coupling reactions to install the desired functionality. Perfluoroaromatic systems are promising for the preparation of novel polymer architectures given that they can be readily functionalized using simple nucleophilic chemistries under very mild basic conditions. While promising, these systems have displayed some drawbacks. Previous work has shown that perfluoroaromatics, such as perfluoropyridine, can demonstrate a high degree of chemical reversibility with heteroatom nucleophiles. If the synthetic potential of these systems is to be realized, then a strategy for the rational design of stable monomers must be developed. Herein, we report the design, synthesis, and characterization of a series of unexplored heteroatom-based ring-opening metathesis polymerization (ROMP)-active monomers containing a reactive perfluoropyridine pendent group, which can be used to readily prepare a wide variety of aryl ether-functionalized polymers, using both pre- and postpolymerization modification strategies. We also establish a direct connection between the dihedral angle of the monomer and its propensity to undergo reversible addition reactions, establishing functional criteria for the design of pre- and postmodifiable systems.

The kinetics of the photoelectrochemical mineralization of p-nitrophenol (PNP) and p-methoxyphenol (PMP) on rutile:anatase TiO2 nanotube electrodes (% rutile: 0, 16, and 20) has been studied. Oxidative photocurrent enhances with the increase of both the electrode potential and the rutile content. Time-resolved photoluminescence measurements reveal that incorporation of rutile into anatase nanotubes has effects on recombination dynamics. From measurements of electrical charge as a function of time under thin-layer conditions under potentiostatic control, it was determined that the oxidation of PNP and PMP follows the apparent Langmuir-Hinshelwood rate law. Chemical oxygen demand measurements confirmed total oxidation. The reaction rate parameters that define the kinetic constant (k) due to the reaction of hydroxyl radicals with adsorbed phenols and the thermodynamic constant (K) due to the adsorption of phenols with the electrode surface have been decoupled. The interaction of PNP with the surface of all TiO2 electrodes is highly favored, K(PNP) > K(PMP), resulting in a surface concentration of PNP considerably higher than that of PMP. The specific rate of the surface reaction for the transformation of phenols also increases, but the trend is inverse, that is, for all electrodes, k(PMP) > k(PNP). Understanding these kinetic tendencies can lead to better transformation of light in redox reactions.

Application In Synthesis of Mequinol

Novel sulfonated carbon-coated magnetic nanoparticles (SCCMNPs; Fe3O4@C@OSO3H) were designed, synthesized, characterized, and applied as an efficient nanocatalyst for green synthesis of coumarin derivatives through Pechmann condensation. The Fe3O4@C@OSO3H was manufactured through a simple and inexpensive two-step procedure and characterized by FTIR, EDX, XRD, SEM, TEM, DLS, VSM, and TGA techniques. It was identified as an efficient heterogeneous catalyst in the Pechmann condensation of phenol derivatives and beta-ketoesters, leading to high-yield coumarin derivatives under solvent-free conditions. The Fe3O4@C@OSO3H removed after reaction finishing point by an external magnet, and it was reused fifteen times at the same conditions. Besides, theoretical studies were carried out using B3LYP/6-311++G(d,p) to more consideration of the reaction mechanism. The study of the frontier molecular orbitals, NBO atomic charges, molecular electrostatic potential of reactants, as well as Pechmann condensation mechanism was known very useful in suitable reactant choice. The reaction was performed through the electrophilic attack, dehydration, and trans-esterification, respectively. [GRAPHICS] .

The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5.

This study aimed to characterize the antioxidant potential, bioactive and volatile compounds of the stones from fruits of Cornus mas. Both fresh and roasted stones show a high antioxidant potential (166.48-509.74 mu mol TE/g dw stones), which significantly depends on the cultivars. The roasted stones preserved 43.6% (DPPH; ‘Raciborski’) to 97.2% (FRAP; ‘Alesha’) of the antioxidant activity of the non-roasted stones. In the stones, two iridoids and ellagic acid were determined. During roasting, loganic acid remained stable, whereas cornuside was completely degraded. The analyses showed a 30-fold increase in the concentration of ellagic acid and in the formation of two of its derivatives. The major aroma compound of the roasted stones was furfural, but we also identified 18 pyrazine derivatives. This study is the first attempt to valorize Cornelian cherry stones via roasting. The roasted stones can be a coffee substitute, or aromatic and bioactive additions to cereal coffees.

In order to gain new insights into the effect of the pi-pi stacking interaction of the indole ring with the Cu-II-phenoxyl radical as seen in the active form of galactose oxidase, we have prepared a Cu-II complex of a methoxy-substituted salen-type ligand, containing a pendent indole ring on the dinitrogen chelate backbone, and characterized its one-electron-oxidized forms. The X-ray crystal structures of the oxidized Cu-II complex exhibited the pi-pi stacking interaction of the indole ring mainly with one of the two phenolate moieties. The phenolate moiety in close contact with the indole moiety showed the characteristic phenoxyl radical structural features, indicating that the indole ring favors the pi-pi stacking interaction with the phenoxyl radical. The UV/Vis/NIR spectra of the oxidized Cu-II complex with the pendent indole ring was significantly different from those of the complex without the side-chain indole ring, and the absorption and CD spectra exhibited a solvent dependence, which is in line with the phenoxyl radical-indole stacking interaction in solution. The other physicochemical results and theoretical calculations strongly support that the indole ring, as an electron donor, stabilizes the phenoxyl radical by the pi-pi stacking interaction.

Oxidative Conversion of Sulfonyl Indoles into 3-Alkylidene-2-oxindoles under Flow Chemical Conditions

Sulfonyl indoles were converted into 3-alkylidene-2-oxindoles using NCS as the sole reagent under flow chemical conditions. The conjugated oxindole derivatives were generally obtained as E stereoisomers in moderate to satisfactory yields. The transformation entails the oxidation of the indole ring by NCS followed by elimination of arylsulfinic acid in order to install the exocyclic unsaturation.
