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 floral fragrance of plants is an important indicator in their evaluation. The aroma of sweet cherry flowers is mainly derived from their essential oil. In this study, based on the results of a single-factor experiment, a Box-Behnken design was adopted for ultrasound- and microwave-assisted extraction of essential oil from sweet cherry flowers of the Brooks cultivar. With the objective of extracting the maximum essential oil yield (w/w), the optimal extraction process conditions were a liquid-solid ratio of 52 mL g(-1), an extraction time of 27 min, and a microwave power of 435 W. The essential oil yield was 1.23%, which was close to the theoretical prediction. The volatile organic compounds (VOCs) of the sweet cherry flowers of four cultivars (Brooks, Black Pearl, Tieton and Summit) were identified via headspace solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS). The results showed that a total of 155 VOCs were identified and classified in the essential oil from sweet cherry flowers of four cultivars, 65 of which were shared among the cultivars. The highest contents of VOCs were aldehydes, alcohols, ketones and esters. Ethanol, linalool, lilac alcohol, acetaldehyde, (E)-2-hexenal, benzaldehyde and dimethyl sulfide were the major volatiles, which were mainly responsible for the characteristic aroma of sweet cherry flowers. It was concluded that the VOCs of sweet cherry flowers were qualitatively similar; however, relative content differences were observed in the four cultivars. This study provides a theoretical basis for the metabolism and regulation of the VOCs of sweet cherry flowers.

We report a new strategy for the conversion of carboxylic acids into potent acid triflate electrophiles. The reaction involves oxidative carbonylation of carboxylic acids with I-2 in the presence of AgOTf, and is postulated to proceed via acyl hypoiodites that react with CO to form acid triflates. Coupling this chemistry with subsequent trapping with arenes offers a mild, room temperature approach to generate ketones directly from broadly available carboxylic acids without the use of corrosive and reactive Lewis or Bronsted acid additives, and instead from compounds that are readily available, stable, and functional group compatible.

An efficient method for the synthesis of a new highly substituted pyrrolidinone derivative is developed via a three-component one-pot reaction of aniline, diethyl acetylenedicarboxylate, and 4-anisaldehyde. The structure of ethyl 4-hydroxy-2-(4-methoxyphenyl)-5-oxo-1-phenyl-2,5-dihydro-1H-pyrrole-3-carboxylate is confirmed by FTIR, H-1 and C-13 NMR spectroscopy. Unambiguous evidence for the structure of the synthesized product is obtained from the single crystal X-ray analysis. The comparison of both its molecular structure and intermolecular interactions with the previously known analogous compounds reveals that the mutual syn- or antiperiplanar orientation of ester C=O and pyrrolinone-bound OH is related to the type of molecular dimers formed in the solid state. The geometrical structure, the HOMO-LUMO analysis (electrophilicity index), H-1 and C-13 chemical shifts of the desired product are also calculated by DFT at the B3LYP level with the 6-31++G(d,p) basis set. The calculated chemical shifts are in compliance with the experimental data.

Binary organocatalytic ring-opening polymerization (ROP) of N-Boc-1,4-oxazepan-7-one (OxP(BOC)) is proposed as a versatile method to generate metal-free poly(amine-co-ester)s and the corresponding biodegradable polycationic homo/block (co)polymers. Optimization experiments with different organocatalysts, including 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD), DBU/1-(3,5-bis(trifluoromethyl)phenyl)-3-cyclohexylthiourea (TU1), and phosphazene/thiourea, revealed that t-Bu-P-4/TU1 leads to a fast and controlled/living ROP with benzyl alcohol (BnOH) as an initiator and thus allows the formation of well-defined poly(amine-co-ester)s with high molecular mass (M-n,M-SEC up to 38.8 kg mol(-1)) and narrow dispersity. Well-defined poly(N-Boc-1,4-oxazepan-7-one)-based diblock copolymers were also synthesized successfully via the controlled/living ROP, regardless of whether hydrophilic poly(ethylene glycol) (PEG) or hydrophobic polycaprolactone (PCL) was used as a macroinitiator. After treatment with trifluoroacetic acid, the corresponding water-soluble polycationic homopolymer, as well as the hydrophilic (PEG -based copolymer) and amphiphilic (PCL-based copolymer) polycationic diblock copolymers, was obtained. Dynamic light scattering in water and transmission electron microscopy analyses revealed that both polycationic copolymers self-assembled spontaneously to nanostructures; the hydrophilic block copolymer formed spherical nanoparticles, while the amphiphilic one formed rod-shaped nanoparticles.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Silver and palladium nanoparticles anchored to the core-shell Fe3O4@SiO2@Al2O3 were successfully synthesized based on MIL(Al)96 MOF. The nanocomposites, 15-20 nm in size, exhibited high catalytic activity for selective aerobic oxidation of alcohols (even aliphatic alcohols) to the corresponding carbonyl compounds at room temperature without addition of any other additives. In this regard, the Fe3O4@SiO2@Al2O3/Pd,Ag exhibited more catalytic activity than the others. The cytotoxic effect of nanocomposites was tested in-vitro against MCF-7 human breast cancer cells by MTT assay. The results showed that all synthesized nanocomposites will be promising and potential as anticancer agents, with sample Fe3O4@SiO2@Al2O3 being the most cytotoxic after 24 and 48 h. Also, the obtained nanocomposites could induce apoptosis in breast cancer cell line (MCF-7) and the ability of induce apoptosis was in the following order: Fe3O4@SiO2@Al2O3@Ag > Fe3O4@SiO2@Al2O3 > Fe3O4@SiO2@Al2O3@Pd,Ag > Fe3O4@SiO2@Al2O3@Pd.

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.

In this report, SO3H-functionalized Carbon nanoparticles (Pine-SO3H) with high acid density have been synthesized by the thermal treatment of sulfuric acid with Pine-Cone as carbon-based at 180 degrees C in a sealed autoclave in a one-step procedure. The resulted Nanocatalyst was characterized by FT-IR, TGA, XRD, FE-SEM and elemental analysis (EA). The result of characterization was shown that the carbon-based acid is amorphous with polycyclic aromatic carbon sheets attached plentiful -OH, -COOH, and -SO3H groups. The catalytic activities of Pine-SO3H was investigated in the highly efficient synthesis of pyrano[2,3-c] pyrazole, amino-benzochromenes, amidoalkyl naphthol and 5-arylidene-2,4-thiazolidinedione derivatives. The application of Pine-SO3H in the synthesis offers several advantages such as simple procedure with an easy work-up, recoverable catalyst, mild condition, eco-friendliness, excellent yields, short reaction times and use of an inexpensive catalyst.

The present study investigated the degradation of bisphenol A (BPA) from aqueous solution using Fe3O4/persulfate process. The effects of pH (3, 5, 7 and 11), persulfate (PS) concentrations (1, 2, 5 and 10 mM), Fe3O4 magnetic nanoparticle doses (0.5, 1, 1.5 and 2 g/L), and contact time (5, 10, 20 and 30 min) on BPA removal were examined. The effect of all factors was significant (p < 0.05), and the optimal conditions were: pH value of 3, Fe3O4 dose of 2 g/L, BPA concentration of 0.1 mg/L, and contact time of 30 min. The BPA removal efficiency under optimal conditions was 98%. The results of this work indicate that Fe3O4 nanoparticles can be used as an effective catalyst and adsorbent for the removal of BPA from water and industrial wastewater. Analysis of by-products of BPA using GC-MS detected the presence of compounds with lower molecular weights (4-hydroxyacetophenone, 4-isopropenylphenol, benzoquinone and succinic acid) relative to BPA.

A highly efficient Ni/N-C catalyst was synthesized by facile pyrolysis of a Ni-containing metal-organic framework (Ni-MOF), and its catalytic hydrogenolysis performance towards C-O bonds in lignin was evaluated in detail using diphenyl ether (DPE) as a model compound. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses show that the flower-like nanosheets of the Ni-MOF shrink, forming a loose and ordered spherical structure during pyrolysis. Under the optimal conditions, DPE was completely converted and the selectivity to monomers (benzene, cyclohexanol and cyclohexane) reached 99.1%. During the catalytic hydrogenolysis conversion (CHC) of DPE, the direct cleavage of the C-aromatic-O bond affording benzene and phenol is the major reaction pathway, and a low H2 pressure is crucial to increase the monomer selectivity. Furthermore, Ni/N-C-450 shows high hydrogenolysis activity for other lignin-derived aryl ethers, such as benzyl phenyl ether, dibenzyl ether, dinaphthalene ether, benzyl 2-naphthyl ether and 3-methoxyphenol.
