We report on the shape, composition (from Pt95Zn5 to Pt77Zn23), and surface chemistry of Pt-Zn nanoparticles obtained by reduction of precursors M2+(acac) (-)(2) (M2+: Pt2+ and Zn2+) in oleylamine, which serves as both solvent and ligand. We show first that the addition of phenyl ether or benzyl ether determines the composition and shape of the nanoparticles, which point to an adsorbate-controlled synthesis. The organic (ligand)/inorganic (nanoparticles) interface is characterized on the structural and chemical level. We observe that the particles, after washing with ethanol, are coated with oleylamine and the oxidation products of the latter, namely, an aldimine and a nitrile. After exposure to air, the particles oxidize, covering themselves with a few monolayer thick ZnO film, which is certainly discontinuous when the particles are low in zinc. Pt-Zn particles are unstable and prone to losing Zn. We have strong indications that the driving force is the preferential oxidation of the less noble metal. Finally, we show that adsorption of CO on the surface of nanoparticles modifies the oxidation state of amine ligands and attribute it to the displacement of hydrogen adsorbed on Pt. All the structural and chemical information provided by the combination of electron microscopy and X-ray photoelectron spectroscopy allows us to give a fairly accurate picture of the surface of nanoparticles and to better understand why Pt-Zn alloys are efficient in certain electrocatalytic reactions such as the oxidation of methanol.

We report on a detailed multi-spectroscopic analysis of the structures and internal dynamics of diphenylether and its aggregates with up to three water molecules by employing molecular beam experiments. The application of stimulated Raman/UV and IR/UV double resonance methods as well as chirped-pulse Fourier transform microwave spectroscopy in combination with quantum-chemical computations yield the energetically preferred monomer and cluster geometries. Furthermore, the complex internal dynamics of the diphenylether monomer and the one-water clusters are analysed. In the cluster with three water molecules, water forms a cyclic structure similar to the isolated water trimer. The interactions ruling the structures of the higher-order water clusters are a combination of the ones identified for the two monohydrate isomers, with dispersion being a decisive contribution for systems that have a delicate energetic balance between different hydrogen-bonded arrangements of similar energy.

Hydroformylation remains the most applied industrial process to produce aldehydes. Much research has been devoted to developing new catalyst systems since aldehydes are highly desired. Supported metal catalyst complexes have drawn renewed attention due to an increased interest in benign and environmental processes. In this paper, NiXantphos has been immobilized on hyperbranched poly(arylene oxindole) supports, different in linker, via a one-step postfunctionalization. Two heterogeneous hyperbranched poly(arylene oxindole) supported NiXantphos ligands were evaluated in the microwave-assisted rhodium-catalyzed hydroformylation of olefins. After selection of the best reaction conditions, a variety of functionalized olefins were successfully converted into the desired linear aldehydes working under milder conditions compared to known processes, in terms of syngas pressure (4.8 bar), temperature (75 degrees C), and reaction times (20 min). The increased activity might emanate from a positive dendritic effect unique to the dendritic nature of the support. Furthermore, the catalyst system was successfully recovered and reused without a decrease in activity or regioselectivity, thus demonstrating to be a valid alternative to classical homogeneous procedures.

A variety of physicochemical properties and several hydrogenbond donors have been used to define methods and to build scales aiming at measuring the hydrogen-bond acceptance of solvents. There is a great deal of confusion in these scales and methods. Solvatochromic, solvatocalorimetric, solvatovibrational, and F-19 solvatomagnetic comparison methods are critically reviewed. Only two methods, the solvatomagnetic and the solvatocalorimetric ones, are able to yield reliable solvent hydrogen-bond acceptance scales. The solvatomagnetic beta(1) scale defined from the F-19 chemical shift of 4-fluorophenol is extended to many solvents including ionic liquids and green solvents. The results for about 240 hydrogen-bond acceptor solvents are organized in a numerical beta(1) database. The comparison of beta(1) with solvatochromic scales highlights their shortcomings, in particular for the important class of amphiprotic solvents. Therefore, the use of the F-19 solvatomagnetic comparison method and of the solvatomagnetic beta(1) scale is recommended in solvent effect studies.

One inhibitor of the fatty acid transporter FATP4 was synthesized in a three steps one-pot process in the presence of a bifunctional metal/acid catalyst. This molecule which has potential interest for the treatment of the obesity in orlistat (Xenical(TM)) analogue-based therapies has a 3,4-dihydropyrimidin-2(1H)-one (DHPM) scaffold and was obtained by means of a three one-pot process through successive oxidation, cyclocondensation and transesterification reactions. The one-pot strategy was extended to the synthesis of a series of related ester DHPM derivatives.

Constitutive androstane receptor (CAR) activation has found to ameliorate diabetes in animal models. However, no CAR agonists are available clinically. Therefore, a safe and effective CAR activator would be an alternative option. In this study, sixty courmarin derivatives either synthesized or purified from Artemisia capillaris were screened for CAR activation activity. Chemical modifications were on position 5,6,7,8 with mono-, di-, tri-, or tetra-substitutions. Among all the compounds subjected for in vitro CAR activation screening, 6,7-diprenoxycoumarin was the most effective and was selected for further preclinical studies. Chemical modification on the 6 position and unsaturated chains were generally beneficial. Electron-withdrawn groups as well as long unsaturated chains were hazardous to the activity. Mechanism of action studies showed that CAR activation of 6,7-diprenoxycoumarin might be through the inhibition of EGFR signaling and upregulating PP2Ac methylation. To sum up, modification mimicking natural occurring coumarins shed light on CAR studies and the established screening system provides a rapid method for the discovery and development of CAR activators. In addition, one CAR activator, scoparone, did showed anti-diabetes effect in db/db mice without elevation of insulin levels.

The comprehensive identification of organic species existing in indoor environments is a key issue to understand their impact in human health. This study proposes the analysis of condensed water samples, collected with portable dehumidifiers, to characterize semi-volatile compounds in the gas phase of confined areas. Water samples are concentrated by solid-phase extraction (SPE). The obtained extracts are analysed by gas chromatography (GC) time-of-flight mass spectrometry (TOF-MS), following a nontarget screening data mining approach. In first term, spectra of deconvoluted compounds are compared with those in NIST low resolution library; thereafter, tentative identifications are verified using an inhouse database of accurate electron ionization (EI) MS spectra. Chromatographic (retention index) and spectral data are combined for unambiguous species identification. The potential of condensed water samples to reflect changes in the composition of indoor atmospheres, the match between data obtained using different dehumidifiers, and the relative concentration efficiency of condensed water compared to that attained by active sampling of moderate air volumes are discussed. A total of 141 semi-volatile compounds were identified (98 confirmed against authentic standards) in a set of 21 samples obtained from different homes and working places. This list contains more than 40 fragrances (including several potential allergens), solvents and intermediates in the production of polymeric materials, plasticizers and flame retardants.

Lignin is constructed from methoxylated phenylpropanoid with plenty of hydroxys and methoxys. Its conversion to valuable products is extremely attractive but especially challenging without additional hydrogen sources. Herein we report a hydrogen-free production of 4-alkylphenols directly from native lignin via self-reforming-driven depolymerization and hydrogenolysis over Pt/NiAl2O4. This is the first example of acquiring 4-alkylphenols from native lignin. Using this strategy, high yields of 4-alkylphenols, 17.3 wt %, were obtained from birch lignin. Reaction pathway and mechanism studies revealed that this strategy initiates from the reforming of aliphatic hydroxys, followed by the cleavage of C-O linkages, and ends via demethoxylation over Pt/NiAl2O4. Moreover, the subsequent aqueous phase reforming of the as-formed methanol accelerates the whole process. This strategy realizes the one-pot production of 4-alkylphenols from lignin by fully utilizing the structural hydrogen in lignin and H2O, providing a low-cost and safe method of lignin valorization.

Methyl and phenyl esters of 2 ‘,3 ‘-PhABA and iso-2 ‘,3 ‘-PhABA were prepared for the biological investigation and development of practical applications. These esters exhibited excellent activity in most plant growth inhibitory assays. And, three esters were more efficient than ABA in stomatal closure. The 2 ‘,3 ‘-PhABA analogs and their methyl esters have good stability in hydrolysis assay, and the different lipid solubility and permeability of different esters may be one of the origins of their active selectivity for different plants and physiological processes. Furthermore, in the study of drought tolerance, all four esters had comparable activity to ABA. These results suggest that these esters were potent plant growth regulator (PGR) candidates for anti-drought. The finding that different esters have different selective bioactivity and biophysical properties indicates that these esters not only function as ABA-like PGRs but also have the possibility as potential selective pro-hormone. Graphical abstract 2, 3’- BenzoABA esters as PGR candidates with prolonged and selective bioactivity. [GRAPHICS] .
