The development of new fluorine-containing building blocks and their efficient synthetic access is currently a challenging research field. Herein, the highly regio- and stereoselective addition of a large range of aldehydes onto trifluoromethylated benzofulvenes was achieved using a simple La/I-2/DIBAL-Cl system via a selective C-F bond activation process. This versatile methodology provided homodienyl alcohols bearing a terminal CF2-alkene with potential further applications, as shown by the dehydration to the first benzofulvenes carrying a difluorovinyl group. In addition, for certain electron-poor aldehydes, unprecedented ipso substitution of the CF3 group in a diene was observed, which, according to DFT studies, is related to the presence of the large, Lewis-acidic lanthanum metal.

This research demonstrated the development of graphene oxide (GO)-gold nanocrystals (AuNCs) compositemodified glassy carbon electrode (GCE) for the sensitive detection of dopamine (DA), uric acid (UA), and 4-aminophenol (4-AP). The GO was synthesized by modified Hummer’s method, which was utilized to prepare GO-AuNCs composites by in situ synthesis method using sodium L(-) malate as a reducing agent. Morphological, X-ray diffraction, and spectral analysis revealed the homogeneous formation of AuNCs with high crystallinity and purity on the GO surface and the sizes of the NCs were decreased with increasing the concentrations of sodium L (-) malate. The optimal GCE/GO-AuNCs sensor exhibited excellent electrocatalytic activity towards the oxidation of DA, UA, and 4-AP. The sensor showed interference-free and selective detection of DA and UA with sensitivities of ca. 30.3 and 17.28 mu A/cm(2)/mu M, respectively, and detection limits of ca. 28 and 50 nM, respectively, with wider dynamic ranges, measured by differential pulse voltammetry (DPV) technique. Whereas, it displayed a sensitivity and detection limit of ca. 5.70 mu A/cm(2)/mu M and 0.017 nM, respectively, for the detection of 4-AP, using current density (J)-voltage (V) measurement method. The sensor also revealed excellent stability, reproducibility, and recoveries of DA, UA, and 4-AP in real samples.

Objective: To characterize the epidemiology of unintentional asphyxias in Mexico from 1999 to 2017. Method: Secondary analysis of vital registries, three national health surveys and information from the safety inspection program of the Ministry of Health in Mexico were used to characterize fatal and non-fatal drownings (ICD-10: W65-W74) and other asphyxias including suffocation, chocking and strangulation (ICD-10: W75-W84), and to estimate the level of exposure to different risk factors within households and daycares. Results: 100,834 deaths were registered, 44.66% were drowning and 77.17% male. Drown ngs mainly affect children and adolescents, occur in April, July and August, on Sundays, during the afternoon. Other asphyxias affect children and the elderly more frequently, occur mainly from December to February, on Sundays and from 4 to 6h. According to ENSANut-2012, 53,065 individuals experience a non-fatal asphyxia per year, 26.21% of them with permanent consequences in their health and wellbeing. Important risks of unintentional asphyxias are present in 38% of daycares and 80% of households analyzed. Conclusions: Unintentional asphyxias are a major public health problem that needs to be urgently attended to achieve the Sustainable Development Goals, in particular the 3.2. Evidence presented in this work constitutes an input to inform and orient efforts directed to tackle this problem. (C) 2019 SESPAS. Published by Elsevier Espana, S.L.U.

A metal- and additive-free methodology for the highly selective, photocatalyzed C-H oxygenation of alkylarenes under air to the corresponding carbonyls is presented. The process is catalyzed by an imide-acridinium that forms an extremely strong photooxidant upon visible light irradiation, which is able to activate inert alkylarenes such as toluene. Hence, this is an easy to perform, sustainable and environmentally friendly oxidation that provides valuable carbonyls from abundant, readily available compounds.

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

The effect of introducing a lateral methyl substituent and the two different alkoxy terminal groups on the mesophase behavior of three-benzene-ring molecular core of azo-ester compounds bearing 2-methylbutoxy unit on the opposite terminal side (C1-C6) were explored. Their structures were confirmed by several spectroscopic techniques (Fourier transform infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance spectroscopy). The mesomorphic properties of these compounds were studied by differential scanning calorimetry, polarized optical microscopy, and small- and wide-angle X-ray scattering. Except for the un-substituted terminals (C1 and C4), all other derivatives are liquid crystalline, exhibiting enantiotropic nematic liquid crystal phase. The alteration of the alkoxy chain length from methoxy to butoxy at the phenyl ester terminal group (ring A) for each set of laterally-neat and laterally methyl-substituted mesogens decreases the nematic temperature range. A decrease in the mesophase temperature range is also observed when a lateral methyl substituent is incorporated into phenylazo ring of the mesogenic core (ring C). Optical study demonstrated that their absorption spectra are identical in shape due to the structural similarities of the mesogenic core. The corresponding fluorescence spectra exhibited blue-emission with the laterally methyl substituted compounds having a relatively higher fluorescence intensity compared to that of its laterally un-substituted analogues. Furthermore, the laterally methyl-substituted derivatives were subjected to the planar alignment and their dielectric and electro-optic properties were investigated. The nematic phase of the aligned samples shows antiferroelectric switching behavior with spontaneous polarization, P-s similar to 5 mu C/cm(2). (C) 2021 Elsevier B.V. All rights reserved.

A highly efficient bifunctional catalyst of an s-triazine-based carbon-nitride-supported cobalt oxide is developed for the aerobic oxidation-Knoevenagel condensation tandem reaction of benzyl alcohol and malononitrile, whereby 96.4% benzyl alcohol conversion with nearly 100% selectivity towards benzylmalononitrile can be obtained in 6 h at 80 degrees C. The excellent catalytic performance derives from the high basicity of carbon nitride and strong redox ability of Co species induced by carbon nitride. The catalyst is also quite stable and can be reused without any regeneration treatment, whose product yield is only an 11.5% reduction after four runs.

Liquid liquid equilibrium (LLE) data for ternary systems of methyl isopropyl ketone (MIPK) + 2,3-/3,4-/3,5-dimethylphenol + water was determined from 298.15 K to 338.15 K under 101.3 kPa in this work. Distribution coefficient and selectivity were calculated to investigate solvent extraction efficiency of dimethylphenol from water and their high values indicated that MIPK could extract dimethylphenols well. The NRTL and UNIQUAC models were applied to correlate experimental LLE data and related root-mean square deviations (RMSDs) were less than 0.5%. Additionally, the experimental data was predicted by COSMO-SAC model, and the corresponding RMSD values demonstrated that COSMO-SAC model can be applied as a predictive tool to calculate LLE data of the investigated ternary systems.

As a promising biodegradable and biorenewable alternative to ubiquitous petrochemical plastics, poly(L-lactide) (PLLA) can be widely employed in biomedical and pharmaceutical fields. In this work, triblock copolymers, poly(L-lactide)-b-poly(2-methyl-1,3-propanediyl adipate)-b-poly(L-lactide) (PLLA-b-PMPA-b-PLLA)s, were synthesized by two-step polymerization from 2-methyl-1,3-propanediol (MP), adipic acid (AA) and L-lactide (LLA) as new biodegradable thermoplastic elastomers. The copolymers exhibited glass-transition temperature at below -40 degrees C and melting temperature at 140-160 degrees C. These copolymers showed much higher elongation at break and lower tensile modulus than those of PLLA. Enzymatic degradation tests of the obtained copolymers were performed using proteinase K and lipase PS as catalysts in hydrolysis reaction to demonstrate rapid degradation for these copolymers. Seawater biodegradability test was conducted for 28 days for each sample. The triblock copolymer and PMPA homopolymer were found to show about 50% biodegradation within 28 days representing very high biodegradable property in sea-water. (C) 2020 The Authors.
