Metal-Lewis acid cooperation provides new opportunities in catalysis. In this work, we report a new type of palladium-borane cooperation involving anionic Pd-0 species. The air-stable DPB palladium complex 1 (DPB=diphosphine-borane) was prepared and reacted with KH to give the Pd-0 borohydride 2, the first monomeric anionic Pd-0 species to be structurally characterized. The boron moiety acts as an acceptor towards Pd in 1 via Pd -> B interaction, but as a donor in 2 thanks to B-H-Pd bridging. This enables the activation of C-Cl bonds and the system is amenable to catalysis, as demonstrated by the hydro-/deutero-dehalogenation of a variety of (hetero)aryl chlorides (20 examples, average yield 85 %).

Bio-based aromatic polyketones (PKs) and polyetherketones (PEKs) were synthesized by the electrophilic substitution reaction of alkoxylated divanillic acid (R-DVA) and 2,2′-dimethoxybiphenyl or diphenylether. Alkoxy side-chains were introduced at the hydroxyl groups of DVA prior to polymerization. Polymerizations were carried out in a phosphorus pentoxide (P2O5)/methanesulfonic acid (MsOH) system. DVA-based PKs and PEKs were soluble in common organic solvents including chloroform and dimethylsulfoxide, and their chemical structures were determined by H-1 and C-13 NMR. The weight-average molecular weights (M-w) of the PKs were 2.6-15.0 x 10(3) g/mol, and those of all PEKs were approximately 1.0 x 10(3). The 10% degradation temperatures of the PKs and PEKs were 340-400 degrees C. Dynamic mechanical analysis showed that the PKs and PEKs were amorphous. The PKs with methyl to butyl side-chains exhibited high glass transition temperatures (T-g) in the range 250-297 degrees C, while T-g of PK (octyl side-chain) was 157 degrees C and those of the PEKs were 73-127 degrees C.

Electrocatalytic hydrogenation (ECH) provides a green route to upgrade oxygenated bio-oil under mild conditions, but is still challenged with the issues of low working current density (<60 mA cm(-2)) and low faradaic efficiency (usually 20-60%) that seriously hinder its practical applications. Herein, we present a dual-catalyst electrochemical route that achieves extremely high faradaic efficiency (>99% for many chemicals) and high working current density (up to 800 mA cm(-2)) in the hydrogenation of model bio-oil compounds. More importantly, efficient deoxygenation to alkanes, often thought to be very difficult in conventional ECH, was achieved in the aqueous electrolysis. The dual-catalyst system consists of a suspended noble-metal catalyst and soluble polyoxometalate (POM). The theoretical calculations indicate that the POM functions as a superacid, changing the common hydrogenation route to a carbocation mechanism and resulting in effective electrolytic deoxygenation of oxygenates. Because no current flows through the catalyst, even a non-conductive catalyst can be used, which provides a great opportunity for extension to general applications.

Polybrominated diphenyl ethers (PBDEs) are ubiquitous compounds in the environment. Restrictions on the use of PBDEs introduced at the beginning of the 21st century have not eliminated these highly persistent and bioaccumulative compounds from the environment. Despite many existing regulations to control and phase out, extensive research on PBDEs is still necessary to fully evaluate the hazard their create to the environment. In most samples PBDEs occur at very low concentrations, which make analysis of these compounds difficult. The choice of an effective technique for the extraction of analytes that allows for their separation from interfering substances and the matrix is an important part of the analytical procedure for PBDEs determination. The paper presents a review of the literature on challenges related to the analysis of PBDEs in samples of different matrix compositions, the latest solutions used for sample preparation and future trends in sample preparation for PBDE analysis.

While infants are developing, they are easily affected by toxic chemicals existing in their environments, such as semi-volatile organic compounds (SVOCs): phthalates, polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), and organophosphate esters (OPEs). However, the specific living environment of infants, including increased plastic products and foam floor mats, may increase the presence of these chemicals, In this study, 68 air, dust, and window film samples were collected from homes, with 3- to 6-month-old infant occupants, to analyze phthalates, PAHs, PBDEs, and OPEs. High detection rates and concentrations suggest that these SVOCs are widespread in infant environments and are associated with cooking methods, smoking habits, the period of time after decoration, and room floors. The partitioning behavior of SVOCs indicates that the logarithms of the dust/gas-phase air partition coefficient (logK(D)) and the window film/gas-phase air partition coefficient (logK(F)) in homes are not at an equilibrium state when the logarithm of the octanol/air partition coefficient (logK(OA)) is less than 8 or greater than 11, Considering the 3 exposure routes, ingestion and dermal absorption have become the main routes of infant exposure to phthalates and OPEs, and ingestion and inhalation have become the dominant routes of exposure to PAHs and PBDEs. The total carcinogenic risk of SVOCs, which have carcinogenic toxicities, via ingestion and dermal absorption for infants in homes exceeds the acceptable value, suggesting that the current levels of these SVOCs in homes might pose a risk to infant health.

Studies of environmentally benign catalytic methods are of great value in modern chemical synthesis, especially the chemo-selective construction of chemical bonds under green conditions. This work elucidates such preferential synthesis of C-N bond over C-O bond via selective N-arylation of 3-aminophenols using 1,3-bis-[2-hydroxyphenyl] imidazolium chloride (IHPHCl) and copper iodide as catalyst (1 mol %) in aqueous medium. Presence of chelating group (-OH) on IHPHCl enhances N-selectivity. Overall this is a simple and green method for selective N-arylation of 3-aminophenols with good substrate scope and yields (60-88 %). GC-MS, HRMS and other spectroscopic techniques were utilised in detailing the kinetics and mechanistic aspects.

Despite the introduction of restrictive regulations in the USA and the European Union, polybrominated diphenyl ethers (PBDEs) are still found in various types of environmental and biological samples at significant concentration levels. The presence of these persistent organic pollutants in the environment raises important issues because of their negative impact on immunological and neurological systems, and on the hormonal balances in living organisms. From the analytical point of view, the final determination of PBDEs would entail substantial challenges, because it would necessitate conducting the pre-concentration of analytes, or sample clean up. The aim of the present study is to demonstrate the analytical application potential of developed dummy molecularly imprinted polymers as solid-phase extraction sorbents for the selective recognition of low-mass PBDEs. The 4,4′-dihydroxydiphenyl ether was employed as a dummy template of low-mass PBDEs. The developed types of the sorption materials were used in the sample preparation stage of the analytical procedure to determine the PBDE-47 and PBDE-99 levels in selected representatives of environmental samples reference materials of soil and bottom sediments. The recovery values of PBDE-47 and PBDE-99 from the studied solid samples ranged from 60% to 87%, depending on the applied DMIPs type.

Polybrominated diphenyl ethers (PBDEs) are widespread persistent organic pollutants (POPs) because of their extensive use in diverse electronic products, which have posed great threats to human health and ecosystem. In this study, a total of 54 soil samples were collected from an e-waste recycling area in Tianjin, northern China for analyzing the occurrence and distribution of 14 PBDE congeners. The concentrations of BDE 209, Sigma 13PBDEs and E14PBDEs in the soils from Ziya e-waste recycling area were 2.9-2666 ng/g dw (dry weight) (average 90 ng/g dw), 3.0-41 ng/g dw (average 13 ng/g dw) and 5.9-2699 ng/g dw (average 103 ng/g dw), respectively. The Sigma 14PBDEs concentration showed a dramatic decrease from the central area to the surrounding area. Generally, PBDEs in the northern part showed higher levels than the southern part of the e-waste recycling area due to the wind direction in Tianjin. Deep soil was less polluted by PBDEs, which largely comes from the deposition, migration and infiltration of PBDEs in the surface soils. Overall, PBDEs level in the studied area was much lower than some typical e-waste recycling areas in south China, such as Guiyu and Qingyuan, but significantly higher than the non-e-waste recycling areas. BDE 209, BDE 138 and BDE 28 were the three dominant PBDE congeners in the soil. Principal component analysis (PCA) indicated that the commercial penta-BDEs and deca-BDE could be considered as the main sources of PBDEs pollution in this region. Redundancy analysis (RDA) suggested that the local PBDEs sources rather than soil properties influenced the PBDEs distribution in Ziya e-waste recycling area. This study systematically revealed the occurrence and distribution of PBDEs in soils from the biggest established circular economy park in northern China.

A tricomponent catalyst comprising titanium tetrachloride, triisobutyl aluminum and diphenyl ether is developed for the highly cis-1,4-selective polymerization of isoprene. The influence of the content of diphenyl ether and its complexation order on polymerization, microstructure and performance of polyisoprene are studied. The polyisoprene synthesized presents high monomer conversion (91-99%). With the increasing of diphenyl ether content, intrinsic viscosity and viscosity-average molecular weight of polyisoprene increase. The molar percentage of cis-1,4-unit is almost unaffected by diphenyl ether and different complexation sequence. The polyisoprene reveals comparable T-g (-61.31 degrees C) and mechanical strengths (11.14MPa, 667%) to commercially available LHIR-80 synthesized with neodymium. However, the viscosity and viscosity-average molecular weight of the former are lower than that of the latter, which avails the processability and maintains excellent mechanical properties.

A hydrogen bond (HB) is an essential interaction in countless phenomena, regulating the chemistry of life. HBs are characterized by two features, strength and directionality, with a high degree of heterogeneity across different chemical groups. These characteristics are dependent on the electronic configuration of the atoms involved in the interaction, which, in turn, is influenced strongly by the local molecular environment. Studies based on the analysis of HB in the solid phase, such as X-ray crystallography, suffer from significant biases due to packing forces. These will tend to better describe strong HBs at the expenses of weak ones, which will be either distorted or under-represented. Using quantum mechanics (QM), we calculated interaction energies for about a hundred acceptors and donors in a rigorously defined set of geometries. We performed 180,000 independent QM calculations, covering all relevant angular components, mapping strength and directionality in a context free from external biases, with both single-site and cooperative HBs. By quantifying directionality, we show that there is no correlation with strength; therefore, these two components need to be addressed separately. Results demonstrate that there are very strong HB acceptors (e.g., dimethyl sulfoxide) with nearly isotropic interactions and weak ones (e.g., thioacetone) with a sharp directional profile. Similarly, groups can have comparable directional propensity but be very distant in the strength spectrum (e.g., thioacetone and pyridine). Results provide a new perspective on the way HB directionality is described, with implications for biophysics and molecular recognition that ultimately can influence chemical biology, protein engineering, and drug design.
