The Asymmetric Synthesis of Amines via Nickel-Catalyzed Enantioconvergent Substitution Reactions

Chiral dialkyl carbinamines are important in fields such as organic chemistry, pharmaceutical chemistry, and bio-chemistry, serving for example as bioactive molecules, chiral ligands, and chiral catalysts. Unfortunately, most catalytic asymmetric methods for synthesizing dialkyl carbinamines do not provide general access to amines wherein the two alkyl groups are of similar size (e.g., CH2R versus CH2R1). Herein, we report two mild methods for the catalytic enantioconvergent synthesis of protected dialkyl carbinamines, both of which use a chiral nickel catalyst to couple an alkylzinc reagent (1.1-1.2 equiv) with a racemic partner, specifically, an a-phthalimido alkyl chloride or an N-hydroxyphthalimide (NHP) ester of a protected alpha-amino acid. The methods are versatile, providing dialkyl carbinamine derivatives that bear an array of functional groups. For couplings of NHP esters, we further describe a one-pot variant wherein the NHP ester is generated in situ, allowing the generation of enantioenriched protected dialkyl carbinamines in one step from commercially available amino acid derivatives; we demonstrate the utility of this method by applying it to the efficient catalytic enantioselective synthesis of a range of interesting target molecules.

On the Role of Metal-Containing Imidazolium-Based Ionic Liquid Catalysts in the Formation of Tailored Polystyrene

In this work, we synthesized ionic liquid (IL) catalysts based on 1-butyl-3-methylimidazolium chloride (BMI center dot Cl), incorporating various types of metal chlorides (as the anions) and in different molar ratios, for application in the styrene bulk cationic polymerization. The polymerizations proceeded with high reproducibility, and by employing some IL catalysts, high conversions were achieved in short times. The reactivity of these catalysts depended on the concentration of the metal chloride in the IL. The synthesized polymers presented different molar mass ranges (2.8 kg.mol(-1)<= (M) over bar (n) <= 556 kg.mol(-1)), molar-mass dispersities, and glass transition temperatures (T-g), depending on the catalytic system employed. Structural analysis by the H-1 NMR revealed that the end group of the polymer chain is a methyne group attached to a chlorine and some chains have the terminal indanyl group. The Schulz-Flory distributions indicated the existence of three to four catalytic species in the most active catalysts for the styrene polymerization. The polymerization was investigated by ESI(+)-MS(/MS), which showed the IL effect in the formation and stabilization of cationic intermediates.

Formation and degradation mechanisms of CX3R-type oxidation by-products during cobalt catalyzed peroxymonosulfate oxidation: The roles of Co3+ and SO4 center dot-

Sulfate radical (SO4 center dot-)-based advanced oxidation processes (AOPs) attract increasing attention in the control of micropollutants. However, SO4 center dot- can react with other chemicals present in water and result in undesired oxidation by-products (OBPs) generation. The formation and degradation mechanisms of CX3R-type OBPs during cobalt catalyzed peroxymonosulfate (Co2+/PMS) oxidation were investigated. In the formation of CX3R-type OBPs, both Co3+ and SO4 center dot- could convert chloride to free chlorine that then reacted with natural organic matter, leading to the formation of CX3R-type OBPs. The concentrations of trichloromethane, chloral hydrate, dichloroacetonitrile, dichloroacetamide and trichloroacetamide after 15 min reaction were 9.8, 3.9, 1.2, 5.9 and 22.3 nM, respectively. Compared to SO4 center dot-, Co3+ played a more significant role in the CX3R-type OBP formation and calculated toxicity values of CX3R-type OBPs. CX3R-type OBPs could not only be formed but also be degraded at the same time during Co2+/PMS oxidation. As for the degradation of CX3R-type OBPs, both Co3+ and SO4 center dot- could transform CX3R-type OBPs to chloride. Compared to Co3+, SO4 center dot- played a more important role in the degradation of CX3R-type OBPs and the conversion from chloride to final by-product chlorate. The adverse effects that results from Co3+ need more attention in SO4 center dot–based AOPs application.

Caffeine versus antioxidant combination (Antox) and their role in modifying cadmium-induced testicular injury in adult male albino rats

The aim of the current work was to compare the roles of caffeine and antioxidants in prevention of cadmium-induced testicular damage when given, in addition to cadmium, in adult male albino rats. Histopathological and ultra-structural examination as well as biochemical and molecular assessments were done. Cadmium chloride (4 mg/kg body weight) was administered via oral gavage from day 21 to 28 of the experiment. Caffeine (25 mg/kg) via intra-peritoneal injection and antioxidant preparation (Antox) 10 mg/kg via oral gavage were given as a pre-treatment for 21 days and concomitantly with Cd from day 21 to 28. Real-time PCR was done for determination of 3, 17 beta hydroxy steroid dehydrogenase steroidogenic acute regulatory protein, caspase-9 and mitofusin 1,2 gene expression. Testosterone level, glutathione S-transferase enzyme activity, reactive oxygen species, malondialdehyde and superoxide dismutase were measured spectrophotometrically by ELISA. Histological and ultra-structural evaluation revealed disturbance of normal architecture, vacuolisation and necrosis. Vascular dilatation and congestion and collagen fibre deposition were present. A statistically significant difference was seen in all parameters when caffeine and antioxidants were given against cadmium-induced testicular injury. Overall, we conclude that both caffeine and antioxidants have the ability to reverse cadmium-induced testicular injury when given as pre-treatment prior to cadmium exposure.

Microwave-assisted preparation of flower-like C-60/BiOBr with significantly enhanced visible-light photocatalytic performance

The surface properties of photocatalysts significantly affect the photocatalytic activity. For this reason, it is desirable to boost the photocatalytic activity of BiOBr photocatalysts via surface modification. In this demonstration, C-60 was used to decorate BiOBr by a microwave hydrothermal method. The flower-like C-60/BiOBr photocatalysts, assembled by nanosheets, were carefully examined with structural, optical, and compositional analyses. The results confirm that C-60 and BiOBr have been combined together. Because of the existence of synergistic interaction, C-60/BiOBr has a higher specific surface area, higher partition and migration of photo induced carriers, higher surface hydroxyl and O-center dot(2)- levels, higher oxygen vacancies (OVs) concentration on the catalytic surface. The formation of O-center dot(2)- was significantly enhanced, confirmed by nitrotetrazolium blue chloride (NBT) measurements. O-center dot(2)- can be effectively formed by two channels. Based on the photodestruction result of Rhodamine B (RhB), the photocatalytic activity of C-60/BiOBr composites was significantly boosted. In light of all the observations and the high electron affinity of C-60, separation of photoinduced carriers and a formation mechanism of active free radicals is proposed.

Fabrication of Microporous Polymeric Film via Colloid-Based Layer-By-layer Technology for CO2 Capturing

Large-scale and simple strategies to flexibly preparing materials with industrial application potential attract people’s attention. Layer-by-layer (LBL) self-assembly technology is a typical preparation method for current nanomaterials to address the large-scale concern and achieve the possibility of a simple, streamlined and controllable process. Here, a novel and simple strategy is developed to fabricate microporous polymeric film (MPF) based on poly(styrene-hydroxyethyl methylacrylate) (P(St-HEMA)) microspheres, in combination with LBL self-assembly technology and hypercrosslinked microporous post-treatment. To improve the mechanical properties of the film, the buffer layer of polyethyleneimine (PEI) and poly(sodium-p-styrenesulfonate) (PSS) are used to avoid swelling of nanoparticles and the methacryloxyethyltrimethyl ammonium chloride (DMC) is chosen to increase the force between the nanoparticles via UV-crosslinking. The MPF has well CO2 capture capabilities up to 46.21 wt% (10.52 mmol g(-1)), large-scale feature and certain improved mechanical properties. It is hoped that the research could display a successful strategy to prepare the large-scale film for the application of industrialization.

Approach to generating the right active phase in the Direct synthesis of trimethoxysilanes using the CuCl-Cu2O catalyst

The direct synthesis of trimethoxysilane (M3) by the reaction of Si with methanol over the Cud catalyst often generates a large amount of erosive HCl gas, causing severe environmental pollution. Thus, it calls for the development of greener and more efficient composite catalysts. In this work, to reduce the amount of CuCl, we employed three pretreatment methods to activate the contact mass of Si powder and the composite catalyst of CuCl and Cu2O. It was found that the contact mass activated by argon (Ar), hydrogen argon (H-2/Ar) and methyl chloride (CH3Cl), respectively, exhibited different catalytic performances: the highest Si conversion (34.1%) and M3 yield (24.0%) were obtained on the sample activated by CH3Cl. Notably, the M3 yield was increased 8-fold than that of the un-activated sample. The X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) studies revealed that different activation methods led to the generation of different kinds of CuxSi phases, such as Cu3Si and Cu4Si, both of which gradually transformed into Cu15Si4 during the reaction process. Pretreatment of the contact mass with CH3Cl promoted the formation of CuxSi, which contributed to the generation of more Cu15Si4 active phase, and finally to the superior catalytic performance.

Unexpected Boosted Solar Water Oxidation by Nonconjugated Polymer-Mediated Tandem Charge Transfer

Conjugated polymers are deemed as conductive carrier mediators for engendering the pi electrons along the molecular framework, while the role of nonconjugated insulated polymers has been generally overlooked without the capability to participate in the solar-powered oxidation-reduction kinetics and charge-transfer process. Alternatively, considering the ultrashort charge lifetime and significant deficiency of metal nanocluster (NC)-based photosystems, the fine tuning of charge migration over atomically precise ultrasmall metal NCs as novel light-harvesting antennas has so far not yet been unleashed. Here, we unlock the charge-transfer capability of a nonconjugated polymer to modulate the charge flow over metal NCs (Au-x and Au-25) by such a solid-state nonconductive polymer via a conceptually new chemistry strategy by which l-glutathione (GSH)-capped gold (Au-x@GSH) NCs and poly(diallyl-dimethylammonium chloride) (PDDA) were alternately self-assembled on the metal oxide (MO: WO3, Fe2O3, and TiO2) substrates. The ultrathin nonconjugated PDDA interim layer periodically intercalated in-between Au-x (Au-25) NC layers concurrently serves as an unexpected charge-transfer mediator to foster the unidirectional electron flow from Au-x(Au-25) NCs to MOs by forming a tandem charge-transfer chain, hence endowing the multilayered MO/(PDDA-Au-x)(n) heterostructures with significantly boosted photoelectrochemical water oxidation performance under light irradiation. The unanticipated role of PDDA as a cascade charge mediator is demonstrated to be universal. Our work would unlock the potential charge-transport capability of nonconjugated polymers as a novel charge mediator for solar-to-chemical conversion.

A Replacement Reaction Enabled Interdigitated Metal/Solid Electrolyte Architecture for Battery Cycling at 20 mA cm(-2) and 20 mAh cm(-2)

Metal anodes represent as a prime choice for the coming generation rechargeable batteries with high energy density. However, daunting challenges including electrode volume variation and inevitable side reactions preclude them from becoming a viable technology. Here, a facile replacement reaction was employed to fabricate a three-dimensional (3D) interdigitated metal/solid electrolyte composite electrode, which not only provides a stable host structure for buffering the volume change within the composite but also prevents side reactions by avoiding the direct contact between active metal and liquid electrolyte. As a proof-of-concept demonstration, a 3D interdigitated zinc (Zn) metal/solid electrolyte architecture was fabricated via a galvanic replacement reaction between Zn metal foil and indium (In) chloride solution followed by electrochemical activation, featuring the interdigitation between metallic Zn and amorphous indium hydroxide sulfate (IHS) with high Zn2+ conductivity (56.9 +/- 1.8 mS cm(-1)), large Zn2+ transference number (0.55), and high electronic resistivity [(2.08 +/- 0.01) x 10(3) Omega cm]. The as-designed Zn/IHS electrode sustained stable electrochemical Zn plating/stripping over 700 cycles with a record-low overpotential of 8 mV at 1 mA cm(-2) and 0.5 mAh cm(-2). More impressively, it displayed cycle-stable performance with low overpotential of 10 mV under ultrahigh current density and areal capacity (20 mA cm(-2), 20 mAh cm(-2)), which outperformed all the reported Zn metal electrodes in mild aqueous electrolyte. The fabrication of interdigitated metal/solid electrolyte was generalized to other metal pairs, including Zn/Sn and Zn/Co, which provide inspiration for next-generation Zn metal batteries with high energy density and reversibility.

Combination of temperature-assisted ternary phase homogenous liquid-liquid extraction with deep eutectic solvent-based dispersive liquid-liquid microextraction for the extraction of phytosterols from cow milk and cream samples

A three-phase homogenous liquid-liquid extraction method followed by deep eutectic solvent-based dispersive liquid-liquid microextraction has been used for the extraction and preconcentration of some phytosterols from cow milk and cream samples. In this method, cow milk or melted cream was transferred into a glass test tube and a mixture of sodium hydroxide solution (as fatty acids saponification agent) and acetonitrile (as extraction/dispersive solvent) was added to the solution. The mixture was shaken manually and placed in a water bath. After dissolving sodium chloride and centrifugation, the obtained supernatant phase (acetonitrile) was removed and mixed with ethyl methyl ammonium chloride: phenyl acetic acid deep eutectic solvent at microliter level. Under optimum conditions, low limits of detection (1.6-4.1 mu g/L) and quantification (5.3-13.1 mu g/L), high enrichment factors (138-207), and extraction recoveries (55-83%), and good precision (relative standard deviations <= 6.8%) can be obtained. The method was done on different milk and cream samples and the results showed that total phytosterols level in all samples were in the permitted level established by the National Standard Organization Guidelines, except for three cream samples.
