Rhodium-Catalyzed Regioselective 3-Fluoroallylic Cyanation

A rhodium catalyzed allylic cyanation of 3-fluoroallylic trifluoroacetates with TMSCN and a bulky phosphite ligand gives 3-fluoroallylic nitriles with a good substrate scope and high Z/E-selectivity. For dialkylated substrates the fluorine substituent controls the regioselectivity in favor of the distal product. For the stereoselectivity of the allylic cyanation selected scalemic substrates showed inversion of the stereocenter and some or no stereoerosion.

Efficient alpha-Alkylation of Arylacetonitriles with Secondary Alcohols Catalyzed by a Phosphine-Free Air-Stable Iridium(III) Complex

A well-defined and readily available air-stable dimeric iridium(III) complex catalyzed alpha-alkylation of arylacetonitriles using secondary alcohols with the liberation of water as the only byproduct is reported. The alpha-alkylations were efficiently performed at 120 degrees C under solvent-free conditions with very low (0.1-0.01 mol %) catalyst loading. Various secondary alcohols including cyclic and acyclic alcohols and a wide variety of arylacetonitriles bearing different functional groups were converted into the corresponding alpha-alkylated products in good yields. Mechanistic study revealed that the reaction proceeds via alcohol activation by metal-ligand cooperation with the formation of reactive iridium-hydride species.

Ru-II and Ru-III Chloronitrile Complexes: Synthesis, Reaction Chemistry, Solid State Structure, and (Spectro)Electrochemical Behavior

The synthesis of [Ti6O4(OiPr)(8)(O2CPh)(8)] (3) and [RuCl(N equivalent to CR)(5)][RuCl4(N equivalent to CR)(2)] (4a, R = Me; 4b, R = Ph), [Ru(N equivalent to CPh)(6)][RuCl4(N equivalent to CPh)(2)] (5) and [H3O][RuCl4(N equivalent to CMe)(2)] (7a) is discussed. Crystallization of 5 from CH2Cl2 gave trans-[RuCl2(N equivalent to CPh)(4)] (6). The solid-state structures of 3, 4a,b, 5, 6 and 7a are reported. Complex 4b forms a 3D network, while 6 displays a 2D structure, due to pi-interactions between the benzonitrile ligands. The (spectro)electrochemical behavior of 4a,b and 6 was studied at 25 and -72 degrees C and the results thereof are compared with [NEt4][RuCl4(N equivalent to CMe)(2)] (7b) and [RuCl(N equivalent to CPh)(5)][PF6] (8). The electrochemical response of the cation and the anion in 4a,b are independent from each other. [RuCl(N equivalent to CR)(5)](+) possesses one reversible Ru-II/Ru-III process. However, [RuCl4(N equivalent to CMe)(2)](-) was shown to be prone to ligand exchange and disproportionation upon formation of either a Ru-IV and Ru-II species at 25 degrees C, while at -72 degrees C the rapid conversion of the electrochemically formed species is hindered. In situ IR and UV/Vis/NIR studies confirmed the respective disproportionation reaction products of the aforementioned oxidation and reduction, respectively.

Electrically conductive NBR/CB flexible composite film for ultrastretchable strain sensors: fabrication and modeling

In this study, a flexible strain sensor with ultrahigh stretchability, outstanding sensitivity, and excellent repeatability based on conductive carbon black (CB) and nitrile butadiene rubber (NBR) was presented. Two organic solvents with three different coating time during the dissolve-coating process were investigated. The morphology and the degradation temperature of all the NBR/CB composite films were studied, and the tensile strength, elongation at break, as well as the young’s modulus and the dissipated energy for all the specimen were revealed. The strain-sensing tests indicated that the NBR/CB film possess a good sensitivity (max. gauge factor = 24.9) and an ultrahigh sensing range (max. 681% strain). The mathematic model from Simmons for predicting the sensing behavior based on the tunneling theory was further simplified, and a novel equation was proposed for predicting the relative change of resistance as a function of time during the cyclic test, which showed great agreement with the cyclic strain-sensing data in experiments. Overall, this study introduces a simple low-cost fabrication method for preparing the polymeric flexible strain sensors with great strain-sensing performance. The development of the two mathematical modellings makes several noteworthy contributions to the existing knowledge of strain-sensing behavior.

Cross-Linking of Rubber Matrices with Dicumyl Peroxide and Zinc Dimethacrylate. Part I: Effect of Co-Agent Content

The work is focused on the investigation of the influence of the amount of co-agent on cross-linking and properties of rubber compounds. The in-situ radical polymerization of zinc dimethacrylate occurs during the curing process of rubber compounds with organic peroxide. Polymerized zinc dimethacrylate tends to form different types of chemical and physical linkages within the rubber matrices. As the amount of dimethacrylate ranged from 10 to 50 phr, the conversion of zinc dimethacrylate remained low. Residual zinc dimethacrylate formed micro-dispersion in the rubber matrix. The dispersion and distribution of zinc dimethacrylate in the rubber depends on the viscosity of matrix, shear stress and polarity of the matrix. Despite low conversion of zinc dimethacrylate, the application of co-agent resulted in the increase of cross-link density and improvement of physical-mechanical properties of vulcanizates.

Theoretical Study of the Mechanism of Palladium(0)-Catalyzed Intramolecular [2+2+2] Cycloaddition of Ester-Substituted Alkynes

The mechanisms of the palladium(0)-catalyzed cross [2+2+2] cycloaddition of a diyne diester with dimethyl acetylenedicarboxylate and of the [2+2+2] cyclization of a triyne diester were investigated using density functional theory calculations. After evaluating the kinetic and thermodynamic profiles of each reaction, the roles of the ester substituents on the alkyne substrates and of the triphenylphosphine ligand are discussed based on the obtained results. Moreover, the previously unreported cross [2+2+2] cycloaddition of the diyne diester with nitriles was also investigated, in order to evaluate its feasibility under the relevant experimental conditions.

Realizing a high-performance LiNi0.6Mn0.2Co0.2O2/silicon-graphite full lithium ion battery cellviaa designer electrolyte additive

An optimized dosage of (2-cyanoethyl)triethoxysilane (TEOSCN), is investigated as the electrode/electrolyte interface (EEI) modulating electrolyte additive to improve electrochemical performance of LiN0.6Mn0.2Co0.2O2(NMC622)/silicon(Si)-graphite(Gr) battery cells at a high temperature (45 degrees C). The addition of 1 wt% of TEOSCN to 1 M LiPF(6)in EC:DEC + 5 wt% FEC/2 wt% VC electrolyte is found to significantly improve the long-term cyclability, capacity retention and coulombic efficiency of NMC622/Si-Gr cells at 45 degrees C. Pouch cells cycled in a nitrile-functionalized silane bearing electrolyte show superior capacity retention (similar to 75.95%) compared to those with FEC/VC (similar to 8.05%) and without additives (EC:DEC, similar to 19.23%) electrolytes at the 364(th)cycle. Chemical mimicking and X-ray Photoelectron Spectroscopy (XPS) analysis proved that the enhanced electrochemical performance is attributed to the formation of -C equivalent to N reduction/oxidation induced robust EEI layers, both on the anode and cathode compartments, thus mitigating the escorted prevailing challenges. This work provides a highly promising electrolyte additive enabling the large-scale commercial deployment of Si-containing high-energy lithium-ion full cell batteries.

Dipeptidyl nitrile derivatives suppress the Trypanosoma cruzi in vitro infection

Chagas disease affects several countries around the world with health and sanitation problems. Cysteine proteases are essential for the virulence and replication of the Trypanosoma cruzi, being modulated by dipeptidyl nitriles and derivatives. Here, four dipeptidyl nitrile derivatives were assayed in three T. cruzi morphologies and two strains (Tulahuen and Y) using a set of assays: (i) analysis of the inhibitory activity against cysteine proteases; (ii) determination of the cytotoxic activity and selectivity index; (iii) verification of the inhibition of the trypomastigote invasion in the host cell. These compounds could inhibit the activity of cysteine proteases using the selective substrate Z-FR-MCA for the trypomastigote lysate and extracellular amastigotes. Interestingly, these compounds did not present relevant enzymatic inhibition for the epimastigote lysate. Most of the substances were also cytotoxic and selective against the trypomastigotes and intracellular amastigotes. The best compound of the series (Neq0662) could reduce the enzymatic activity of the cysteine proteases for the trypomastigotes and amastigotes. It was equipotent to the benznidazole drug in the cytotoxic studies using these two parasite forms. Neq0662 was also selective for the parasite, and it inhibited the invasion of the mammalian host cell in all conditions tested at 10 mu M. The stereochemistry of the trifluoromethyl group was an important factor for the bioactivity when the two diastereomers (Neq0662 and Neq0663) were compared. All-in-all, these results indicate that these compounds could move further in the drug development stage because of its promising bioactive profile.
