Aramid nanofiber reinforced nitrile rubber assisted by cellulose nanocrystals

A fiber-reinforced rubber composite was prepared by mixing aramid nanofibers (ANF) suspension and nitrile rubber (NBR) latex. The effects of ANF content and corresponding surface modification on the microstructure, vulcanization performance, processing and mechanical properties of composite materials, were systematically investigated. We found that, compared with commonly used short-cut aramid fibers, ANF fillers tend to form a stronger filling network within NBR matrix, resulting in a pronounced Payne effect. By improving the interfacial adhesion via dopamine (DA) coating onto ANF surface, the tensile strength can be further enhanced as expected. Besides, to eliminate the detriment of mechanical performance due to residual sodium polyacrylate in the course of flocculation, cellulose nanocrystal (CNC) was adopted to serve as a thickener during solution mixing. The incorporation of CNC can significantly improve the mechanical properties, which identifies a synergistic reinforcement effect arising from the cooperation of two types of fillers.

Pd-Catalyzed Approach for Assembling 9-Arylacridines via a Cascade Tandem Reaction of 2-(Arylamino)benzonitrile with Arylboronic Acids in Water

A novel palladium-catalyzed protocol for the synthesis of 9-arylacridines via tandem reaction of 2-(arylamino)benzonitrile with arylboronic acids in water has been developed with good functional group tolerance. The present synthetic route could be readily scaled up to gram quantity without difficulty. This methodology was further extended to the synthesis of a 4′-OH derivative, which showed estrogenic biological activity. Preliminary mechanistic experiments showed that this transformation involves a nucleophilic addition of aryl palladium species to the nitrite to generate an aryl ketone intermediate followed by an intramolecular Friedel-Crafts acylation and dehydration to acridines.

Z-Selective alpha-Arylation of alpha,beta-Unsaturated Nitriles via [3,3]-Sigmatropic Rearrangement

The Morita-Baylis-Hillman (MBH) reaction and [3, 3]-sigmatropic rearrangement are two paradigms in organic synthesis. We have merged the two types of reactions to achieve [3,3]-rearrangement of aryl sulfoxides with alpha,beta-unsaturated nitriles. The reaction was achieved by sequentially treating both coupling partners with electrophilic activator (Tf2O) and base, offering an effective approach to prepare synthetically versatile alpha-aryl alpha,beta-unsaturated nitriles with Z-selectivity through direct alpha-C-H arylation of unmodified alpha,beta-unsaturated nitriles. The control experiments and DFT calculations support a four-stage reaction sequence, including the assembly of Tf2O activated aryl sulfoxide with alpha,beta-unsaturated nitrile, MBH-like Lewis base addition, [3,3]-rearrangement, and E1cB-elimination. Among these stages, the Lewis base addition is diastereoselective and E1cB-elimination is cis-selective, which could account for the remarkable Z-selectivity of the reaction.

alpha-Iminonitriles: Composite Functional Groups for Functionalization of Pyrene

Functionalization of polycyclic aromatic hydrocarbons (PAHs) with functional groups is essential for tuning the optoelectronic properties, solid stacking and solubility. alpha-Iminonitriles are composite functional groups (CFGs) containing imine (C=N-R) and nitrile (CN) moieties with strong electron-withdrawing character and good stability, which could be readily introduced through several effective synthetic methods. alpha-Iminonitriles have been widely used as intermediates for organic transformations but hold untapped potential for modification of organic functional materials. We herein disclose that alpha-iminonitriles are eminent groups for modifying the properties of pyrene. The introduction of alpha-iminonitriles to pyrene causes many changes: significantly lowering the LUMOs, red-shift in absorption and emission spectra, tuning the solid-stacking, triggering aggregation-induced emission and white-light emission. This work indicates that CFGs such as alpha-iminonitriles may provide extra toolkits for the functionalization of organic functional materials which would help to tap the potentials of novel or existed materials.

Magnetically enhanced polymer-supported ceria nanocatalysts for the hydration of nitriles

The heterogeneous catalysis of the hydration of nitriles to amides is a process of great industrial relevance in which cerium(IV) oxide (also referred to as ceria) has shown an outstanding catalytic performance. The use of non-supported ceria nanoparticles is related to difficulties in the purification of the product and the recovery and recyclability of the catalyst. Therefore, in this work, ceria nanoparticles are supported on a polymer matrix either by synthesizing polymer particles by so-called Pickering miniemulsions while using ceria nanoparticles as emulsion stabilizers or, as a comparison, byin-situcrystallization on preformed polymer particles. The former strategy presents significant advantages over the latter in terms of time and consumption of resources, and it facilitates an easier scale-up of the process. In both strategies, the incorporation of a magnetoresponsive core within the polymer matrix allows the recovery and the recycling of the catalyst by simple application of a magnetic field and offers an enhancement of the catalytic efficiency.

Effect of Particle Wettability and Particle Concentration on the Enzymatic Dehydration of n-Octanaloxime in Pickering Emulsions

Pickering emulsion systems have emerged as platforms for the synthesis of organic molecules in biphasic biocatalysis. Herein, the catalytic performance was evaluated for biotransformation using whole cells exemplified for the dehydration of n-octanaloxime to n-octanenitrile catalysed by an aldoxime dehydratase (OxdB) overexpressed in E. coli. This study was carried out in Pickering emulsions stabilised solely with silica particles of different hydrophobicity. We correlate, for the first time, the properties of the emulsions with the conversion of the reaction, thus gaining an insight into the impact of the particle wettability and particle concentration. When comparing two emulsions of different type with similar stability and droplet diameter, the oil-in-water (o/w) system displayed a higher conversion than the water-in-oil (w/o) system, despite the conversion in both cases being higher than that in a classic two-phase system. Furthermore, an increase in particle concentration prior to emulsification resulted in an increase of the interfacial area and hence a higher conversion.

Nickel-Catalyzed [4+2] Annulation of Nitriles and Benzylamines by C-H/N-H Activation

Nickel-catalyzed [4 + 2] annulation of benzylamines and nitriles via C-H/N-H bond activation, providing straightforward atom-economic access to a wide variety of multisubstituted quinazolines, is reported. Mechanistic investigation revealed that the in situ formed amidines from the coupling of benzylamines and nitriles direct the nickel catalyst to activate the ortho-C-H bond of the phenyl ring of the benzylamine.

Degradation of neonicotinoid insecticide acetamiprid by two different nitrile hydratases of Pseudaminobacter salicylatoxidans CGMCC 1.17248

Acetamiprid is a neonicotinoid insecticide used worldwide that has caused environmental pollution and adverse effects on ecosystems. Here, a novel bacterium, Pseudaminobacter salicylatoxidans CGMCC 1.17248, was isolated to rapidly degrade acetamiprid to IM-1-2 via hydration. Gene cloning and overexpression demonstrated that two nitrile hydratases, AnhA and AnhB, converted acetamiprid to IM-1-2. Escherichia coli overexpressing AnhA and AnhB degraded 98.1% and 94.0% of acetamiprid (1.0 mmol L-1) in 5 min and 8 h, respectively. The pure AnhA and AnhB had a V-max value of 14.12 and 1.20 mu mot mg(-1 )min(-1), respectively, and a K-m value of 1.02 mmol L-1 and 2.95 mmol L-1, respectively. Compared with AnhA, AnhB had broad pH stability, as well as metal ions and organic solvents tolerance. Expression of AnhA and AnhB was induced by decreasing the nutrient concentration of culture broth and addition of urea and therefore significantly enhanced acetamiprid degradation of CGMCC 1.17248. qPCR indicated that the expression of AnhA and AnhB under the cultured conditions of 1/15 lysogeny broth or 0.5% urea addition was improved by from 2.2 to 5.3 times. The results presented herein will facilitate development of bioremediation agents for acetamiprid pollution and understanding of the functional role of bacterial nitrile hydratase.

An updated asymmetric total synthesis of (+)-tronocarpine

An updated route for the asymmetric total synthesis of (+)-tronocarpine is presented. By a careful modification of the synthetic strategies and methods for the construction of azepanone ring and for the incorporation of acetyl side group at C-20 based on our experiences for the synthesis of chippiine-dippinine type indole alkaloids, the synthesis of (+)-tronocarpine could be shortened from 15 longest linear sequences (LLSs) to 11 LLSs starting from an easily prepared intermediate. The new synthetic route presented herein would provide a more efficient synthesis of (+)-tronocarpine as well as its analogues for biological evaluation which remained unexplored due to the paucity of natural sources.

Synthesis of fully asymmetric diketopyrrolopyrrole derivatives

Diaryl-diketopyrrolopyrroles (DPP) are a widely studied class of chromophore that possesses unique properties which have been of great interest for use in conjugated polymers and as small molecules in optoelectronic devices. While previously only partially asymmetric DPP derivatives have been reported, here a novel methodology towards fully asymmetric DPP derivatives is demonstrated via the synthesis and condensation of novel alkylated thienyl pyrrolinone esters with aromatic nitriles followed by N-alkylation. Two fully asymmetric DPP structural isomers T-DPP-P and P-DPP-T were synthesised demonstrating the full customizability of the DPP core. A further two fully asymmetric DPP derivatives incorporating an ethylene glycol chain and a furan moiety were also synthesised, demonstrating the scope of this powerful methodology and it’s potential to largely broaden the library of available DPP derivatives.
