Rotaxane-Based Difunctional Nitrile N-Oxide Crosslinker: Synthesis and Direct Introduction of Movable Crosslinking Points into Ethylene-Propylene-Butadiene Monomer (EPDM) Rubber

Incorporation of rotaxane scaffolds into the crosslinking points of polymer networks significantly affects their rheological and mechanical properties. The present study involves the synthesis of a new rotaxane-type crosslinker containing nitrile N-oxide functional groups on both the axle and wheel components. The prepared crosslinker is highly reactive; however, it can be isolated and applied in the crosslinking reaction of a commercially important polymer, namely ethylene-propylene-butadiene monomer rubber (EPDM), in the absence of additives and catalysts. Tensile tests reveal that compared to a network containing conventional crosslinking points, both breaking strength and strain of the network structure prepared herein are improved due to the incorporation of movable crosslinking points. The synthesized network structure also exhibits five times higher fracture energy. The developed post-crosslinking methodology for the direct introduction of movable crosslinking points into pre-formed polymers will be valuable in the production of rotaxane materials for various applications.

Radical Annulation for the Synthesis of Cyclopenta[c]chromene Derivatives

A Cu-catalyzed oxidative radical [2+2+1] annulation reaction of phenol-linked 1,7-enynes with alpha-active methylene nitrile is described, affording cyclopenta[c]chromene derivatives bearing several functional groups in excellent yields. The wide substrate range, good group tolerance, and easy amplification experiments indicate the practicability of this synthesis strategy. This process provides an alternative convenient route for the synthesis of cyclopenta[c]chromene derivatives.

Design of heat-triggered shape memory polymers based on ethylene-acrylic acid copolymer/nitrile-butadiene rubber thermoplastic vulcanizates

Heat-triggered shape memory polymers (HSMPs) consisting of ethylene-acrylic acid copolymer (EAA) and nitrile-butadiene rubber (NBR) were fabricated by peroxide-induced dynamic vulcanization; meanwhile, in order to realize rapid and reconfigurable shape fixity and shape recovery, a facile and effective strategy was designed. Morphological structure and interface interaction are decisive factors for HSMPs, the FE-SEM images showed the average diameter of NBR particles in EAA/NBR TPVs was 5 to 8 mu m and the strong interface interaction between EAA matrix and NBR particles provided critical assistance in keeping the temporary shape of deformed rubber particles and storing stronger elastic driving force. The shape memory behavior of EAA/NBR TPVs was characterized and the result demonstrated that excellent shape-fixity (>91%), shape-recovery (>93%), and fast recovery speed (<30 s) could be obtained at suitable deformation temperature of 95 degrees C. The results of dynamic mechanical analysis and shape memory research showed that the high modulus value supported the improvement of shape-fixity ratio and the appropriate ratios of EAA/NBR TPVs were the key factors for excellent shape memory performance. The novel HSMPs expected to open up potential applications in the field of sensors and self-assembling smart devices.

Metal-catalyzed cyanation of aromatic hydrocarbon with less toxic nitriles as a cyano source

Less toxic and inexpensive organic nitriles as cyano sources for the cyanation of various substituted aromatic hydrocarbons such as aryl halides, aryl boronic acids, aryl carboxylic acids, indoles, diazoarenes, aryl alkynes, aryl sulfonamides and directing groups substituted arenes were reviewed. Lately, much process is made in realizing the possibility of less toxic cyanide sources such as as organic nitriles (MeCN, DMF, MeNO2, DMSO, TsCN, BrCN, ArOCN, AMBN, AlBN, ArCH2CN) for the cyanation and these CN sources when used as a slow dosage cyanide source could solve the problem of using metal cyanides (K-4[Fe(CN)(6)], Zn(CN)(2), KCN, CuCN, NaCN) that cause rapid deactivaction of catalyst. To provide solution for these problems, we discussed new Pd, Cu, Ru, Rh, and Ni catalyzed systems to achieve the cyanation with slow-release cyanide sources. Thus, the focus of the review is to highlight and make known the problems associated with metal catalysts and cyano sources. (C) 2020 Elsevier Ltd. All rights reserved.

Copper Catalyzed Oxidative Arylation of Tertiary Carbon Centers

We describe herein a Cu(OTf)(2) catalyzed oxidative arylation of a tertiary carbon-containing substrate including aryl malononitriles, 3-aryl benzofuran-2-ones, and 3-aryl oxindoles. In some cases, the nitrile groups of the aryl malononitriles undergo further reactions leading to lactones or imines. These reaction conditions are applicable for a range of arenes, including phenols, anilines, anisoles, and heteroarenes. Mechanistic studies support the formation of a cationic intermediate via a two-electron oxidation.

Enantioselective Cyanoborylation of Allenes by N-Heterocyclic Carbene-Copper Catalysts

The simultaneous incorporation of both a cyano group and a boryl unit into the C=C double bonds of allenes in a regio- and stereoselective fashion is of much interest and importance but remains a significant challenge. We report herein a copper-catalyzed chemo-, regio-, and enantioselective cyanoborylation of allenes, which afforded a family of valuable enantiopure beta-boryl allyl nitriles. The high enantioselectivity was achieved by installing of appropriate substituents at the C2 and C6 positions of the naphthyl groups in our newly synthesized N-heterocyclic carbene (NHC) ligands. The reaction mechanism has been clarified by some stoichiometric reactions and computational studies. This work provides an inspiring example of the development of selective catalytic reactions for the synthesis of functional molecules through fine-tuning the ligands in catalysis.

Rheological and Mechanical Properties of Silica/Nitrile Butadiene Rubber Vulcanizates with Eco-Friendly Ionic Liquid

In this paper we designed greener rubber nanocomposites exhibiting high crosslinking density, and excellent mechanical and thermal properties, with a potential application in technical fields including high-strength and heat-resistance products. Herein 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc) ionic liquid was combined with silane coupling agent to formulate the nanocomposites. The impact of [EMIM]OAc on silica dispersion in a nitrile rubber (NBR) matrix was investigated by a transmission electron microscope and scanning electron microscopy. The combined use of the ionic liquid and silane in an NBR/silica system facilitates the homogeneous dispersion of the silica volume fraction (phi) from 0.041 to 0.177 and enhances crosslinking density of the matrix up to three-fold in comparison with neat NBR, and also it is beneficial for solving the risks of alcohol emission and ignition during the rubber manufacturing. The introduction of ionic liquid greatly improves the mechanical strength (9.7 MPa) with respect to neat NBR vulcanizate, especially at high temperatures e.g., 100 degrees C. Furthermore, it impacts on rheological behaviors of the nanocomposites and tends to reduce energy dissipation for the vulcanizates under large amplitude dynamic shear deformation.

Palladium-catalyzed cascade reactions in aqueous media: synthesis and photophysical properties of pyrazino-fused quinazolinones

Heterocycle-fused quinazolinone derivatives have attracted great attention due to their diversified biological and optical activities. In this study, a novel one-pot palladium-catalyzed cascade C-C coupling/cyclization/aromatization of 2-(4-oxoquinazolin-3(4H)-yl)acetonitrile derivatives with arylboronic acids has been disclosed to synthesize 1,3-diaryl-6H-pyrazino[2,1-b]quinazolin-6-one in water. This protocol provides an efficient access to valuable pyrazino-fused quinazolinones in a green solvent (i.e., water) with yields ranging from moderate to excellent. Furthermore, the photophysical properties of these molecules were investigated. The resultant pyrazino-fused quinazolinones exhibit tunable fluorescence, and 3e displays the aggregation induced emission properties with a large Stokes shift. This study provides a useful approach to the development of pyrazino-fused quinazolinones, which have potential applications in chemistry, biology, and materials science.

Enhanced thermal conductivity of carboxyl nitrile butadiene rubber composites with low-cost poly(catechol/polyamine) modified Al2O3 via biomimetic method

With the miniaturization, integration, and functionalization of the electronic components, heat dissipation in the electronic devices has become a challenging issue. Owing to high polarity, carboxyl nitrile butadiene rubber (XNBR) is usually employed as a dielectric material in the electronic devices. However, low thermal conductivity of XNBR hardly satisfies the increasingly stricter demands for heat dissipation. Herein, we used low-cost poly (catechol/polyamine) (PCPA) to modify Al2O3 nanoparticles via biomimetic method for enhancing the interfacial interaction between the Al2O3 filler and XNBR. The ortho-polyphenols in catechol were oxidized into orthoquinone groups in the alkaline solution. Then, the ortho-quinone groups formed a cross-linked structure to obtain PCPA via the Michael addition or Schiff base reaction with amine. The process decreased the interfacial thermal resistance and phonon scattering, resulting in an enhanced thermal conductivity. When the Al2O3-PCPA nanoparticles content was 30 vol%, the thermal conductivity of XNBR based composites reached up to 0.51 W/ mK, which was 3.19 times that of pure XNBR (0.16 W/mK). The proposed method has potential applications in large scale production of thermally conductive composites in industries, such as electronic packaging materials and thermal management materials.
