Simultaneous enhancement of dielectric and mechanical properties ofhigh-density polyethylene/nitrile rubber/multiwalled carbon nanotubecomposites prepared by dynamic vulcanization

Polymer dielectric composites, which possess high dielectric and loss suppression with excellent mechanical properties, are of crucial importance in practical applications. Herein, high-density polyethylene/nitrile rubber/multiwalled carbon nanotube (HDPE/NBR/MWCNT) composites were fabricated by the dynamic vulcanization (DV) technique. The effect of DV on the structure and properties of HDPE/NBR/MWCNTs was systematically investigated. The results illustrate that the DV technique combines the advantages of the crosslinked phase and melt processability of thermoplastics. With the increase of dicumyl peroxide content, the dielectric permittivity and the mechanical properties clearly increase, due to a better compatibility and dispersibility achieved by DV. More importantly, a continuous decrease of dielectric loss and conductivity are observed with the increase of dicumyl peroxide content. These can probably be assigned to the combination of better dispersion and slower chain mobility of the NBR phase induced by crosslinking. (c) 2020 Society of Industrial Chemistry

General Synthesis of Secondary Alkylamines by Reductive Alkylation of Nitriles by Aldehydes and Ketones

The development of C-N bond formation reactions is highly desirable due to their importance in biology and chemistry. Recent progress in 3d metal catalysis is indicative of unique selectivity patterns that may permit solving challenges of chemical synthesis. We report here on a catalytic C-N bond formation reaction-the reductive alkylation of nitriles. Aldehydes or ketones and nitriles, all abundantly available and low-cost starting materials, undergo a reductive coupling to form secondary alkylamines and inexpensive hydrogen is used as the reducing agent. The reaction has a very broad scope and many functional groups, including hydrogenation-sensitive examples, are tolerated. We developed a novel cobalt catalyst, which is nanostructured, reusable, and easy to handle. The key seems the earth-abundant metal in combination with a porous support material, N-doped SiC, synthesized from acrylonitrile and a commercially available polycarbosilane.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 29968-78-3 is helpful to your research. Name: 4-Nitrophenylethylamine hydrochloride.

Selective 1,4-Addition of Organolithiums to Maleate Monoesters with Application for a Short Efficient Route to Azaindanones

The ability of maleate half-ester salts to serve as electrophilic partners in 1,4-conjugate addition reactions with control of regioselectivity has previously been explored in only a limited context with soft nucleophiles. We have demonstrated that benzylic anions of picolines, as well as enolates of ketones, esters, and nitriles, react with lithium 4-( tert -butoxy)-4-oxobutenoate in a completely regioselective manner. This new method was applied to an expedient two-step process for preparing a key azaindanone intermediate for the clinical-candidate drug MK-8666.

ASYMMETRIC CATALYSIS .4. HYDROSILYLATION OF ACETOPHENONE WITH PYRROLINE-2,5-DIONE MODIFIED [RH(COD)CL](2) CATALYSTS

The reaction of dichloromaleimides with optically active amines affords chiral pyrrolin-2,5-diones. The diamines are C-13-NMR-spectroscopically characterized. In addition, the molecular structure of 1-(R)-menthyl-3-(R)-menthylamino-4-phenylamino-pyrrolin-2,5-dion (12) has been determined by X-ray crystallography. The pyrrolin-2,5-diones have been applied as planar, chiral N,N-ligands to modify the [Rh(COD)Cl](2) catalyst in the asymmetric hydrosilylation reaction of acetophenone. However, the optical induction observed for this reaction are poor for N,N-ligands as compared to the corresponding P,P-ligands.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 29968-78-3, you can contact me at any time and look forward to more communication. Quality Control of 4-Nitrophenylethylamine hydrochloride.

Polytriphenylamine Derivative and Carbon Nanotubes as Cathode Materials for High-Performance Polymer-Based Batteries

Composites of polytriphenylamine (PTPA), its novel derivative poly(4-carbamoyl-N,N-diphenylaniline-2,2,5,5-tetramethyl-pyrrolin-1-oxyl) (PTPA-PO), and multi-walled carbon nanotubes (CNTs) were synthesized by in situ polymerization. The characterization results showed that the CNTs were homogeneously distributed in the polymer matrix and formed a cross-linked conductive network. The electrical properties of PTPA/CNT composites were better than those of traditional acetylene black as conductive agents. Electrochemical tests showed that the initial specific discharge capacity of the PTPA/CNT composites was 107.6 mAh g(-1 )(theoretical capacity of PTPA is 109 mAh g(-1)). Furthermore, further research to increase the specific capacity demonstrated that the as-synthesized polytriphenylamine derivative, PTPA-PO, with a CNT cathode presented two well-defined plateaus and an enhanced discharge capacity of 139.3 mAh g(-1). Additionally, the PTPA-PO/CNT electrode showed superior cycling performance and remained above 90% of the initial capacity after 100 cycles. The enhanced electrochemical performance of PTPA-PO was due to its combination of the conducting polymer PTPA and free radical active site pendant PO, which increased its electrochemical reaction rate, and this composite is a promising material for high-performance polymer-based organic batteries.

De Novo Protocol for the Construction of Benzo[a]fluorenes via Nitrile/Alkene Activation

Unprecedented chemo- and regioselective synthesis of benzo[a]fluorenes and naphthamide-substituted benzo[a]fluorenes were constructed from the reaction of (E)-2-aroyl-3-(2-(arylalkynes/alkenes)aryl)acrylonitrile scaffolds under metal-free conditions via the activation of nitriles and alkenes, respectively. A tentative reaction mechanism was proposed for this homofunctionalization of nitriles. Control experiments showed that the reaction proceeds via selective nitrile or alkene protonation, depending upon the substrates. Additionally, we demonstrated an alternative expeditious route for the synthesis of disubstituted benzo[a]fluorenes in the presence of TfOH alone.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 29968-78-3, you can contact me at any time and look forward to more communication. Category: pyrrolines.

N-Benzyloxymalimide for an easy access to 5-alkyl-3-pyrrolin-2-ones: asymmetric synthesis of the mixed imide substructure of the potent immunosuppressant microcolin B

O-Benzyl-N-benzyloxymalimide 12 has been synthesized as a useful variant of the chiral building blocks 9. The advantage of the malimide 12 over 9 was demonstrated by mild and high-yielding reductive N-deprotection of N-benzyloxylactams 18a-i to give a series of (4R,5S)-5-alkyl-4-hydroxy-pyrrolidin-2-ones, which are key intermediates for the asymmetric synthesis of pyrrolidines, pyrrolizidines, and indolizidines, as well as beta-hydroxy gamma-amino acids. Lactam ent-11a has been applied to the synthesis of the mixed imide 25, a key intermediate for the total synthesis of microcolin B, which also demonstrated that lactam ent-11a or 11a can serve as a latent form of the 5-methyl-3-pyrrolin-2-one substructure of majusculamide D 4, deoxymajusculamide D, and the jamaicamides A-C.
