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.

Synthesis and NMR spectroscopic studies of optically active derivatives of gamma-aminobutenoic acids and 2-amino-pyrrolin-4-ones

An efficient method for the preparation of optically active derivatives of gamma -amino-butenoic acids and their cyclic derivatives, 2-amino-pyrrolin-4-ones, from alpha -amino acids is described. Partial racemization accompanies the formation of initial unsaturated gamma -amino- beta -hydroxy esters 5-8, as determined by chiral HPLC.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 96-54-8 is helpful to your research. Synthetic Route of 96-54-8.

Triarylborane catalysed N-alkylation of amines with aryl esters

The ability of halogenated triarylboranes to accept a lone pair of electrons from donor substrates renders them excellent Lewis acids which can be exploited as a powerful tool in organic synthesis. Tris(pentafluorophenyl)borane has successfully demonstrated its ability to act as a metal-free catalyst for an ever-increasing range of organic transformations. Herein we report the N-alkylation reactions of a wide variety of amine substrates including diarylamines, N-methylphenyl amines, and carbazoles with aryl esters using catalytic amounts of B(C6F5)(3). This mild reaction protocol gives access to N-alkylated products (35 examples) in good to excellent yields (up to 95%). The construction of a C-N bond at the propargylic position has also been demonstrated to yield synthetically useful propargyl amines. On the other hand, unsubstituted 1H-indoles and 1H-pyrroles at the C3/C2 positions afforded exclusively C-C coupled products. Extensive DFT studies have been employed to understand the mechanism for this transformation.

Simultaneous synthesis of thioesters and iron-sulfur clusters in water: two universal components of energy metabolism

Thioesters are important intermediates in both synthetic organic and biosynthetic reaction pathways. Here we show that thioesters can be synthesized in an aqueous reaction between thioacetate and thiols. The reaction can be coupled to a second reaction between sulfide and either ferrous or ferric iron, which drives the reaction forward. We furthermore demonstrate that sulfide released during thioester formation can be used in the synthesis of peptide bound [Fe-S] clusters, which like thioesters, are ancient components of metabolism. Together our results reveal a primordial linkage between high-energy ester formation and redox chemistry.

Organocatalyzed Asymmetric Mannich Reaction: An Update

The Mannich reaction is a multicomponent reaction resulting in aminoalkylation of an acidic proton placed next to a carbonyl functional group. It involves an appropriate carbonyl compound, such as formaldehyde and a primary or secondary amine or ammonia. The final product is a beta-amino-carbonyl compound known as a Mannich base. Reactions between aldimines and alpha-methylene carbonyls are also considered as Mannich reaction since these imines are generated from the reaction of amines and aldehydes. It comprises the reaction of primary or secondary amines or ammonia, formaldehyde and appropriate alpha-CH-acidic compounds (nucleophiles) such as carbonyl compounds having alpha-CH-acidic, nitriles, acetylenes, aliphatic nitro compounds, alpha-alkyl-pyridines or imines. Owing to the development of asymmetric organocatalysis, reports on asymmetric Mannich reaction have been drastically increased. The asymmetric Mannich reaction offers access to enantioenriched beta-amino ketones or beta-amino aldehydes, which are present as a scaffold in several natural products. Organocatalysts have been developed not only as a supplement to metal-catalyzed reactions or to biocatalysis, but nowadays, they are extensively used for the synthesis of various optically pure compounds that could not be achieved via metal- or biocatalyzed reactions. In this review, we try to update the advances in organocatalyzed asymmetric Mannich reactions, covering the recent advances of the subject from 2008 to date.

A new Ni(dmit)(2)-based organic magnetic charge-transfer (CT) salt, (m-PO-CONH-N-methylpyridinium)[Ni(dmit)(2)]center dot CH3CN, where PO = 2,2,5,5-Tetramethyl-3-pyrrolin-1-oxyl free radical and dmit = 2-Thioxo-1,3-dithiole- 4,5-dithiolate, was obtained, the crystal structure and magnetic properties of which are reported. Magnetic susceptibility of the CT salt obeys a combination of 1D ferromagnetic (1DF) Heisenberg (J(1DF) = +0.26 K) and Singlet-Triplet (ST) models (J(ST) = -51.2 K) with mean field (MF) approximation (J(MF) = -6.7 K), suggesting that spins on the PO radicals form 1D ferromagnetic chains and spins on the Ni (dmit)(2) monoanions form spin dimers at low temperature, the latter of which was also confirmed by band calculations.

alpha-(N-carbamoyl)alkylcuprate chemistry in the synthesis of nitrogen heterocycles

The conjugate adducts obtained via coupling of alpha-(N-carbamoyl)alkylcuprates with alpha,beta-ynoates, alpha-allenyl esters, or alpha,beta-enoates or enimides undergo N-Boc deprotection and cyclization onto the ester functionality upon treatment with PhOH/TMSCl, catecholboron bromide, or trimethylsilyl triflate. This two-pot sequence provides synthetic routes to 4-alkylidinepyrrolidine-2-ones, 4-alkylidinepyrrolizidin-2-ones, and 4-alkylidineindolizidin-2-ones via allenyl esters; pyrrolin-2-ones, tetrahydropyrrolizin-2-ones, and tetrahydroindolizin-2-ones via alpha,beta-ynoates; pyrrolidin-2-ones, pyrrolizidin-2-ones, and indolizidin-2-ones via alpha,beta-enoates or alpha,beta-enimides. The reluctance of gamma-carbamoyl-alpha,beta-enoates to undergo E/Z isomerization requires the use of (Z)-beta-iodo-alpha,beta-enoates readily prepared by the addition of HI to the alkynyl esters for the efficient preparation of pyrrolinones, tetrahydropyrrolizinones, and tetrahydroindolizinones. Utilization of omega-functionalized alpha,beta-ynoates or beta-iodo-alpha,beta-enoates allows for cyclization onto the omega-functionality providing for a synthetic route to quinolizidines.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 54663-78-4. Quality Control of Tributyl(thiophen-2-yl)stannane.

The structure assignment of 4a is confirmed on the basis of an X-ray crystal-structure determination. Similarly, diaryl azines 8a-c react with 1 through a formal [2 + 3] cycloaddition reaction to give the non-isolable product Delta(4)-pyrrolin-3-ones 10a-c which undergo oxidative rearrangement to afford ultimately the indenone derivatives 9a-c.
