The purpose of this study was to examine the effects of silane coupling agent modifications on the mechanical performance of the basalt fiber (BF)-reinforced acrylonitrile-butadiene-styrene (ABS) composites. Three different silane coupling agents were used. The mechanical properties of the composites were determined by the tensile, flexural, impact tests, and dynamic mechanical analysis (DMA). According to the test results, the tensile strength increased with the use of (3-aminopropyl) triethoxysilane (AP) and 3-(trimethoxysilyl) propylmethacrylate (MA), while the use of (3-glycidyloxypropyl) trimethoxysilane (GP) reduced the tensile strength. All the silane modifications improved the flexural strength and modulus and the highest improvement was achieved with the use of AP. No remarkable difference was observed in impact properties with the use of silane coupling agents. The addition of BF significantly improved the elastic modulus of the ABS regardless of the modification type, while the further improvements were achieved through the use of AP and MA. In brief, AP showed the highest performance among the studied silane coupling agents due to the covalent bond formation between the amino group of AP and the nitrile group of styrene-acrylonitrile (SAN) matrix.

Synthesis of Cyanoalkynes from Alkyne Bromide and CuCN

A direct generation of cyanoalkynes from alkyne bromide and CuCN was reported. Mild reaction conditions were required, using catalytical amount of KI as the additive and DMSO as the solvent under 60 degrees C. GC analysis showed that alkyne iodide may be the intermediate. Both aromatic ethynyl bromides and aliphatic ethynyl bromides were proved to be good substrates. Good isolated yield was also observed in 10 gram scale synthesis. This method has provided an important alternative synthetic route to cyanoalkyne structures.

1,3-Dipolar cycloaddition reactions of acyl phosphonates with nitrile oxides: synthesis of phosphonate-containing dioxazole derivatives

New phosphonate-containing five-membered heterocyclic dioxazole derivatives are synthesized via 1,3-dipolar cycloaddition reactions of nitrile oxides used as dipole with acyl phosphonates under basic conditions. Herein, acyl phosphonates take part in the cyclization process as a dipolarophile to afford the related dioxazole compounds in moderate-to-good yields (49-84%). Substituted aryl nitrile oxides and aroyl phosphonates were employed in the 1,3-dipolar cycloaddition reactions where triethylamine was the effective tertiary base. Alkyl version of acyl phosphonate also afforded the expected cycloadduct, that is, dimethyl 5-isopropyl-3-phenyl-1,4,2-dioxazol-5-yl-5-phosphonate. Diethyl/dimethyl 3,5-aryl-1,4,2-dioxazol-5-yl-5-phosphonate derivatives are fully characterized by using H-1 NMR, C-13 NMR, P-31-NMR, and FT along with high-resolution mass spectroscopy.

Oxalohydrazide Ligands for Copper-Catalyzed C-O Coupling Reactions with High Turnover Numbers

Here, we report a class of ligands based on oxalohydrazide cores and N-amino pyrrole and N-amino indole units that generates long-lived copper catalysts for couplings that form the C-O bonds in biaryl ethers. These Cu-catalyzed coupling of phenols with aryl bromides occurred with turnovers up to 8000, a value which is nearly two orders of magnitude higher than those of prior couplings to form biaryl ethers and nearly an order of magnitude higher than those of any prior copper-catalyzed coupling of aryl bromides and chlorides. This ligand also led to copper systems that catalyze the coupling of aryl chlorides with phenols and the coupling of aryl bromides and iodides with primary benzylic and aliphatic alcohols. A wide variety of functional groups including nitriles, halides, ethers, ketones, amines, esters, amides, vinylarenes, alcohols and boronic acid esters were tolerated, and reactions occurred with aryl bromides in pharmaceutically related structures.

Synthesis of Fused Six-Membered Lactams to Isoxazole and Isoxazoline by Sequential Ugi Four-Component Reaction and Intramolecular Nitrile Oxide Cyclization

The advanced organic chemistry experiments describe the preparation of fused six-membered lactams to isoxazole and isoxazoline by employing Ugi four-component reaction (U-4CR) and intramolecular nitrile oxide cyclization (INOC) synthetic sequence. The experiments were carried out in 28 h (overnight for U-4CR) and 2 h (for INOC) using commercially available starting materials. The two-step reaction involves the in situ imine formation in the one-pot multicomponent reaction and in situ nitrile oxide formation in the INOC. The experiments are useful in the organic chemistry curriculum for the introduction of a onepot multicomponent reaction and 1,3-dipolar cycloaddition reactions.

Prebiotic synthesis of cysteine peptides that catalyze peptide ligation in neutral water

Peptide biosynthesis is performed by ribosomes and several other classes of enzymes, but a simple chemical synthesis may have created the first peptides at the origins of life. alpha-Aminonitriles-prebiotic alpha-amino acid precursors-are generally produced by Strecker reactions. However, cysteine’s aminothiol is incompatible with nitriles. Consequently, cysteine nitrile is not stable, and cysteine has been proposed to be a product of evolution, not prebiotic chemistry. We now report a high-yielding, prebiotic synthesis of cysteine peptides. Our biomimetic pathway converts serine to cysteine by nitrile-activated dehydroalanine synthesis. We also demonstrate that N-acylcysteines catalyze peptide ligation, directly coupling kinetically stable-but energy-rich-alpha-amidonitriles to proteinogenic amines. This rare example of selective and efficient organocatalysis in water implicates cysteine as both catalyst and precursor in prebiotic peptide synthesis.

A theoretical investigation of iron-catalyzed selective hydrogenation of nitriles to secondary imines

The mechanism of the transition metal iron complex [(iPr-PNP)Fe(H)Br(CO)] catalyzed reaction of selective hydrogenation of nitriles to secondary imines has been investigated with the M06-2X function. The results indicate that the reaction involves two basic processes: (i) A catalyzed p-bromobenzonitrile to benzaldimine and primary amine transformation; (ii) condensation of benzaldimine with a primary amine to afford secondary imine. The calculated barrier of transition metal-catalyzed condensation reaction of benzaldimine with a primary amine, 30.6 kcal/mol, indicates that the condensation reaction is feasible under experiment conditions. The theoretical results provide a deeper understanding of the mechanism and fully explain the experimental facts.

Characterization of Dielectric Relaxation Process by Impedance Spectroscopy for Polymers: Nitrile Butadiene Rubber and Ethylene Propylene Diene Monomer

We invented a dispersion analysis program that analyzes the relaxation processes from dielectric permittivity based on a combination of the Havriliak-Negami and conductivity contribution functions. By applying the created program to polymers such as nitrile butadiene rubber (NBR) and ethylene propylene diene monomer (EPDM), several relaxation processes were characterized: an alpha process due to segmental motions of the C-C bond, an alpha ‘ process attributed to fluctuations in the end-to-end dipole vector of the polymer chain, the conduction contribution by the filler observed above room temperature, and secondary relaxation processes beta and gamma of motion for the side group in NBR. In the EPDM specimen, the beta process associated with the rotational motion of the side groups, the alpha process associated with the relaxation of local segmental motion, and the alpha beta process associated with the origin of the beta process at high temperatures above 305 K were observed. The Maxwell-Wagner-Sillars effect and conduction contribution were also presented. The molecular chains responsible for the relaxation processes were assigned by building molecular models of the two polymers. The temperature dependence of the relaxation strength and the shape parameters that characterize the process were investigated. From the temperature-dependent relaxation analysis, the merged alpha beta process, activation energy, and glass transition temperature were determined and compared.
