Crystal melting and vitrification behaviors of a three-dimensional nitrile-based metal-organic framework

A three-dimensional (3D) metal-organic framework [Ag(pL2)(CF3SO3)]center dot 2C(6)H(6) (pL2 = 1,3,5-tris(4-cyanophenylethynyl)benzene), composed of Ag+ and tripodal nitrile ligands, was prepared to enable the investigation of its crystal melting and vitrification behaviors. The guest-free state showed a crystal melting at 271 degrees C, and the liquid state transformed into a glassy state via cooling. The vitrification of the crystalline compound into an amorphous glassy state was also obtained by mechanical hand-grinding. The structure of the glassy state retained the 3D networked structure, confirmed by FT-IR, X-ray absorption, and scattering measurements. The mechanically induced glass showed a small uptake of CO2 and a strong affinity for benzene and H2O vapors, confirmed by gas sorption isotherms. Powder X-ray diffraction studies have revealed that the vitrified structure returned to the original 3D crystalline structure by exposure to these vapors.

A Comprehensive Study about the Role of Crosslink Density on the Tribological Behavior of DLC Coated Rubber

The friction and wear behavior of coated rubber components is strongly dependent on the substrate properties. This work deals with the impact of the crosslink density, i.e., the hardness of the rubber substrate on the tribological performance of uncoated and coated rubber. The hardness of nitrile butadiene rubber (NBR) is varied altering the sulfur content. Both the uncoated and coated rubber samples are characterized in terms of surface and mechanical properties. Tribological tests comprise the examination of the macroscopic contact area and the temperature in the contact zone. It was found that the functional layer enhances the wear resistance significantly. Apparently, the wear and friction behavior of the coated rubber correlates with the hardness and the bulk properties of the substrate material.

A Lewis Base Supported Terminal Uranium Phosphinidene Metallocene

A Lewis base supported terminal uranium phosphinidene, [eta(5)-1,3-(Me3C)(2)C5H3]2U(= P-2,4,6-(Bu3C6H2)-Bu-t)(OPMe3) (5), is isolated from the reaction of the uranium methyl chloride [eta(5)- 1,3-(Me3C)(2)C5H3](2)U(Cl) Me (4) with 2, 4, 6-(Me3C)(3)C6H2PHK in toluene in the presence of Me3PO. Moreover, the reactivity of uranium phospinidene 5 toward a series of small molecules was comprehensively explored. While no reactivity of 5 with internal alkynes is observed attributed to steric hindrance, it readily reacts in good yields with various small molecules including isothiocyanates, aldehydes, imines, diazenes, carbodiimides, nitriles, isonitriles, and organic azides, yielding uranium sulfidos, oxidos, metallaheterocycles, and imido complexes.

Hepatotoxicity of Two Progoitrin-Derived Nitriles in New Zealand White Rabbits

Cattle occasionally develop brassica-associated liver disease (BALD) and photosensitisation when grazing turnip or swede (Brassica spp.) forage crops. The liver toxin in these brassica varieties has yet to be discovered. Progoitrin is the dominant glucosinolate in incriminated crops. Apart from goitrin, progoitrin hydrolysis yields the nitrile, 1-cyano-2-hydroxy-3-butene (CHB), and the epithionitrile, 1-cyano-2-hydroxy-3,4-epithiobutane (CHEB). The two compounds were custom-synthesised. In a small pilot trial, New Zealand White rabbits were given either CHB or CHEB by gavage. Single doses of 0.75 mmol/kg of CHB or 0.25 mmol/kg of CHEB were subtoxic and elicited subclinical effects. Higher doses were severely hepatotoxic, causing periportal to massive hepatic necrosis associated with markedly elevated serum liver biomarkers often resulting in severe illness or death within 24 h. The possibility that one or both of these hepatotoxic nitriles causes BALD in cattle requires further investigation.

Mechanistic insights into the Rh(i)-catalyzed transannulation of 1,2,3-thiadiazoles with alkenes, alkynes, and nitriles: Does the intermediacy of alpha-thiavinyl Rh-carbenoids play an important role?

Density functional theory (DFT) calculations were performed to gain an in-depth mechanistic understanding of the Rh(i)-catalyzed transannulation of 1,2,3-thiadiazoles with alkenes, alkynes, and nitriles. Computational results indicate that the denitrogenation of 1,2,3-thiadiazoles promoted by the Rh(i) catalyst may not afford the commonly proposed alpha-thiavinyl Rh-carbenoid intermediate. Instead, the four-membered cyclometalated Rh(iii) complex is suggested to be the key intermediate, which could be formed via the cleavage of the S-N bond of 1,2,3-thiadiazoles to generate a six-membered cyclometalated Rh(iii) complex followed by N-2 extrusion. The easy chelation of the S atom with Rh is mainly responsible for the favorable formation of the four-membered cyclometalated Rh(iii) intermediate. Next, the substrates alkenes, alkynes, and nitriles could undergo migratory insertion with the four-membered rhodacycle followed by reductive elimination to furnish the corresponding products. The origins of divergent regioselectivities for the Rh(i)-catalyzed transannulation of 1,2,3-thiadiazoles with alkenes, alkynes, and nitriles are discussed, respectively, which are not only determined by the feasible migratory insertion pathway, but also by the feasibility of the subsequent reductive elimination.

Copper-catalyzed radical oxidative C(sp(3))-H/C(sp(3))-H cross-coupling between arylacetonitriles and benzylic compounds

For the first time, a novel copper-catalyzed direct C(sp(3))-H/C(sp(3))-H cross-coupling of arylacetonitriles with unactivated benzylic compounds was described, allowing various a-benzylated arylacetonitriles to be readily accessible under base-free conditions. Mechanistic investigations suggested that the reaction proceeds through radical process and the C(sp(3))-H cleavage of arylacetonitriles probably is the rate-determining step. (C) 2020 Elsevier Ltd.

Influence of oligomeric unsaturated polyketone on the vulcanization of elastomeric compositions in the presence of sulfenamide C

Effect of the oligomeric unsaturated polyketone (UPK) additive on the rheological properties, vulcanization, and structural characteristics of elastomeric compositions based on butadiene and nitrile-butadiene rubbers containing N-cyclohexyl-2-benzothiazolylsulfenamide (sulfenamide C) as vulcanizing accelerator is investigated. It was demonstrated using IR and NMR spectroscopy that sulfenamide C reacts with polyketone. A mechanism for such interaction, which includes the sequential addition of benzothiazyl sulfide and amine fragments to the oligomeric chain, was proposed.

Nitriles as radical acceptors in radical cascade reactions

The cyano group is a valuable and readily available functional group for the preparation of various functional groups, such as amines, carboxylic acids, and ketones. In recent decades, the radical cascade reaction has emerged as a versatile tool to prepare a large variety of functional molecules. The application of the cyano group as a radical acceptor in cascade reactions provides diverse opportunities for the convenient construction of various important heterocycles and carbocycles.
