Direct C-H bond halogenation and pseudohalogenation of hydrocarbons mediated by high-valent 3d metal-oxo species

Late-stage direct functionalization of the C-H bond is synthetically desirable. Metalloenzymes having metal-oxo active sites are well known to selectively catalyze hydroxylation and halogenation reactions with high efficiency. This review highlights the recent developments in the field of direct C-H halogenation and pseudohalogenation reactions catalyzed by the functional models of metalloenzymes.

Combined mechanistic and genetic programming approach to modeling pilot NBR production: influence of feed compositions on rubber Mooney viscosity

Mooney viscosity is an essential parameter in quality control during the production of nitrile-butadiene rubber (NBR) by emulsion polymerization. A process model that could help understand the influence of feed compositions on the Mooney viscosity of NBR products is of vital importance for its intelligent manufacture. In this work, a process model comprised of a mechanistic model based on emulsion polymerization kinetics and a data-driven model derived from genetic programming (GP) for Mooney viscosity is developed to correlate the feed compositions (including impurities) and process conditions to Mooney viscosity of NBR products. The feed compositions are inputs of the mechanistic model to generate the number-, weight-averaged molecular weights (M-n, M-w) and branching degree (BRD) of NBR polymers. With these generated data, the GP model is used to output the optimal correlation for the Mooney viscosity of NBR. In a pilot NBR production, Mooney viscosity data of NBR predicted by the process model agree quite well with experimental values. Furthermore, the process model enables the analyses of the univariate and multivariate influence of feed compositions on NBR Mooney viscosity, and the variables include the contents of vinyl acetylene and dimer in 1,3-butadiene, as well as the mass flow rate of the chain transfer agent (CTA) in the process. Based on the results, it is recommended to control the content of vinyl acetylene in the 1,3-butadiene feed below 14 ppm and the content of dimer below 1100 ppm. This developed process model would help stabilize NBR viscosity for a better control of the product quality.

Effect of Li+ Affinity on Ionic Conductivities in Melt-Blended Nitrile Rubber/Polyether

Substituting flammable liquid electrolytes with solid polymer electrolytes (SPEs) presents a serious challenge in improving the safety of lithium-ion batteries. Even though SPEs are a safer choice, their ionic transport properties are still lower than those of their liquid counterparts (<10(-4) S.cm(-1) at room temperature). Here, we report the preparation of a blend of polymers used as SPEs in lithium-ion batteries. Composed of an elastomer, hydrogenated nitrile butadiene rubber (HNBR), and poly(ethylene oxide) (PEO), this blend combines the high conductivity of PEO and the stable properties of HNBR and shows better flexibility than a pristine PEO SPE. It is worth noting that the addition of HNBR, coupled with the intrinsic LiTFSI salt concentration, also reduces the crystallinity and melting temperature of typical PEO-LiTFSI SPEs; this also explains the higher ionic conductivity at low temperature (1.18 x 10(-4 )S.cm(-1) at 40 degrees C). Given these initial results, we may conclude that this polymer blend is a promising candidate as an SPE for all solid-state lithium-ion batteries.

Ionic liquid catalyzed Ritter reaction/Pd-catalyzed directed Ortho-arylation; facile access to diverse libraries of biaryl-amides from Aryl-nitriles

Diverse libraries of biaryl-amides bearing N-t-butyl and N-adamantyl groups were synthesized in two steps by the Ritter reaction of aryl-nitriles, using tBuOH and AdaOH as carbocation precursors, and employing [BMIM(SO3H)][OTf] (neat or with [BMIM][PF6] as co-solvent) or tetramethyl guanidinium-ILs [TMG][X] (X = CF3COO, EtOSO3) as dual catalyst/solvent, followed by a Pd-catalyzed directed regioselective ortho – C – H arylation of the Ritter amides with Ar-X (X = I, Cl). The feasibility to perform the two-steps in sequence is also demonstrated, and potential for recycling/reuse of the ILs is also shown. Preference for [Pd] coordination to the amide carbonyl versus amide nitrogen is borne out by DFT computations. (C) 2020 Elsevier Ltd. All rights reserved.

Volatile Organic Compounds (VOCs) of Endophytic Fungi Growing on Extracts of the Host, Horseradish (Armoracia rusticana)

The interaction between plant defensive metabolites and different plant-associated fungal species is of high interest to many disciplines. Volatile organic compounds (VOCs) are natural products that are easily evaporated under ambient conditions. They play a very important role in inter-species communication of microbes and their hosts. In this study, the VOCs produced by 43 different fungal isolates of endophytic and soil fungi during growth on horseradish root (Armoracia rusticana) extract or malt extract agar were examined, by using headspace-gas chromatography-mass spectrometry (headspace-GC-MS) and a high relative surface agar film as a medium. The proposed technique enabled sensitive detection of several typical VOCs (acetone, methyl acetate, methyl formate, ethyl acetate, methyl butanol isomers, styrene, beta-phellandrene), along with glucosinolate decomposition products, including allyl cyanide and allyl isothiocyanate and other sulfur-containing compounds-carbon disulfide, dimethyl sulfide. The VOC patterns of fungi belonging to Setophoma, Paraphoma, Plectosphaerella, Pyrenochaeta, Volutella, Cadophora, Notophoma, and Curvularia genera were described for the first time. The VOC pattern was significantly different among the isolates. The pattern was indicative of putative myrosinase activity for many tested isolates. On the other hand, endophytes and soil fungi as groups could not be separated by VOC pattern or intensity.

Copper-promoted cyanoalkylation/ring-expansion of vinylcyclopropanes with alpha-C-H bonds in alkylnitriles toward 3,4-dihydronaphthalenes

A copper-promoted oxidative cyanomethylation/ring-expansion of vinylcyclopropanes with alpha-C(sp(3))-H bonds in alkyl nitriles is established for the generation of 1-cyanoethylated 3,4-dihydronaphthalenes. This cyanomethylation/ring-expansion involves a radical pathway and proceeds via cyanomethyl radical formation, radical addition and ring-expansion. This ring-expansion strategy offers a highly atom-economical route for the construction of nitrile-containing 3,4-dihydronaphthalenes, which can be transformed into other useful products under simple conditions.

Palladium(ii)-catalyzed three-component tandem reactions: synthesis of multiply substituted quinolines

The three-component tandem reaction of 2-aminobenzonitriles, arylboronic acids and ketones allowing the synthesis of polysubstitution quinolines is reported. This strategy presents a practical, efficient, one-pot procedure that delivers functional quinolines in moderate to good yields with high functional group tolerance. To enrich the synthetic applications in accessing diverse quinolines, a new method for the introduction of halogen substituents into target products has been developed as well, which shows potential for further synthetic elaborations.

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

Palladium-catalyzed cyanation of aryl halides within situgenerated CN(-)from ClCF2H and NaNH2

An efficient Pd-catalyzed cyanation of aryl halides within situgenerated CN(-)anions is described. The CN(-)source stems from the quadruple cleavage of chlorodifluoromethane (ClCF2H) with sodium amide (NaNH2). This transformation features no requirement of a toxic CN source and avoids the problem of HCN generation associated with traditional methods. A series of aryl nitriles are obtained from aryl halides in good yields under mild reaction conditions.
