Revisiting the synthesis of aryl nitriles: a pivotal role of CAN

Facilitated by the dual role of Ceric Ammonium Nitrate (CAN), herein we report a cost-effective approach for the cyanation of aryl iodides/bromides with CAN-DMF as an addition to the existing pool of combined cyanation sources. In addition to being an oxidant, CAN acts as a source of nitrogen in our protocol. The reaction is catalyzed by a readily available Cu(ii) salt and the ability of CAN to generate ammonia in the reaction medium is utilized to eliminate the additional requirement of a nitrogen source, ligand, additive or toxic reagents. The mechanistic study suggests an evolution of CN- leading to the synthesis of a variety of aryl nitriles in moderate to good yields. The proposed mechanism is supported by a series of control reactions and labeling experiments.

Hydrothermal alkaline conversion of actual acrylonitrile wastewater to organic acids

Acrylonitrile wastewater is a kind of highly toxic industrial wastewater, but it contains a lot of valuable chemical materials. In this study, by using the most promising hydrothermal technology, we investigated the best reaction conditions and possible reaction pathways for the conversion of the three nitrites (acrylonitrile, acetonitrile, and succinonitrile) to organic acids under alkaline hydrothermal conditions. Then, the reaction conditions for the conversion of actual acrylonitrile wastewater to organic acids were further optimized. The actual wastewater of acrylonitrile was converted into 1.33 x 10(4) mg/L acrylic acid, 1.98 x 10(4) mg/L formic acid and 9.40 x 10(3) mg/L acetic acid at optimal reaction conditions (reaction temperature 300 degrees C, reaction time 90 s, and initial NaOH concentration 1.0 mol/L). It is the theoretical basis of the application of the hydrothermal alkali-catalyzed method in the acrylonitrile wastewater resource engineering.

Blooming-forming cyanobacteria pyrolysis over Ni-Al layered double oxides/MCM-41 for nitriles under nitrogen and methanol atmosphere

Blooming-forming cyanobacteria were catalytically pyrolyzed over Ni-Al layered double oxides/MCM-41 (NiAl-LDO/MCM-41) composites with nitrogen or methanol as sweep gas for the production of nitrogenous compounds. The effect of catalysts and gas atmosphere on the product distribution and the formation of nitrogenous compounds was investigated. The results showed that the amount of nitrogenous compounds increased with the increase of catalyst/cyanobacteria ratio; liquid yields of about 50% were obtained over NiAl-LDO/MCM-41 under both nitrogen and methanol atmosphere. However, composites of the hydrocarbons and aromatic compounds in bio-oil under methanol atmosphere were lower than those under nitrogen atmosphere. Nitrogenous compound content of 78.6%, especially a 68.5% content of nitriles with low oxygen content and acidity, demonstrated that the bio-oil obtained was promising in producing value-added platform chemicals.

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. Such synthetic strategies will open new ways for the rapid buildup of molecular complexity. The focus of this review is the summary of the dynamic field of radical cascade processes using the cyano group as a radical acceptor, which has not been well documented so far.

Ligand-controlled self-assembly of Ag(I) complexes with cyano-containing ligands and their tunable antimicrobial activities

Three cyano-containing ligands with varied size and shape, i.e. 1,4-dicyano benzene (1,4-dcb), 4,4′-biphenyldicarbonitrile (bpcn) and p-phenylenediacetonitrile (p-phda), were selected as ligands to self-assemble with AgCF3COO and 4,4′-dihydroxyoctafluorobipheny (ofbp) affording five new compounds. Complexes 1-3 ([Ag-2(CF3COO)2(1,4-dcb)(S)]center dot 2ofbp center dot H2O, 1, S=benzene, 2, S=toluene 3, S= m-xylene) were synthesized by the same linear spacer (1,4-dcb) in different solvents, and they exhibit similar 2D networks assembled by 1,4-dcb ligand bridging with 1D chains composing of anions and different coordinating solvents. Complex 4 ([Ag-2(CF3COO)(2)(bpcn)(2)]center dot C6H6 center dot 2ofbp center dot H2O) was isolated by replacing 1,4-dcb to the longer linear spacer (bpcn) however it shows a quite different 1D chain structure from those of 1-3. Further changing ligand to p-phda resulted only compound c as a co-crystal of p-phda and of bp. These totally different crystal structures suggest the ligand-controlled self-assembly processes. The followed antimicrobial assay results demonstrate that all complexes have effective antimicrobial activities with broad spectra. They exhibit excellent antimicrobial activities with low MICs towards both Gram-negative bacteria, Gram-positive bacteria and yeast. Especially, they illustrate encouraging antibacterial activities against antibiotic resistant bacteria (P. aeruginosa). It’s found that these frameworks have discriminating capacities to release Ag+ ions in water sustainably. Complex 4 demonstrated the best antimicrobial efficacy among five complexes. It’s revealed that the ligand exchangeability plays an important role in the anti-microbial activities. The lower concentration of Ag+ ions release of complex 3 is attributed to its compact packing structure on the basis of structure-property discussions.

In Situ Construction of Uniform and Robust Cathode-Electrolyte Interphase for Li-Rich Layered Oxides

High-energy-density Li-rich layered oxides (LLOs) as promising cathodes for Li-ion batteries suffer from the dissolution of transition metals (especially manganese) and severe side reactions in conventional electrolytes, which greatly deteriorate their electrochemical performance. Herein, an in situ anchoring + pouring synergistic cathode-electrolyte interphase (CEI) construction is realized by using 1,3,6-hexanetricarbonitrile (HTCN) and tris(trimethylsilyl) phosphate (TMSP) electrolyte additives to alleviate the challenges of an LLO (Li1.13Mn0.517Ni0.256Co0.097O2). HTCN with three nitrile groups can tightly anchor transition metals by coordinative interaction to form the CEI framework, and TMSP will electrochemically decompose to reshape the CEI layer. The uniform and robust in situ constructed CEI layer can suppress the transition metal dissolution, shield the cathode against diverse side reactions, and significantly improve the overall electrochemical performance of the cathod with a discharge voltage decay of only 0.5 mV cycle(-1). Further investigations based on a series of experimental techniques and theoretical calculations have revealed the composition of in situ constructed CEI layers and their distribution, including the enhanced HTCN anchoring effect after lattice densification of LLOs. This study provides insights into the in situ CEI construction for enhancing the performance of high-energy and high-voltage cathode materials through effective, convenient, and economical electrolyte approaches.

Strengthening effect of mullins effect under tearing mode and its reversibility for zinc dimethacrylate-reinforced thermoplastic vulcanizates based on ethylene-acrylic acid copolymer/nitrile-butadiene rubber blends

Thermoplastic vulcanizates (TPVs) based on ethylene-acrylic acid copolymer (EAA)/nitrile-butadiene rubber (NBR) and zinc dimethacrylate (ZDMA) reinforced EAA/NBR blends were prepared by dynamical vulcanization, the mechanical properties and Mullins effect of the TPVs under tearing mode were investigated systematically. Experimental results indicated that the increasing EAA dosage in the EAA/NBR TPVs and the incorporation of ZDMA in NBR phase of TPVs could all lead to the increase of tear strength. The Mullins effect of EAA/NBR and EAA/NBR/ZDMA TPVs could be observed obviously under tearing mode, while it was hardly to obverse in that of static NBR vulcanizate during the cyclic deformation.
