Two copper(II) complexes with benzotriazole-based ligands having pyridyl and quinolinyl arms were synthesized in good yields and characterized fully via spectroscopic and crystallographic techniques. The crystal structures of the complexes revealed different coordination environments around copper(II) centers. The difference in structure was due to the steric effect of the ligands, which resulted in an octahedral and a square pyramidal geometry of the resulting complexes in the solid state. Both the air-stable complexes were utilized as precatalysts in catalytic click reactions and A(3) coupling.

An economical and efficient method has been developed for the production of dibarbiturates of oxindole and arylidene barbituric acid derivatives via condensation of of isatin/aryl aldehyde with barbituric acid, through irradiation of visible light. Under the similar conditions 2 molecules of barbituric acid react with 1 molecule of isatin while only 1 molecule of barbituric acid reacts with 1 molecule of aldehyde. This transformation involves catalyst free pathway for the formation of desired products under mild reaction conditions. Metal free reaction conditions, high yield of products along with the absence of side-products are additional green features of this protocol.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

Synthesis and characterization of novel coumarins containing carborane units were described. The breakdown reactions of cyclic oxonium derivatives of cobalt bis (1,2-dicarbollide) and closo-dodecaborate anions with a series of 7-hydroxy-3-substituted coumarins led to conjugates attached via C-7 position of the coumarin unit. The corresponding reactions of cobalt bis (1,2-dicarbollide) anion with 3-(4-hydroxybenzoyl)-7-methoxy-2H-chromen-2-one led to conjugates attached via C-3 position. Novel conjugates were isolated in the form of alkali metal salts. Therefore, these conjugates are of interest for the fluorescent study in aqua media. (C) 2020 Elsevier B.V. All rights reserved.

Sequence-controlled polymerization is the forefront of polymer chemistry. Herein, the feasibility of sequence regulation by using organocatalyzed ring-opening polymerization (ROP) is demonstrated. In particular, ring expansion strategy is employed to synthesize pre-organized monomers 1 and 2. ROP is conducted by using 1,5,7-triazabicyclo[4.4.0]dec-5-ene and benzyl alcohol as the catalyst and initiator, respectively. Poly(ester amide)s (PEAs) P1-P3 comprising glycolic acid, lactic acid, and 7-aminoheptanoic acid units are obtained in high molecular weights and good yields. NMR and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry results verify the microstructural integrity of P1 and P2. Differential scanning calorimetry results show that PEA without methyl branches is crystalline. Moreover, thermal stability, surface wettability, and degradation profiles of P1-P3 are also investigated.

Effects of three carp species on texture, color, and aroma properties of Chinese traditional fermented freshwater fish (Suan yu) were investigated. Suan yu were produced from Ctenopharyngodon idella (Grass Carp, GC), Hypophthalmichthys molitrix (Silver Carp, SC), and Cyprinus carpio (Common Carp, CC) as the control. GC displayed the highest hardness and resilience, while SC showed the lowest texture except for springiness (p < .05). GC had the greatest L* and Delta E* values but the least a* value (p < .05). Esters (7), alcohols (7), acids (9), aldehydes (8), ketones (1), hydrocarbons (4), and others (5) were identified by GC-MS in all samples. E-nose analysis showed a remarkable difference in the overall aroma profile among all samples. Sensory evaluation and PCA analysis indicated that grass carp could be used as an alternative raw material for Suan yu production, which would improve the utilization of freshwater fish. Practical applications Suan yu is a type of Chinese traditional fermented freshwater fish with a unique flavor, which is popular among consumers. Such products are commonly manufactured from fresh common carp (Cyprinus carpio) with long-term anaerobic fermentation. Grass carp (Ctenopharyngodon idella) and silver carp (Hypophthalmichthys molitrix) are popular among consumers as major domesticated fish in China with higher annual harvests than that of common carp, which show potential as raw materials for Suan yu production. It is the first time to investigate the texture, color, and aroma of Suan yu produced from the three carp species (grass carp, silver carp, and common carp) in the same process and to evaluate their quality differences and acceptability. This will help increase the sources of raw materials for Suan yu production and improve the utilization of freshwater fish. Quality Control of Benzyl Alcohol.

Bimetallic Cu@Ag core-shell nanoparticles (NPs) were synthesized by the reduction of copper 2-[2-(2-methoxyethoxy)ethoxy]acetate with hydrazine hydrate in benzyl alcohol followed by the reduction of silver ions on the copper surface using a galvanic replacement reaction. Ink consisting of the assynthesized Cu@Ag NPs dispersed in a mixture of nontoxic solvents with different boiling temperatures (butanol and propylene glycol ethers) was prepared. Thin layers were spin coated on polyimide films using the developed ink. The conductive layer formed in air in the optimized conditions showed an electrical resistivity of 28.5 mu Omega.cm.
