A butterfly-shaped dinuclear Pt(II) complex having pyridyl-NHC chelate ligands and bridging Me(2)pz ligands was synthesized. The crystal structure of the Pt-2 complex showed short intramolecular Pt center dot center dot center dot Pt distance (3.129 angstrom) and unique packing structure containing one-dimensional infinite pore that was filled with solvent molecules. The absorbance was proportional to the concentration of Pt-2 complex and no significant bands appeared even in high concentration (up to 100 mu M). The Pt-2 complex showed bluish-green emission (lambda(max) = 459 nm) in the solid state at 298 K (lambda(ex) = 330 nm). TD-DFT calculation revealed that the lowest-energy absorption bands are mainly assigned to the combination of metal-to-ligand charge transfer (MLCT) and ligand-to-ligand charge transfer (LLCT) transitions.

Errors were discovered regarding the published equation coefficients of Yao and co-workers (2017) for mathematically describing the solubility of 3,5-dimethylpyrazole in nine organic solvents using the NRTL model. Larger differences were found between our back-calculated data and those reported in the authors’ published paper. The equation parameters were re-regressed based on the reported solubility data.

The synthesis and characterization of air-stable Cu(II) and Zn(II) complexes with 3,5-dinitrobenzoate (DNB) and 3,5-dimethylpyrazole (L1) or bis(3,5-dimethylpyrazol-1-yl)methane (L2) are described. Three of these complexes exhibit a monomeric structure, while the Cu(II) complex with L2 is a trinuclear complex. Density functional theory calculations were performed to understand the unexpected formation of the three-centered compound. In agreement with the X-ray crystal structure, the N-H moiety present in LI was identified as possible driving force to obtain monomeric structures, while L2, without it, can favor the trinuclear complex formation. Thermal studies were carried for the complexes, and it was observed that the presence of the azole ligand allows the decomposition of the complexes at lower temperatures due to the presence of acidic protons, being especially important for L1.

Multinuclear Ag clusters sandwiched by Pt complex units were synthesized and characterized by single crystal X-ray diffraction and NMR studies. The sandwich-shaped multinuclear Ag complexes showed two different types of fluxional behavior in solution: rapid slippage of Pt complex units on the Ag-3 core and a reversible demetalation-metalation reaction by the treatment with Cl anion and Ag ion, respectively. The Ag-2 complex obtained by demetalation reaction from the Ag-3 complex displayed U to Z isomerization. These multinuclear Ag complexes showed strong photoluminescence whose properties depended on the existence of Pt -> Ag dative bonds. The Ag-3 complex, identified to be chiral-at-cluster, was optically resolved by the formation of a diastereomeric salt with a chiral anion. The enantiomers show circular dichroism (CD) and circularly polarized luminescence (CPL) properties which is unprecedented for compounds based on a chiral sandwich structure. Theoretical calculations allow to understand their structural features and photophysical properties.

This study was aimed to identify volatile compounds of 31 green coffee bean samples and evalute their correlation with altitude of the coffee plants grown in two zones (Gedeo and Jimma) in Ethiopia. A total of 81 different compounds were detected. The contents of dominant volatile compounds in green coffee beans were in the range: trans-linalooloxide (3.24-19.13%), linalool (1.56-21.76%), 2-methoxy-4-vinylphenol (2.34-15.08%) and cis-linalooloxide (1.03-13.27%). In addition, benzene acetaldehyde (0.45-10.97%), 2-heptanol (0.67-8.49%), alpha-terpineol (0.64-6.52%), phenylethyl alcohol (0.44-4.98%) and furfural (0.92-5.3%) were the next dominant compounds. The volatile compounds identified in the green coffee beans are groups of alcohols, aldehydes, ketones, pyrazines, pyridines, and furans. The volatile compounds in green coffee beans showed either weak positive or weak negative correlation with the altitude of coffee plants indicating that variation in altitude of the coffee plants does not significantly influence the volative compounds of green coffee beans.

Existing methods for cleanup of wastewaters and soils polluted with the extremely toxic rocket fuel unsymmetrical dimethylhydrazine (UDMH) are mainly based on the treatment with various oxidative reagents. Until now, the assessment of their effectiveness was based on the residual content of UDMH and did not take into account the possibility of the formation of a large number of potentially dangerous nitrogen-containing transformation products (Ws). In this study, using the recently developed approach based on high-resolution Orbitrap mass spectrometry, the comprehensive characterization of UDMH TPs formed by the action of air oxygen and different oxidants (Fenton’s reagent, KMnO4, HOCl, H2O2 in the presence of Cu2+ and [Fe (EDTA)](-) catalysts) typically used to detoxify spill sites was performed. The range of the identified molecular formulas of TPs comprised 303 compounds of various classes. Among them, there is a number of major products not previously described in the literature. It was established that none of the investigated oxidative reagents ensures complete conversion of rocket fuel to safe compounds. The hydrogen peroxide based reagents, particularly H2O2 + Na [Fe (EDTA)] system currently used in Kazakhstan, give the greatest number of TPs, for many of which a toxicity was not characterized so far. The majority of the compounds found in model solutions was detected in extracts of soil from the crash site of the Proton carrier rocket, which was subjected to the on-site reagent treatment. During successive treatments, along with the decrease in the number of detectable UDMH TPs, their ratios change in favor of amines. (C) 2019 Elsevier Ltd. All rights reserved.

A series of organic dyes derived from s-tetrazine have been synthesized, and their photophysical and electrochemical properties are systematically investigated. Testing these compounds as photoredox catalysts in a model oxidative C-S bond cleavage of thioethers has led us to identify new classes of active s-tetrazines. Moreover, some of them can be formed in situ from commercially available 3,6-dichlorotetrazine, making this photocatalyzed C-S bond functionalization simple and highly practical.

New tri- and tetraalkyl-substituted o-benzoquinones were synthesized based on 5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene-2,3-diol derivatives. The new compounds were characterized by spectroscopic and electrochemical methods. The reactivity of o-benzoquinones was evaluated in the photoreduction and initiation of photopolymerization of oligocarbonate dimethacrylate (OCM-2) in the presence of N,N-dimethylcyclohexylamine and in the inhibition of MMA polymerization. The introduction of the methyl substituent into the benzene ring has a weak effect on the inhibitory activity of o-benzoquinone, whereas the (3,5-dimethylpyrazol-1-yl)methyl substituent enhances the inhibitory effect of 4,5-di-tert-alkyl-substituted o-benzoquinone.

Polycyclic N-oxides were developed based on the heterocycles 1,2,4,5-tetrazine and 4H, 8H-difurazano[3,4-b:3′,4′-e]pyrazine. The new compounds are energetic and have excellent explosive properties, while maintaining low mechanical sensitivities. Most notably, compound 7 is thermally stable, insensitive, and has superior detonation properties to the state-of-the-art insensitive high explosive, 1,3,5-triamino-2,4,6-trinitrobenzene.

A reaction of [Cu(MeCN)(4)]BF4 with PzH (3,5-dimethyl-pyrazole) and BINAP [2,20-bis(diphenylphosphino)-1,10-bi-naphthyl] leads to the formation of mononuclear Cu-I complex [Cu(PzH)(BINAP)]BF4 containing the molecule of non-deprotonated pyrazole and one BINAP ligand with two phosphorus atoms chelating the metal. This complex exhibits a bright phosphorescence originating from the (3)(M+L)LCT state at room temperature. At 77 K, the emission is splitted into two components: (3)(M+L)LCT and (LC)-L-3 transitions.
