Synthesis and Catalytic Applications of Multinuclear Gold(I)-1,2,3-Triazolylidene Complexes

A series of mono- to trinuclear gold(I) complexes (1-3) supported by oxo-functionalized 1,2,3-triazolylidenes have been prepared. All new compounds were fully characterized by means of H-1 and C-13 NMR spectroscopy, elemental analyses, and in the case of complexes 1 and 2 by x-ray diffraction. The catalytic performance of the new triazolylidene gold complexes was tested in several hydroelementation and cyclization processes employing a variety of alkynes as starting materials. According to the overall results, the trinuclear complex 3 displayed the highest catalytic activity in all processes, providing good to excellent yields under mild reaction conditions.

Efficient photorelease of carbon monoxide from a luminescent tricarbonyl rhenium(I) complex incorporating pyridyl-1,2,4-triazole and phosphine ligands

Precise control over the production of carbon monoxide (CO) is essential to exploit the therapeutic potential of this molecule. The development of photoactive CO-releasing molecules (PhotoCORMs) is therefore a promising route for future clinical applications. Herein, a tricarbonyl-rhenium(I) complex (1-TPP), which incorporates a phosphine moiety as ancilliary ligand for boosting the photochemical reactivity, and a pyridyltriazole bidentate ligand with appended 2-phenylbenzoxazole moiety for the purpose of photoluminescence, was synthesized and characterized from a chemical and crystallographic point of view. Upon irradiation in the near-UV range, complex 1-TPP underwent fast photoreaction, which was monitored through changes of the UV-vis absorption and phosphorescence spectra. The photoproducts (i.e. the dicarbonyl solvento complex 2 and one CO molecule) were identified using FTIR, H-1 NMR and HRMS. The results were interpreted on the basis of DFT/TD-DFT calculations. The effective photochemical release of CO associated with clear optical variations (the emitted light passed from green to orange-red) could make 1-TPP the prototype of new photochemically-active agents, potentially useful for integration in photoCORM materials.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 464-48-2, you can contact me at any time and look forward to more communication. COA of Formula: C10H16O.

Pesticides and their degradates in groundwater reflect past use and current management strategies, Long Island, New York, USA

Long Island, New York, has a mix of urban/suburban to agricultural/horticultural land use and nearly 3 million residents that rely on a sole-source aquifer for drinking water. The analysis of shallow groundwater (<40 m below land surface) collected from 54 monitoring wells across Long Island detected 53 pesticides or pesticide degradates. Maximum concentrations for individual pesticides or pesticide degradates ranged from 3 to 368,000 ng/L. The highest concentrations andmost frequent pesticide detections occurred in samples collected from the pesticide management (PM) network, set in an agricultural/horticultural area in eastern Long Island with coordinated pesticide management by state and local agencies. The other two networks (Suffolk and Nassau/Queens) were set in suburban and urban areas, respectively, and had less frequent detections and lower pesticide concentrations than the PMnetwork. Pesticide detections and concentration patterns (herbicide, insecticide, or fungicide) differed among the three networks revealing broad differences in land use. The predominance of fungicides metalaxyl, 1H-1,2,4-triazole (propiconazole/myclobutanil degradate), and 4-hydroxychlorothalonil (HCTL, chlorothalonil degradate) in samples from the PM network reflects their intensive use in agricultural settings. Total fungicide concentrations in the PM network ranged from <10 to >300,000 ng/L. Thewidespread detection of imidacloprid and triazine herbicides, simazine and atrazine, reveal a mixture of current and past use pesticides across the Long Island region. Low concentrations (<200 ng/L) of the triazines in the Suffolk and Nassau/Queens networks may reflect a change in land use and application. Acetanilide herbicides and aldicarb have been discontinued for 20 and 40 years, respectively, yet the concentrations of their degradates were among the highest observed in this study. Acetanilide (total concentrations up to 10,000 ng/L) and aldicarb degradates (up to 270 ng/L) are present in the PM network at much lower concentrations than previous Long Island studies and reflect changes in agricultural practices and pesticide management.

Corrosion Inhibition Effect of Ethyl 1-(4-chlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylate on Aluminium Alloy in Hydrochloric Acid

The inhibition efficiency of Ethyl 1-(4-chlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylate (ETC) on AA6061 Aluminium (Al) alloy in 0.1M HCl solution was tested through weight loss, potentiodynamic polarisation and electrochemical impedance spectroscopy methods. The experimental results show that the inhibition efficiency of ETC increased with an increase in inhibitors concentration and temperature. Potentiodynamic polarisation indicated that the inhibitor is mixed type. From Langmuir isotherm, it was hypothesized the adsorption of inhibitors on AA6061 alloy surface might occur by physical and chemical interaction; however, the activation energy raised suggests a chemisorption process for the interaction of the inhibitor on AA6061 alloy surface. Scanning electron microscopy was used to characterise the surface morphology of the alloy in presence and in the absence of the inhibitor.

The present paper is devoted to the search for drug-like molecules with anticancer properties using the thiazolo[3,2-b][1,2,4]triazole-6-one scaffold. A series of 24 novel thiazolo-[3,2-b][1,2,4]triazole-6-ones with 5-aryl(heteryl)idene- and 5-aminomethylidene-moieties has been synthesized employing three-component and three-stage synthetic protocols. A mixture of Z/E-isomers was obtained in solution for the synthesized 5-aminomethylidene-thiazolo[3,2-b]-[1,2,4]triazole-6-ones. The compounds have been studied for their antitumor activity in the NCI 60 lines screen. Some compounds present excellent anticancer properties at 10 mu M. Derivatives 2h and 2i were the most active against cancer cell lines without causing toxicity to normal somatic (HEK293) cells. A preliminary SAR study had been performed for the synthesized compounds.

Ecological consequences of space rocket accidents in Kazakhstan between 1999 and 2018

In this paper, we briefly described the ecological consequences of six space rocket accidents launched from the Baikonur Cosmodrome between 1999 and 2018 and focused on an assessment of efficiency of soil remediation following the accidental crash of launch vehicle Proton-M on July 2, 2013, which resulted in the severest environmental impact in the modern Russian space industry. On the day after the accident, the content of carcinogenic unsymmetrical dimethylhydrazine and nitrosodimethylamine, as well as nitrate in soils of the crash site exceeded their maximal permissible concentrations by 8900, 6100 and 85 times, respectively. Mitigation measures included soil detoxication by a solution of 10% H2O2 and 1% iron complexonate, soil excavation and ploughing. Two years later (in April 2015), both unsymmetrical dimethylhydrazine and nitrosodimethylamine concentrations were below 0.05 mg/kg and nitrate concentration did not exceed 3.9 g/kg. As compared to background sites, soils of the crash site had significantly (P-value<0.05) lower values of pH and the content of total organic carbon, basicity from soda and carbonates and higher total nitrogen and soluble salt contents. Soil microbial communities were the most vulnerable component of the disturbed arid ecosystems, as their suppressed condition was indicated by a low biochemical oxygen demand and a very low cellulase activity.

Flame-retardant, phosphorous-based polyurethane triazoles via solvent-free and catalyst-free azide-alkyne cycloaddition and their cure kinetics

A novel class of phosphorous-containing polyurethane triazoles (PUTs) with self-extinguishing property is reported. Initially, a set of new urethane diazide monomers were synthesized by reacting diisocyanates (DI) (isophorone (IPDI), hexamethylene (HDI), and toluene (TDI)) with 2-azidoethanol and characterized by FTIR, H-1 NMR, C-13 NMR, and ESI-MS analysis. Later, the corresponding PUTs were synthesized via azide-alkyne cycloaddition of urethane diazides with triprop-2-ynyl phosphate under solvent-free and catalyst-free conditions at 80 degrees C via thermal polymerization. Cure kinetic study of the thermally induced polymerization of PUTs was performed to correlate with isocyanate functionality. The activation energies (Ea) of the PUTs derived from nonisothermal multiheating rate DSC tests were fitted to Borchardt-Daniels model. The Ea’s were found to be proportional to heating rates for all PUTs and confirmed optimum percentage conversion at lower heating rates. The experimental findings were found to corroborate well with Borchardt-Daniels model. The PUTs were characterized by FTIR, TGA, DSC, MCC, LOI, lab-scale flame tests, and EDX analysis. All PUTs were self-extinguishable, but TD-PUT with aromatic functionality (TDI-based) demonstrated superior extinguishing performance with lowest total heat release (6.11 kJ/g), peak heat release rate (42.04 W/g), heat release capacity (85.59 J/g K), and 31% LOI comparatively. Lab-scale flame tests on PUTs confirmed their self-extinguishing property with little or no smoke evolution. Such PUT resins can be blended with conventional polyurethane coatings for fire-retardant applications.

A family of 2p-3d complexes based on 4,5-dimethyltriazole nitronyl nitroxide radical: synthesis, structure, and magnetic properties

Three 2p-3d complexes were successfully synthesized by using 4,5-dimethyltriazole nitronyl nitroxide radical. All of the complexes with the same formula of [M(hfac)(2)(4,5-di-Me-3-NIT-trz)(2)] [M = Co(II) 1, Ni(II) 2, Cu(II) 3; 4,5-di-Me-3-NIT-trz = 2-[3-(4,5-dimethyl-T2,4-triazolyel-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide; hfac = hexafluomacetylacetone] are characterized by X-ray analysis, and their magnetic properties were studied in detail. The metal ions in 1-3 are all in distorted octahedral configuration with four oxygen atoms from two bidentate hfac ligands, and two triazole N atoms from two different 4,5-di-Me-3-NIT-trz ligands. The magnetic behaviors for 1-3 indicate that the metal ions and the radicals are antiferromagnetically coupled (J(Co-rad) = -7.11 cm(-1), for 1; J(Ni-rad) = -1.63 cm(-1), for 2; J(Cu-rad) = -8.71 cm(-1), for 3). In addition, ferromagnetic coupling exists between the uncoordinated NO radicals in complex 1, while the magnetic reactions J(rad-rad) are antiferromagnetic in complexes 2-3.
