Under metal catalyst-free and exogenous-oxidant-free conditions, a series of C-3 aminated imidazo[1,2-a]pyridines were synthesized by electrochemical intermolecular oxidative C-H/N-H cross-coupling. Furthermore, by using a catalytic amount of ferrocene as the mediator, electrochemical intramolecular oxidative C-H/N-H cross-coupling for the synthesis of 10H-benzo[4,5] imidazo[1,2-a]indole derivatives has also been accomplished.

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.

Herein a series of novel bis(pyrazol-1-ylmethyl)pyridine-ligated Cu(i) complexes, C1-C4, bearing different donating groups [[H(C1), Me(C2), t-Bu(C3), Ph(C4)])] on the pyrazole rings, were synthesized and investigated as pre-catalysts in chemical and electrocatalytic water oxidation reactions. Ligands, 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine (L1), 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine (L2), 2,6-bis((3,5-di-tert-butyl-1H-pyrazol-1-yl)methyl)pyridine (L3), and 2,6-bis((3,5-diphenyl-1H-pyrazol-1-yl)methyl)pyridine (L4) were reacted with Cu(MeCN)(4)PF6 to form complexes C1-C4 respectively. Cerium ammonium nitrate (CAN), sodium m-periodate, and sodium persulfate were investigated as chemical oxidants in chemical water oxidation. Complexes C1-C4 showed catalytic activity towards chemical water oxidation in the presence of CAN as the primary oxidant at 25 degrees C. Complex C2 was the most active with a turnover number (TON) of 4.6 and a turnover frequency (TOF) of 0.31 s(-1). The least active catalyst was complex C4, with a TON of 2.3 and a TOF of 0.0086 s(-1). This observed difference in catalytic activity between the complexes illustrated the key role that electronic effects play during catalysis. Other oxidants evaluated with C2 were sodium m-periodate (TON, 3.77; TOF 0.14 s(-1)) and sodium persulfate (TON, 4.02; TOF 0.044 s(-1)) however, CAN exhibited the greatest activity. Complexes C1-C4 were investigated in electrocatalytic water oxidation at a neutral pH of 6.5. Complex C2 was the most active in electrocatalytic water oxidation as well, exhibiting an overpotential of 674 mV and TOF of 9.77 s(-1) (at 1.7 V vs. NHE), which is better than most reported copper(ii) complexes. These Cu(i) complexes C1-C4 show potential as efficient chemical and electrocatalytic water oxidation catalysts, which can be achieved by fine-tuning the steric and electronic properties of the catalysts.

New cis-(1,2-azole)-aquo bis(2,2′-bipyridyl)-ruthenium(II) (1,2-azole (az*H) = pzH (pyrazole), dmpzH (3,5-dimethylpyrazole), and indzH (indazole)) complexes are synthesized via chlorido abstraction from cis-[Ru(bipy)(2)Cl(az*H)]OTf. The latter are obtained from cis-[Ru(bipy)(2)Cl-2] after the subsequent coordination of the 1,2-azole. All the compounds are characterized by H-1, C-13, N-15 NMR spectroscopy as well as IR spectroscopy. Two chlorido complexes (pzH and indzH) and two aquo complexes (indzH and dmpzH) are also characterized by X-ray diffraction. Photophysical and electrochemical studies were carried out on all the complexes. The photophysical data support the phosphorescence of the complexes. The electrochemical behavior of all the complexes in an Ar atmosphere indicate that the oxidation processes assigned to Ru(II) -> Ru(III) occurs at higher potentials in the aquo complexes. The reduction processes under Ar lead to several waves, indicating that the complexes undergo successive electron-transfer reductions that are centered in the bipy ligands. The first electron reduction is reversible. The electrochemical behavior in CO2 media is consistent with CO2 electrocatalyzed reduction, where the values of the catalytic activity [i(cat)(CO2)/i(p)(Ar)] ranged from 2.9 to 10.8. Controlled potential electrolysis of the chlorido and aquo complexes affords CO and formic acid, with the latter as the major product after 2 h. Photocatalytic experiments in MeCN with [Ru(bipy)(3)]Cl-2 as the photosensitizer and TEOA as the electron donor, which were irradiated with >300 nm light for 24 h, led to CO and HCOOH as the main reduction products, achieving a combined turnover number (TONCO+HCOO-) as high as 107 for 2c after 24 h of irradiation.

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.

Bisphenol A (BPA) is a potential endocrine disruptor. It causes hormonal imbalances and also affects aquatic organisms when discharged in untreated form into the ecosystems. Many attempts have been made to degrade BPA in the liquid phase using chemical and or biological methods, which often require multiple steps and are not effective to any great extent. In this study, solution plasma process (SPP) was adopted for the degradation of BPA in liquid phase. BPA at a constant concentration (100 mg. mL(-1)) was degraded using SPP at various of discharge times (0-45 min) and various pH (3-6). Physical conditions for SPP were voltage at 800 V, frequency 35 kHz with bandwidth of 2 mu S and unipolar and bipolar power supplies were used. The degraded BPA was extracted and investigated for the degradation adopting Gas chromatography-Mass Spectroscopy (GC-MS). During SPP, intermediates were formed at 15 min of treatment, and degradation was achieved to a maximum of 86% at 18 min. The GC-MS results revealed that dimethyl ester (91%), hydroxyl-bicyclooctenone (56%), imidazole (23%), pyridine (10%) and benzene (9%) fragments were formed abundantly due to plasma treatment. Plasma-treated BPA was not toxic to aquatic fern, Lemna minor as revealed in relative growth rate (RGR(area)) analysis. SPP causes release of free radicals, which are actively involved in BPA degradation without any additive chemicals. The approach in this study could be projected as an effective SPP-based clean-technology for degradation of toxicants in the aquatic ecosystems and also for effective wastewater treatment.

Computed Properties of C5H8N2. I found the field of Chemistry very interesting. Saw the article A sensitive method for the determination of ultra trace levels of reactive bromine species in water using LC-MS/MS published in 2019.0, Reprint Addresses Lin, KD (corresponding author), Xiamen Univ, Coll Environm & Ecol, Xiamen 361102, Peoples R China.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

The purpose of this study was to develop and validate a sensitive method for the determination of ultra trace levels of reactive bromine species (RBS) in water. To derivatized RBS, water samples were transferred into vials pre-fortified with an appropriate dose of derivative reagent 3,5-dimethyl-1H-pyrazole (DMPZ). RBS in water samples could be rapidly and stoichiometrically (1:1) derivatized to 4-bromo-3,5-dimethyl-1H-pyrazole, which was directly analyzed on an ultra performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry. Parameters influencing the derivatization efficiency including reaction time, temperature, DMPZ dose, and pH were optimized to be: a molar concentration ratio of DMPZ to RBS a 100:1, pH 5-10, and reaction for 10 min at room temperature. In addition, near 100% of RBS was recovered when using water with salinity of 0-55 as the spiking matrices, suggesting that salinity had negligible effect on the derivatization efficiency. Under the optimized conditions, interday and intraday analyses showed that the recoveries of RBS ranged from 88.0% to 109.8% for samples spiked with 18.0-540 pmol L-1 of RBS, with relative standard deviations less than 3.7%. The method limit of detection and limit of quantification for RBS were 5.8 pmol L-1 and 18.0 pmol L-1, respectively. Compared with currently available methods, our method greatly improved the analytical sensitivity by lowering the limit of detection for more than 100 times. The developed method displayed high reliability and reproducibility in the analysis of ultra trace levels of RBS in seawater and other real fresh water samples.

I found the field of Agriculture very interesting. Saw the article Simultaneous measurement of net nitrogen mineralization and denitrification rates in soil using nitrification inhibitor 3,5-dimethylpyrazole published in 2020.0. Recommanded Product: 3,5-Dimethyl-1H-pyrazole, Reprint Addresses Burton, DL (corresponding author), Dalhousie Univ, Dept Plant Food & Environm Sci, Truro, NS B2N 5E3, Canada.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole

A practical means to quantify the response of the rates of net N mineralization and denitrification over a wide range of soil water contents is generally lacking. This study examined the potential to use a nitrification inhibitor (NI) assay system to simultaneously estimate the rates of net N mineralization and denitrification, and applied the NI assay to assess the effect of water content on net N mineralization and denitrification rates in two soils with contrasting soil texture. The compound 3,5-dimethylpyrazole (DMP) applied at a rate of 200 mg kg(-1) was found to provide essentially complete inhibition of nitrification over the duration of the soil incubation for two soils with contrasting soil texture (clay loam vs. sandy loam) and over a range of soil water contents (35%, 55%, and 85% water-filled pore space). This allowed net N mineralization to be estimated as the accumulation of soil ammonium (NHthorn 4) and of denitrification as the disappearance of added nitrate (NO3-). Addition of DMP resulted in a small increase in soil respiration rate but did not appear to influence the rate of net soil N mineralization. The NI assay provides a practical means to quantify the rates of net N mineralization and denitrification simultaneously over a wide range of soil water contents. The assay can be readily scaled up to routinely test multiple soils in an efficient manner, has limited material costs, and is also relatively simple to perform.

Four new derivatives of the versatile polyfunctional ligands 3-(pyrazol-1-yl)propanamide (1, = PPA) and 3-(3,5-dimethylpyrazol-1-yl)-propanamide (2, = Me(2)PPA) have been prepared, in which one of the amide hydrogens on 1 and 2 is formally replaced by alkyl residues. X-Ray diffraction studies revealed that, in contrast to 1 and 2, the N-isopropyl substituted derivatives 3 and 4 form supramolecular hydrogen-bonded chains rather than two-dimensional arrays, and the N-(2-methyl-4-oxypentan-2-yl) (=MOP) substituted compounds 5 and 6 exist as cyclic dimers in the solid state. Reactions of PdCl2(COD) (COD = 1,5-cyclooctadiene) with 2 equiv. of the corresponding ligands 1-6 in all cases afforded trans-PdCl2(L)(2) complexes (7-12). X-ray crystal structure determinations of 8, and 10-12 revealed kappa N-monodentate coordination of the PPA-type ligands. (C) 2019 Elsevier Ltd. All rights reserved.
