The degradation of two pesticides, carbofuran (CBF) and ioprodine (IPR), was studied by the photolytic decomposition of hydrogen peroxide (UV/H2O2). The influence of two experimental parameters, H2O2 concentration and initial pH, as well as their interactions, was investigated. Optimization was carried out where experimental parameters were determined for the treatment of each pesticide. Both pesticides were totally eliminated by UV/H2O2 system under optimal conditions. However, significant differences were found: CBF degradation was influenced by both parameters and their interactions, while IPR degradation was not statistically affected by initial pH. Interestingly, analysis of degradation pathways showed a major influence of photolysis process and oxidation due to hydrogen peroxide for the CBF degradation, while the synergistic combination between both of them played the most relevant role during IPR degradation. A mixture of both pesticides was also submitted to UV/H2O2 action in which a lower rate was observed for IPR elimination while CBF was not affected. A 90 % of chemical oxygen demand (COD) was removed and 75 % of mineralization was achieved after the treatment of the mixture. Almost 92 % of the toxicity was eliminated making this technique a promising process to treat toxic mixtures of these pesticides.

In a Article，once mentioned of 125-20-2

Roasted and cold-pressed pumpkin seed oil obtained from pumpkin seeds (Cucurbita pepo, L.) from the 2010/2011 to 2012/2013 crop seasons were analyzed to determine the basic quality parameters (free fatty acids and peroxide value) as well as content of cis and trans fatty acids. Free fatty acids and peroxide values were within the legal limits in all except one of the roasted samples and were influenced by climate conditions of a particular crop season, while the significance of influences due to processing conditions was not determined. Gas chromatography revealed a total of 12 cis and 3 trans fatty acids in pumpkin seed oil. The dominant fatty acids in all seed oil samples were linoleic, oleic, palmitic, and stearic (98.8. ±. 0.18%). Their content was significantly affected by the crop season and processing. Higher amounts of saturated and monounsaturated fatty acids were noted in oil from a crop season with higher air temperature and in cold-pressed oil. All pumpkin seed oil contained palmitoleic fatty acid (0.10-0.14%) which is listed as “not detected” in the authenticity requirements for pumpkin seed oil in regulations of various EU countries. The content of trans fatty acids was significantly higher in roasted seed oil (0.03%-0.39%) than in cold-pressed oil (0.03%-0.05%).

Reference of 189035-22-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 189035-22-1, 6-Bromo-2,3-dihydrobenzofuran, introducing its new discovery.

A protocol for the Pd-catalysed cyanation of aryl bromides using near stoichiometric and gaseous hydrogen cyanide is reported for the first time. A two-chamber reactor was adopted for the safe liberation of ex situ generated HCN in a closed environment, which proved highly efficient in the Ni-catalysed hydrocyanation as the test reaction. Subsequently, this setup was exploited for converting a range of aryl and heteroaryl bromides (28 examples) directly into the corresponding benzonitriles in high yields, without the need for cyanide salts. Cyanation was achieved employing the Pd(0) precatalyst, P(tBu)3-Pd-G3 and a weak base, potassium acetate, in a dioxane-water solvent mixture. The methodology was also suitable for the synthesis of 13C-labelled benzonitriles with ex situ generated 13C-hydrogen cyanide. Stoichiometric studies with the metal complexes were undertaken to delineate the mechanism for this catalytic transformation. Treatment of Pd(P(tBu)3)2 with H13CN in THF provided two Pd-hydride complexes, (P(tBu)3)2Pd(H)(13CN), and [(P(tBu)3)Pd(H)]2Pd(13CN)4, both of which were isolated and characterised by NMR spectroscopy and X-ray crystal structure analysis. When the same reaction was performed in a THF : water mixture in the presence of KOAc, only (P(tBu)3)2Pd(H)(13CN) was formed. Subjection of this cyano hydride metal complex with the oxidative addition complex (P(tBu)3)Pd(Ph)(Br) in a 1 : 1 ratio in THF led to a transmetallation step with the formation of (P(tBu)3)2Pd(H)(Br) and 13C-benzonitrile from a reductive elimination step. These experiments suggest the possibility of a catalytic cycle involving initially the formation of two Pd(ii)-species from the oxidative addition of LnPd(0) into HCN and an aryl bromide followed by a transmetallation step to LnPd(Ar)(CN) and LnPd(H)(Br), which both reductively eliminate, the latter in the presence of KOAc, to generate the benzonitrile and LnPd(0).

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. category: benzofuran. Introducing a new discovery about 4265-16-1, Name is Benzo[b]furan-2-carboxaldehyde

A rhodium-catalyzed asymmetric synthesis of 5,5-disubstituted cyclohexa-1,3-dienes has been achieved by [2+2+2] cycloaddition reactions between diynes and Morita-Baylis-Hillman (M-B-H) adducts as unsaturated substrates. Products containing two adjacent chiral centres (quaternary and tertiary, respectively) were obtained with complete diastereoselectivity and high enantioselectivity (84-97%) through a kinetic resolution of the M-B-H adduct. Furthermore, these highly substituted cyclohexadienes reacted with dienophiles to afford the corresponding Diels-Alder cycloadducts in good yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzofuran, you can also check out more blogs about4265-16-1

A considerable number of research papers describing the synthesis and testing of the delta opioid receptor (DOR) ligands, SNC-80 and TAN-67, and analogues of these two compounds, have been published in recent years. However, there have been few reports of the discovery of completely new structural classes of selective DOR ligand. By optimising a hit compound identified by high throughput screening, a new series of tetrahydroisoquinoline sulphonamide-based delta opioid ligands was discovered. The main challenge in this series was to simultaneously improve both affinity and physicochemical properties, notably aqueous solubility. The most active ligand had an affinity (IC50) of 6 nM for the cloned human DOR, representing a 15-fold improvement relative to the original hit 1 (IC50 98 nM). Compounds from this new series show good selectivity for the DOR over mu and kappa opioid receptors. However the most active and selective compounds had poor aqueous solubility. Improved aqueous solubility was obtained by replacing the phthalimide group in 1 by basic groups, allowing the synthesis of salt forms. A series of compounds with improved affinity and solubility relative to 1 was identified and these compounds showed activity in an in vivo model of antinociception, the formalin paw test. In the case of compound 19, this analgesic activity was shown to be mediated primarily via a DOR mechanism. The most active compound in vivo, 46, showed superior potency in this test compared to the reference DOR ligand, TAN-67 and similar potency to morphine (68% and 58% inhibition in Phases 1 and 2, respectively, at a dose of 10 mmol/kg i.v.).

A novel method for the catalytic asymmetric dearomatization by visible-light-activated [2+2] photocycloaddition with benzofurans and one example of a benzothiophene is reported, thereby providing chiral tricyclic structures with up to four stereocenters including quaternary stereocenters. The benzofurans and the benzothiophene are functionalized at the 2-position with a chelating N-acylpyrazole moiety which permits the coordination of a visible-light-activatable chiral-at-rhodium Lewis acid catalyst. Computational molecular modeling revealed the origin of the unusual regioselectivity and identified the heteroatom in the heterocycle to be key for the regiocontrol.
