Electric Literature of 4265-25-2, 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, 4265-25-2, 2-Methylbenzofuran, introducing its new discovery.

In this work, the pyrolysis of furans (furan, 2-methylfuran, furfuryl alcohol, and furfural) have been checked by Py-GC-MS at 1100 C to detect the decomposition of furans and the formation of benzene derivatives and PAH. From the Py-GC-MS results, different side chain functional groups on furan-ring lead to different kinds of products and product distributions, such as hydroxyl group leading to dimers, and aldehyde group leading to pyrans, but the mechanism for furan-ring opening and decomposition is universal for furans pyrolyzed in this study. In order to explain the experimental results and the formation of benzene derivatives and PAH, the formation of benzene from furan has also been calculated by B3LYP/6-31G + +(d,p). Two possible benzene formation mechanisms, Diels-Alder and acetylene reaction mechanism, have been proposed and calculated. By comparison, it has been regarded that Diels-Alder reaction was more possible for PAH formation as this mechanism has a lower activation energy for initiation step, but acetylene reaction mechanism was more possible for benzene formation as this mechanism has a lower global activation energy.

The pretreatment of the phosphoric acid is a stage of utmost importance leading to an optimal recovery of the uranium present in this acid. To this end, the degradation of the organic matter which obstructs considerably this recovery was tested by gamma irradiation. This study lies within the scope of the radiation/matter interaction; concerning the use of the gamma irradiator as proceed of phosphoric acid purification by the degradation of di butyl phthalate (DBP). Studies of the interaction of gamma radiation with phosphoric acid solutions polluted by an organic matter concern the study of the influence of some parameters such as: dose rate (0.5-35 kGy), initial concentration (50-500 mg/L) of the pollutant, pH and % in P2O5 on the degradation of organic matter by gamma irradiation. The reactions followed pseudo first order kinetics for different initial concentrations. The results made it possible to say that the degradation of di butyl phthalate by gamma irradiation is dependent on the amount of the concentration of DBP and pH. The G-values decreased with absorbed doses, and increased with higher initial concentrations.Purification of phosphoric acid by gamma radiation does not degrade the quality of this acid.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 125-20-2 is helpful to your research. Electric Literature of 125-20-2

Chemistry is traditionally divided into organic and inorganic chemistry. Quality Control of 6-Bromobenzofuran, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 128851-73-0

Herein, we report a facile tandem approach for the synthesis of both spiro-oxindole-fused pyrroloindolines and benzofurano-pyrrolidines via a Lewis acid-catalyzed domino ring-opening with concomitant ring annulation using activated spiro-aziridines and heteroarenes. This method offers a new class of novel spiro-fused polycyclic pyrrolidines in a one-pot and sustainable manner with good yields and high diastereoselectivity. In addition, the structure of 3d was confirmed by single X-ray crystallography analysis.

Histone deacetylases (HDACs) decrease the acetylation level of histones and other non-histone proteins. Over expression of HDACs have been observed in cancers and other diseases. Targeted protein degradation by ?hijacking? the natural ubiquitin-proteasome-system (UPS) recently emerged as a novel technology to ?knock-out? endogenous disease-causing proteins. We applied this strategy to the development of the first small molecule degraders for zinc-dependent HDACs by conjugating non-selective HDAC inhibitors with E3 ubiquitin ligase ligands. Through cell-based assays, we discovered novel bifunctional molecules (dHDAC6) that could selectively degrade HDAC6. Further mechanistic studies indicated that HDAC6 was selectively removed by the UPS.

The polymer-assisted reaction of 4-(hydroxymethyl)furan-2(5H)-one (4HM2F) with 21 carboxylic acids using polystyrene-carbodiimide (PS-carbodiimide) yielded an ester library. Four of the esters, (5-oxo-2,5-dihydrofuran-3-yl) methyl acetate (IS-1), (5-oxo-2,5-dihydrofuran-3-yl)methyl butyrate (IS-2), (5-oxo-2,5-dihydrofuran-3-yl)methyl 2-methylpropanoate (IS-3), and (5-oxo-2,5-dihydrofuran-3-yl)-methyl chloroacetate (IS-4), were tested as internal standards for the quantification of patulin in apple juice by gas chromatography-mass spectrometry in the selected ion monitoring mode (GC-MS-SIM). The developed method combines an AOAC official extractive step and a GC-MS-SIM analysis. Using a chromatographic column containing trifluoropropylmethylpolysiloxane as the stationary phase and IS-1 as the internal standard, it was possible to perform an accurate and precise quantification of underivatizated patulin in apple juice at concentrations down to 6 mug/L. A detection limit of 1 mug/L was established.

A tunable chemoselective trifluoromethanesulfonylation and trifluoromethylation of arenediazonium tetrafluoroborates with Langlois’ reagent (NaSO2CF3) was developed. The Cu2O-catalyzed reaction in DMSO gave aryl trifluoromethanesulfones as the major products. On the other hand, the trifluoromethylated arenes were produced in the presence of oxidant tert-butyl hydroperoxide, CuBF4(MeCN)4, and 2,2?;6?,2 terpyridine (tpy). Both of these transformations proceed under mild conditions and tolerate functional groups.

The present work describes the synthesis of novel Schiff bases (8.1-8.9) in five steps from diethyl oxalate and acetone as starting materials. Condensation of ethyl 1-(2-aminophenyl)-5-methyl-1H-pyrazole-3-carboxylate (6) with aromatic and heteroaromatic aldehydes (7.1-7.9) in presence of sodium sulphate at 50 C in ethanol gave the corresponding imine derivatives (8.1-8.9) in quantitative yields. The structure of these compounds was determined by 1H NMR, mass and IR spectral data. These Schiff’s bases were further evaluated for antibacterial activity against the selected Gram-positive and Gram-negative bacteria pathogens. The antibacterial activity data revealed that Schiff base embedded with heteroaromatic ring was found to exhibit good antibacterial activity than the aromatic ring.
