A novel and efficient I2/DMSO mediated metal-free strategy is presented for the direct C-C bond cleavage of aryl-/heteroaryl- or aliphatic alpha-ketoaldehydes by C2-decarbonylation and C1-carbonyl oxidation to give the corresponding carboxylic acids followed by esterification in one pot, offering excellent yields in both the steps. Here, DMSO acts as the oxygen source/oxidant and this reaction works very well under both conventional heating and microwave irradiation. This is a very simple and convenient protocol.

A series of different electron-deficient aromatic substituents were used to investigate the role of the electron-acceptor strength on the photophysical properties of salicylaldimine derivatives. These molecules were synthesised and characterised through X-ray diffraction, absorption and emission spectroscopies. Their photochemical reaction mechanisms and properties were explored with the aid of ab initio methods of quantum chemistry. Our results allow us to clarify the dependence of the multiple emission bands on the polarity of the solvent and on the substitution of electron donating and accepting groups to the salicylaldimine core.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C9H8O. Introducing a new discovery about 4265-25-2, Name is 2-Methylbenzofuran

Gas-to-liquids (GTL) and also coal-to-liquids (CTL) Fischer-Tropsch plants using high-temperature (entrained flow) gasification all face the same refining challenge, which is meeting the EN590 density specifications of 820 kg m -3 at 15 C for the produced distillate. Fischer-Tropsch distillates can, however, be blended with high density distillates originating from sources such as crude oil, direct coal liquefaction or coal pyrolysis products, in an effort to conform to those diesel density requirements. Fixed bed dry bottom (FBDB) gasification technology can in combination with high-temperature Fischer-Tropsch (HTFT) synthesis provide a way to produce final on-specification CTL transportation fuels. Hydroprocessing FBDB gasification tar results in a distillate with high density whereas a hydrotreated HTFT distillate corresponds to a highly paraffinic product with high cetane number but low density. Both distillates can be blended to produce a market-ready final diesel which is of particular industrial importance for CTL applications in countries which have no oil but low-rank coals instead and viable options for carbon capture and storage (CCS).

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.COA of Formula: C9H8O, you can also check out more blogs about4265-25-2

A self diastereoselective, simple metal free and efficient branch domino reaction gave multiple heteroaryl substituted (±) cyclohexanols with five chiral centres in >95% yields. The reactions that occur are Claisen Schmidt condensation followed by Michael addition and Aldol reactions of heteroaryl carbaldehydes and acetyl pyridine derivatives. Mechanistic study of the reactions shows excellent self diastereoselectivity (dr > 99%) in the intermediate steps which results selectively in the formation of one set of enantiomers out of sixteen possible enantiomeric pairs. The self diastereoselectivity of reaction in all the steps dominates due to the steric hindrance induced by the bulky heteroaryl groups. The stereochemistry of the synthesized compounds is established using single crystal XRD.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Quality Control of 4,5-Difluorophthalic Anhydride, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 18959-30-3, Name is 4,5-Difluorophthalic Anhydride, molecular formula is C8H2F2O3

A reactive diluent (ODA-PEPA) and a flexible phenylethynyl-terminated imide oligomer (PEI-PEPA) were designed and synthesized based on the 2,3,3?,4?-diphenyl ether tetracarboxylic acid dianhydride (a-ODPA), 3,4?-oxydianiline (3,4?-ODA), and 4-phenylethynylphthalic anhydride (PEPA). Solution blended systems with the addition of 5, 10, and 15 wt% ODA-PEPA to PEI-PEPA oligomer and their cured resin systems were prepared. Results showed that ODA-PEPA is semi-crystalline in nature. The Tg values of cured resins were improved from 273 C to 280 C by the addition of ODA-PEPA, due to the higher crosslink densities. In addition, rheological properties of blends showed lower melt viscosity and wider processing window, revealing improved melt processabilities for potential application in making advanced composites. The isothermal viscosity in 280 C of PEI-PEPA containing 15 wt% ODA-PEPA reactive diluent decreased by two thirds, due to the low molecular weight of ODA-PEPA. The cured blends demonstrated high thermal stability and heat resistance. 5 wt% thermal decomposition temperatures (Td5) of the cured blends were above 549 C and 547 C in N2 and air atmosphere, respectively. The char yield reported at 800 C in N2 atmosphere increased from 58.8% to 63.7 % with the addition of ODAPEPA. Meanwhile, the cured polyimides blends possessed good bond strength (> 9.3 MPa).
