A variety of beta-aryl ketones and aldehydes were facilely synthesized via a Pd(II)/Ag2CO3-mediated decarboxylative Heck type reaction between readily available benzoic acid derivatives and allylic alcohols under mild conditions. The control experiments indicated that this transformation may proceed via a hydrogen migration process.

4265-25-2, Name is 2-Methylbenzofuran, belongs to benzofurans compound, is a common compound. HPLC of Formula: C9H8OIn an article, once mentioned the new application about 4265-25-2.

The influence of the heating rate and of the presence of oxygen on the decomposition pathways and on the decomposition product yields obtained from the thermal degradation of electronic boards containing brominated flame retardants was investigated. TG-FTIR techniques and a fixed bed batch reactor coupled to different analytical techniques were used to simulate different thermal degradation conditions. The qualitative and quantitative yields of decomposition products at different heating rates and in different reaction environments were obtained and compared to those from the decomposition of the unlinked resin and of tetrabromobisphenol A. Bromine was mainly evolved in the gaseous fraction for all the materials and the experimental conditions considered, although significant quantities are present as well in the condensable fraction. An increase of bromine evolved as gaseous hydrogen bromide was evidenced at higher heating rates. In the presence of oxygen, PBDD and PBDF were detected among the decomposition products. The possible precursors and the likely radical reaction pathways leading to the formation of these compounds were identified on the basis of the experimental data. The results obtained confirm that the formation of highly hazardous organobrominated compounds may be expected from the combustion of electronic scrap and of materials containing brominated flame retardants.

The first asymmetric cooperative Lewis base/palladium catalyzed benzylic alkylation of acyclic esters is reported. This reaction proceeds via stereodefined C1-ammonium enolate nucleophiles. Critical to its success was the identification of benzylic phosphate electrophiles, which were uniquely reactive. Alkylated products were obtained with very high levels of enantioselectivity, and this method has been applied toward the synthesis of the thrombin inhibitor DX-9065a.

This review focuses on a new generation of polymers with intrinsic microporosity (PIMs) and their hydrogen storage applications. PIMs are a novel microporous material attracting attention due to their potentially useful functional properties. In this review, the methods of synthesis, suitable characterisation techniques and applications are briefly described. Importantly, the hydrogen capacity of PIMs that have been investigated recently is highlighted and the hydrogen uptake is compared to other microporous materials such as hypercrosslinked polymers (HCPs), metal organic frameworks (MOFs) and activated carbons. This review brings H2storage-applicable PIMs that have been reported in different studies together for the first time, providing a reference for better comparison of H2storage in PIMs.

Electric Literature of 24673-56-1, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.24673-56-1, Name is 3-Methylbenzofuran-2-carboxylic acid, molecular formula is C10H8O3. In a article，once mentioned of 24673-56-1

The development of a palladium-catalyzed decarboxylative coupling reaction of arene carboxylates with olefinic substrates is described. The optimized procedure for decarboxylative palladation employs Pd(O2CCF3)2 as catalyst (0.2 equiv) in the presence of Ag2CO3 (3 equiv) in the solvent 5% DMSO-DMF and proceeds at temperatures of 80-120 C with a wide range of arene carboxylates and alkenes as substrates. The process is proposed to proceed by an initial Ar-SE reaction involving ipso attack of an electrophilic Pd(II) intermediate on an arene carboxylate to form an arylpalladium(II) species with loss of carbon dioxide. This intermediate is then proposed to react with an olefinic substrate by steps common to the Heck coupling process. Reoxidation of the liberated Pd(0) in situ is proposed to establish the catalytic cycle. Copyright

Media formulated using two compounds (a leuco dye and 4-alkoxyl-4?-hydroxybiphenyl) were colored in the amorphous state and colorless in the crystalline state. As the alkyl chain length of the biphenyl compound increased, the contrast ratio and thermal stability of the amorphous states increased. Additionally, the crystallization velocity increased for the media with a long alkyl chain. Leuco dyes with a high glass transition temperature also produced thermally stable amorphous states. The origin of the long alkyl chain effects is discussed.
