The synthesis of aromatic ketones containing benzene ring, naphthalene ring or aromatic heterocycle in the presence of zeolite catalysts has been discussed. The replacement of the classical acid catalysts mainly AlCl3 or HF by a zeolite diminishes the environmental problems. Different acylating agents are used acid chlorides, anhydrides or carboxylic acids. The mechanism of the acylation in the presence of zeolite catalysts is supposed to include acylium cation as electrophilic species. BEA zeolite is most studied.

Rhodococcus sp. strain JVH1 was previously reported to use a number of compounds with aliphatic sulfide bridges as sulfur sources for growth. We have shown that although JVH1 does not use the three-ring thiophenic sulfur compound dibenzothiophene, this strain can use the two-ring compound benzothiophene as its sole sulfur source, resulting in growth of the culture and loss of benzothiophene. Addition of inorganic sulfate to the medium reduced the conversion of benzothiophene, indicating that benzothiophene metabolism is repressed by sulfate and that benzothiophene is therefore used specifically as a sulfur source. JVH1 also used all six isomers of methylbenzothiophene and two dimethylbenzothiophene isomers as sulfur sources for growth. Metabolites identified from benzothiophene and some methylbenzothiophenes were consistent with published pathways for benzothiophene biodesulfurization. Products retaining the sulfur atom were sulfones and sultines, the sultines being formed from phenolic sulfinates under acidic extraction conditions. With 2-methylbenzothiophene, the final desulfurized product was 2-methylbenzofuran, formed by dehydration of 3-(o-hydroxyphenyl) propanone under acidic extraction conditions and indicating an oxygenative desulfination reaction. With 3-methylbenzothiophene, the final desulfurized product was 2-isopropenylphenol, indicating a hydrolytic desulfination reaction. JVH1 is the first microorganism reported to use all six isomers of methylbenzothiophene, as well as some dimethylbenzothiophene isomers, as sole sulfur sources. JVH1 therefore possesses broader sulfur extraction abilities than previously reported, including not only sulfidic compounds but also some thiophenic species.

Reference 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.

The decomposition of 2-isopropylphenol (IPP) was studied in supercritical water at 723-823 K with a water density of 0-0.5 g/cm3 in the absence of catalyst. The main products were phenol, 2-propylphenol (PP), 2-cresol and 2-ethylphenol. The reaction was determined to proceed as follows. At first, the dealkylation and rearrangement of IPP yielded phenol and PP, respectively. Next, the dealkylation of PP lead to the formation of 2-cresol and 2-ethylphenol. The conversion of IPP and the selectivity of phenol increased with the increasing water density, which led to an increase in the yield of phenol. The recoveries of phenol as high as 43% can be obtained in the high water density (0.5 g/cm3) region at 773 K. The rate constant for decomposition of IPP was correlated with a global reaction model for a range of temperatures from 613 to 823 K.

Fast pyrolysis of a lignite containing a high content of oxygen was investigated to understand the effects of pyrolysis temperature and gas resident time on the yields of pyrolysis products and the distributions of organic oxygen species (OOSs). OOSs in the lignite contain carboxyl, carbonyl, hydroxyl and ether by the results of XPS and FTIR analyses. The tar yield reached the maximum of 15.3% at 500 C and a gas resident time of 2.5 s. CO2 was found to be the predominant oxygenous gas at 600 C, and the significant release of CO2 at temperatures lower than 400 C should be related to the high carboxyl content in the lignite. The CO yield increased significantly with the raising temperature and reached 46.4 mL/g (daf) at 700 C. The O yield in water was lower than 20% during pyrolysis at 200 C, and sharply increased to 30.6% at 700 C because of thermal cracking of volatiles. Above 400 C, the OOSs are mainly released as pyrolysis water and gas. The OOSs detected in the tar include phenols, ketones, ethers, alcohols, and dibenzofuran and its substitute, among which phenols (phenol, cresol, and xylenol) are the main components with yield up to 27.1% (based on tar) at 500 C and gas residence time of 10 s. The possible oxygen transformation routes for BYHL pyrolysis are also discussed in this work. Such an approach may lead to the development of efficient lignite upgrading technology.

The aim of this study was to investigate the formation of furan and acrylamide and to compare antioxidant capacities and volatile compounds in cold or hot brewed coffees. Cold brews were prepared at 5 C and 20 C for 12 h. using steeping and dripping, and hot brews were prepared at 80 C and 95 C for 5 min. using the pour-over method. Furan contents of cold steeping at 5 C and hot brewed at 80 C showed the higher levels significantly (p < 0.05), which were 17.0 ± 0.5 and 10.6 ± 0.1 ng/mL, respectively. However, acrylamide contents in cold steeping at 5 C and hot brew at 80 C showed lower levels, which were 4.1 ± 0.4 and 3.5 ± 0.1 ng/mL respectively. Cold brews at 20 C showed the highest levels of antioxidant activities while hot brews showed similar levels with cold brews at 5 C. This study confirms that levels of different beneficial and hazardous chemical compounds could be manipulated by adjusting the coffee extraction conditions.

An abandoned chemical plant in Asturias (Spain) was studied using a multi-faceted molecular fingerprinting approach, demonstrating that it is possible to: (1) carefully unravel tangled evidence resulting from multiple pollution sources, and (2) recognize major contaminants largely ignored by conventional analyses. This methodology employed a battery of GC-MS analyses of liquid chromatographic fractions of soil extracts, plus the pyrolysis products of the soil extract’s asphaltene fraction and the whole soil itself. In this example, coal tar distillation and the subsequent production of naphthalene, phenols and polymer resins are responsible for most of the soil contamination. Styrene, naphthalene, indene and their methylated derivatives and dimers (most notably naphthyl-methylnaphthalene) are particularly abundant and/or distinctive. It is remarkable that most of the contaminants were detected simply by pyrolysis GC-MS, demonstrating its effectiveness for rapid environmental forensic screening of organic contamination. Commonly used environmental analytical approaches would likely have overlooked the predominant pollutants at this site. This could lead to serious shortcomings in remediation planning and implementation. The novel methodology presented herein appears practical and applicable to complex contaminated brownfield sites around the world.

A new approach for the cyclopenta[b]annulation of heteroarenes through metal-free and directing-group-free gamma?[C(sp3)?H] functionalization and intramolecular hydroalkylation of ynones has been developed. In an unprecedented event, nucleophilic addition of an organophosphine to the designed ynones triggers gamma?[C(sp3)?H] functionalization, leading to the formation of heteroaryl-based ortho-quinodimethane (oQDM) intermediates that undergo carbocyclization to provide cyclopentannulated heteroarenes in good yields and excellent stereoselectivities. Deuterium-labeling experiments substantiated the proposed reaction mechanism as well as the speculated epimerization.

The direct alkynylation of benzofurans was achieved for the first time using the hypervalent iodine reagent 1-[(triiso-propylsilyl)ethynyl]-1,2- benziodoxol-3(1H)-one (TIPS-EBX) based on the cooperative effect between a gold catalyst and a zinc Lewis acid. High selectivity was observed for C2-alkynylation of benzofurans substituted with alkyl, aryl, halogen and ether groups. The reaction was also successful in the case of the more complex drug 8-methoxypsoralen (8-MOP).
