A short, simple and inexpensive synthesis of several diversely substituted benzo[b]thiophenes and one naphthothiophene is described. The method involves introduction of methylsulfanyl group ortho- to the amide function of readily available N,N-diethylamides of aryl carboxylic acid by directed metalation. Thioindoxyls, obtained in high yields through side-chain deprotonation and cyclisation in one pot, are reduced to benzo[b]thiophene or napthothiophene.

Fifty-seven for the ortho-benzylic coupling constant 4JMe-C=C-H (henceforth denoted as 4JOB) were obtained for a variety of heteroaromatic systems.It was shown that a good correlation exists between 4JOB when the methyl group is not alpha to the heteroatom and the SCF-MO bond order.This method can therefore be used as experimental means of determining bond orders in heteroaromatic systems.An examination of bond alternation in thirteen heteroaromatic systems has given a measure of relative “degree of aromaticity” for a larger number of systems than previously r eported by any single method.

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 16587-47-6 is helpful to your research. name: 6-Methylbenzo[b]thiophene

The abilities of three Pseudomonas strains to transform each of the six isomers of methylbenzothiophene was studied. These compounds would not support growth but were biotransformed in a cell suspension of one of the isolates and in cultures of the other two isolates while they grew on 1- methylnaphthalene or glucose. Sulfur-containing metabolites were identified by GC/MS and GC/FTIR, and when possible, by comparison with authentic standards. Sulfoxides and sulfones were frequently detected and were the most abundant products from 2- and 3-methylbenzothiophene. Two of the isolates oxidized the methyl groups to carboxylic acids which were abundant products from 3-, 5-, and 6-methylbenzothiophenes. Benzothiophenemethanols were often detected, but in very low amounts. 2,3-Diones were observed as metabolites of benzothiophene and those methylbenzothiophenes with a methyl group on the benzene ring. Isomers of tolyl methyl sulfoxide were observed as ring cleavage products from 6- and 7-methylbenzothiophene.

Recommanded Product: 6-Methylbenzo[b]thiophene, New research progress on 16587-47-6 in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. In a article, 16587-47-6, molcular formula is C9H8S, introducing its new discovery.

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.

Methods for the preparation of benzothiophene (3) and its derivatives by cyclization of phenylthioacetals (1) over ZnCl2-promoted montmorillonite clay are described. Reactions in solution resulted in only moderate (ca. 50%) yields of 3 and the formation of diphenyl disulfide (4) and uncharacterized products. The production of 4 was explained by coordination of 1 via its oxygen atom to active sites of the catalyst and subsequent bimolecular processes. Good to excellent yields (67-98%) of 3 and its derivatives were obtained using vapor phase techniques at 200-300C to promote the desired intramolecular cyclizations.

Twenty one (two unidentified) and 14 impurities were detected and identified in the bottom parts of the zone refined ingots of commercially available ex-coal tar acenaphthene and pyrene, respectively, with the help of Hewlett-Packard gas chromatographs type 6890 GC System and 5890 series II equipped with fused silica capillary columns and the FID and MS detectors. The result of quantitative determination have shown that naphthalene, 2-methylnaphthalene and 9H-fluorene, and 7-methylanthracene, 1-phenylnaphthalene, fluoranthene and unknown compound with the molecular weight of 208 may be treated as the major impurities of the above hydrocarbons, respectively. These results have also shown that with the exception of methyldibenzofuran present as impurity in acenaphthene, the segregation coefficients of all the remaining detected impurities are lower than unity. Moreover, it was found that the final distribution of the major impurities after 100 passes of the melting zone may be described with high accuracy by a third-order equation. The purification procedure worked out on the basis of the determined impurity segregation behaviour enabled the preparation of the hydrocarbons with purity ?99.999mass% from which high quality crystals were grown.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst, therefore, does not appear in the reaction it catalyzes. In my other articles, you can also check out more blogs about 16587-47-6. Related Products of 16587-47-6
