Proton magnetic resonance spectra of some benzo[b]thiophene derivatives was written by Chapman, Norman Bellamy;Ewing, David F.;Scrowston, R. M.;Westwood, R.. And the article was included in Journal of the Chemical Society [Section] C: Organic in 1968.Computed Properties of C11H9BrO2S The following contents are mentioned in the article:

Attempts are made to correlate the chem. shifts in the 100 Mc./sec. 1H N.M.R. spectra of 42 benzo[b]thiophene derivatives with the substituents present in the mol., and the relations are rationalized where possible. Coupling constants are also recorded, and their dependence on bond order and on other factors is discussed. The changes in the chem. shifts and coupling constants when the benzo[b]thiophenes are oxidized to the 1,1-dioxides are recorded and discussed. 43 references. This study involved multiple reactions and reactants, such as Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1Computed Properties of C11H9BrO2S).

Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is also used in the manufacturing of dyes such as thioindigo.Computed Properties of C11H9BrO2S

Pharmacologically active benzo[b]thiophene derivatives. III. 2-Substituted compounds was written by Chapman, Norman Bellamy;Clarke, Kenneth;Saraf, S. D.. And the article was included in Journal of the Chemical Society [Section] C: Organic in 1967.Application of 13771-68-1 The following contents are mentioned in the article:

cf. CA 62, 6450f; 65, 18549g. A number of N-(5-substituted-2-benzo[b]thenyl)ethanolamines (I) and the corresponding N-Me and N-Et derivatives were prepared by condensation of the 5-substituted 2-chloromethylbenzo[b]thiophenes with ethanolamine, N-methylethanolamine, or N-ethylethanolamine. These amino alcs. treated with SOCl2 in dry CHCl3 gave the corresponding β-chloroethylamines (II). 2-Acetyl-5-bromo- and -5-chlorobenzo[b]thiophene were prepared Bromination of these ketones, followed by condensation with several secondary amines, gave oxo amines, which were reduced with NaBH4 in aqueous MeOH to give corresponding amino alcs., some of which reacted with SOCl2 in dry CHCl3 as above. This study involved multiple reactions and reactants, such as Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1Application of 13771-68-1).

Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.Application of 13771-68-1

Benzothiophene-flanked diketopyrrolopyrrole polymers: impact of isomeric frameworks on carrier mobilities was written by Huang, Jianyao;Liu, Xiaotong;Gao, Dong;Wei, Congyuan;Zhang, Weifeng;Yu, Gui. And the article was included in RSC Advances in 2016.Category: benzothiophene The following contents are mentioned in the article:

Exploring new building blocks for solution-processable polymeric semiconductors has attracted much attention. We herein develop two isomeric benzothiophene-flanked diketopyrrolopyrrole polymers with different linkage positions and further systematically study the electronic structures, optical properties, and field-effect characteristics. Both polymers exhibit typical p-type transport characteristics with the highest mobility being up to 0.80 cm² V^-1 s^-1. Our results suggest that the isomeric backbones for conjugated polymers greatly affect charge transport properties. This study involved multiple reactions and reactants, such as Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1Category: benzothiophene).

Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Category: benzothiophene
