5394-13-8, Name is 2-Bromobenzo[b]thiophene, belongs to benzothiophene compound, is a common compound. 5394-13-8In an article, authors is Atwater, Bruce, once mentioned the new application about 5394-13-8.

The ability to cross-couple secondary alkyl centers is fraught with a number of problems, including difficult reductive elimination, which often leads to beta-hydride elimination. Whereas catalysts have been reported that provide decent selectivity for the expected (non-rearranged) cross-coupled product with aryl or heteroaryl oxidative-addition partners, none have shown reliable selectivity with five-membered-ring heterocycles. In this report, a new, rationally designed catalyst, Pd-PEPPSI-IHeptCl, is demonstrated to be effective in selective cross-coupling reactions with secondary alkyl reagents across an impressive variety of furans, thiophenes, and benzo-fused derivatives (e.g., indoles, benzofurans), in most instances producing clean products with minimal, if any, migratory insertion for the first time. A wide variety of five-membered-ring heterocycles were successfully cross-coupled to secondary alkyl zinc reagents with the new precatalyst Pd-PEPPSI-IHeptCl, which features a bulky N-heterocyclic carbene ligand. This catalyst suppresses migratory-insertion (rearrangement) pathways, and the desired products are thus formed with high selectivity.

As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 5394-13-8, name is 2-Bromobenzo[b]thiophene. In an article，Which mentioned a new discovery about 5394-13-8, COA of Formula: C8H5BrS.

A palladium-catalyzed asymmetric carbon-carbon cleavage for the preparation of functionalized axially chiral molecules was reported. Increasing ring distortion not only enhanced the reactivity but also improved the chemoselectivity for different carbon-carbon bonds. This protocol enabled the quick synthesis of ketone-containing axially chiral biaryls in high yields and enantioselectivities.Development of new synthetic strategies for enantioselective carbon-carbon and carbon-heteroatom bond formation is one of the pillars of modern organic chemistry. Whereas significant advances have been achieved in center chirality construction, catalytically asymmetric construction of axial chirality is still under development. Moreover, axially chiral molecules constructed through carbon-carbon and carbon-heteroatom bond cleavage are extremely limited. Here, we report an asymmetric synthesis of biaryl atropisomers via palladium-catalyzed chemoselective carbon-carbon cleavage of 9-aryl-9H-fluoren-9-ols. The reaction demonstrated broad substrate scope and produced the atropisomers in high yields and enantioselectivity. The ring-opening reactivity was considerably accelerated by the torsional strain created by the steric repulsion between two ortho-substituents of the biaryl skeleton in the substrates. The high enantiocontrol hinges on the evolvement of a new TADDOL-based phosphoramidite as ligand. These findings set up a new platform for the development of novel synthetic methods via asymmetric carbon-carbon cleavage.Rapid generation of chirality to increase the complexity of molecules is pivotal for organic synthesis, material chemistry, and drug discovery. By taking advantage of ring strain, we developed a palladium-catalyzed asymmetric carbon-carbon bond cleavage reaction for facile access to a series of axially chiral biaryls in an atom-economical fashion. High functional group tolerance, yields, and enantioselectivities were achieved. The method set up a new platform toward axially chiral biaryl units found in many biologically active natural products, drugs, and catalysts. The present work also showcased a promising strategy for the activation of other non-activated molecules via increasing the ring strain by molecular distortion.

Herein we report on the synthesis and acid-responsive emission properties of donor-acceptor (D-A) molecules that contain a thienothiophene unit. 2-Arylthieno[3,2-b]thiophenes were conjugated with an N-methylbenzimidazole unit to form acid-responsive D-A-type fluorophores. The D-A-conjugated fluorophores showed intense intramolecular charge-transfer (ICT) emission in response to acid. The effect of the substitution on their photophysical properties as well as their solvent-dependence indicated non-twisting ICT emission in protonated D-A molecules. The quinoidal character of 2-arylthienothiophene as a donor part is discussed, as it is assumed that it contributes to suppression of the molecular twisting in the excited state, therefore decreasing the nonradiative rate constant, thereby resulting in the intense ICT emission. Acid-base-sensitive triple-color emission was also achieved by the introduction of a base-responsive phenol group in the donor part.

As with benzenoid donors, the electronic absorption spectra of the molecular complexes of simple or condensed sulfur or oxygen-containing five-membered heterocycles with TCNE (or DDQ) often show two charge-transfer bands.In many cases, the knowledge of the actual frequencies requires a technique of resolution.The results so obtained are correlated with the ionization potentials of donors on the one hand, and the refractivity of nonpolar solvents on the other hand.
