The article was titled 《Catalytic Regioselective Cage B(8)-H Arylation of o-Carboranes via “”Cage-Walking”” Strategy》. The information in the text is summarized as follows:

A proof-of-concept example of catalytic regioselective cage B(8)-H functionalization of o-carboranes was disclosed for the 1st time. Under the help of an acylamino directing group at cage B(3), B(8)-arylated, B(4,7,8)-triarylated and B(4,7,8)-trifluorinated o-carborane derivatives were conveniently prepared From isolation of a key intermediate, D labeling experiments and DFT calculations, a reaction mechanism involving a high-valent Pd induced cage-walking from B(4) to B(8) vertex is proposed to account for the regioselective B(8)-H activation. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-iodobenzene(cas: 589-87-7HPLC of Formula: 589-87-7)

1-Bromo-4-iodobenzene(cas: 589-87-7) has been employed as reagent for in situ desilylation and coupling of silylated alkynes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids), as substrate in copper-free Sonogashira coupling in aqueous acetone in synthesis of β,β,dibromostyrenesHPLC of Formula: 589-87-7

《Aminoalkyl radicals as halogen-atom transfer agents for activation of alkyl and aryl halides》 was published in Science (Washington, DC, United States) in 2020. These research results belong to Constantin, Timothee; Zanini, Margherita; Regni, Alessio; Sheikh, Nadeem S.; Julia, Fabio; Leonori, Daniele. SDS of cas: 589-87-7 The article mentions the following:

Organic halides are important building blocks in synthesis, but their use in (photo)redox chem. is limited by their low reduction potentials. Halogen-atom transfer remains the most reliable approach to exploit these substrates in radical processes despite its requirement for hazardous reagents and initiators such as tributyltin hydride. In this study, we demonstrate that α-aminoalkyl radicals, easily accessible from simple amines, promote the homolytic activation of carbon-halogen bonds with a reactivity profile mirroring that of classical tin radicals. This strategy conveniently engages alkyl and aryl halides in a wide range of redox transformations to construct sp3-sp3, sp3-sp2, and sp2-sp2 carbon-carbon bonds under mild conditions with high chemoselectivity. The experimental part of the paper was very detailed, including the reaction process of 1-Bromo-4-iodobenzene(cas: 589-87-7SDS of cas: 589-87-7)

《A Macrocycle Based on a Heptagon-Containing Hexa-peri-hexabenzocoronene》 was written by Jimenez, Vicente G.; David, Arthur H. G.; Cuerva, Juan M.; Blanco, Victor; Campana, Araceli G.. Category: iodides-buliding-blocks And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

A cyclophane is reported incorporating two units of a heptagon-containing extended polycyclic aromatic hydrocarbon (PAH) analog of the hexa-peri-hexabenzocoronene (HBC) moiety (hept-HBC). This cyclophane represents a new class of macrocyclic structures that incorporate for the first time seven-membered rings within extended PAH frameworks. The saddle curvature of the hept-HBC macrocycle units induced by the presence of the nonhexagonal ring along with the flexible alkyl linkers generate a cavity with shape complementarity and appropriate size to enable π interactions with fullerenes. Therefore, the cyclophane forms host-guest complexes with C60 and C70 with estimated binding constants of Ka=420±2 M-1 and Ka=(6.49±0.23)x103 M-1, resp. As a result, the macrocycle can selectively bind C70 in the presence of an excess of a mixture of C60 and C70.1-Bromo-4-iodobenzene(cas: 589-87-7Category: iodides-buliding-blocks) was used in this study.

Application of 589-87-7In 2020 ,《Transition metal-free coupling reactions of benzylic trimethylammonium salts with di(hetero)aryl disulfides and diselenides》 was published in Chemical Communications (Cambridge, United Kingdom). The article was written by Li, Fuhai; Wang, Dan; Chen, Hongyi; He, Ze; Zhou, Lihong; Zeng, Qingle. The article contains the following contents:

A new protocol was developed to synthesize (enantioenriched) thioethers ArCH2SAr1 [Ar = 2-thienyl, Ph, 4-FC6H4, etc.; Ar1 = Ph, 2-pyridyl, 4-O2NC6H4, etc.; stereo = rac, R, S] and selenoethers Ar2CH2SeAr3 [Ar2 = 2-pyridyl, 4-F3CC6H4, 1-naphthyl, etc.; Ar3 = 2-thienyl, Ph, 4-NCC6H4, etc.; stereo = rac, R, S] from (chiral) benzylic trimethylammonium salts and di(hetero)aryl disulfides or diselenides. These synthesis were promoted by presence of weak base and did not require the use of any transition metal, and resulted in target products with good to excellent yields (72-94%). Using quaternary ammonium salts synthesized from enantiomerically enriched amines led to highly enantiopure benzylic thioethers and selenoethers (94-99% ee) with configurations reversed from those of their enantioenriched quaternary ammonium salts.

《Two-Photon Absorption Enhancement by the Inclusion of a Tropone Ring in Distorted Nanographene Ribbons》 was written by Castro-Fernandez, Silvia; Cruz, Carlos M.; Mariz, Ines F. A.; Marquez, Irene R.; Jimenez, Vicente G.; Palomino-Ruiz, Lucia; Cuerva, Juan M.; Macoas, Ermelinda; Campana, Araceli G.. Category: iodides-buliding-blocksThis research focused ontwo photon absorption tropone ring distorted nanographene ribbon; carbon materials; graphene; helicenes; nanostructures; nonlinear optics. The article conveys some information:

A new family of distorted ribbon-shaped nanographenes was designed, synthesized, and their optical and electrochem. properties were evaluated, pointing out an unprecedented correlation between their structural characteristics and the two-photon absorption (TPA) responses and electrochem. band gaps. Three nanographene ribbons have been prepared: a seven-membered-ring-containing nanographene presenting a tropone moiety at the edge, its full-carbon analog, and a purely hexagonal one. We have found that the TPA cross-sections and the electrochem. band gaps of the seven-membered-ring-containing compounds are higher and lower, resp., than those of the fully hexagonal polycyclic aromatic hydrocarbon (PAH). Interestingly, the inclusion of addnl. curvature has a pos. effect in terms of non-linear optical properties of those ribbons.
