A novel route was reported for C-H hydroxylation of benzyl compounds directed by a 3,4,5-tribromopyrazole auxiliary via boronation/oxidation using BBr3 and NaBO3·4H2O. The strategy exhibited outstanding site selectivity and afforded the corresponding phenols in moderate to excellent yields under metal-free conditions. Besides, this protocol was achieved in one pot, which is highly promising as a practical method for use in a multistep organic synthetic process.

And the article contained the following:

The visible-light photoredox-catalyzed carboxylation of benzyl chlorides and bromides with CO2 has been reported. With inexpensive organic dyes as photocatalysts and amines as electron donors, this carboxylation proceeds well in the absence of sensitive organometallic reagents, transition metal catalysts, or metallic reductants. A wide range of com. available and inexpensive benzyl halides undergo such carboxylation to give valuable aryl acetic acids, including several pharmaceutical mols. and drug precursors, in moderate to high yields. Moreover, this reaction features mild reaction conditions (one atm. pressure of CO2 and room temperature), broad substrate scope, good functional group tolerance, easy scalability, and low catalyst loading, thus providing an efficient approach for the assembly of aryl acetic acids. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Application In Synthesis of 4-(Bromomethyl)-1,1′-biphenyl

And the article contained the following:

5-Substituted and 5,6-disubstituted [4]acenes were synthesized by the double cationic cyclization of fluoroalkenes. (a) After being treated with Me2AlCl (1.2 equiv), 2-trifluoromethyl-1-alkenes bearing two aryl groups underwent domino Friedel-Crafts-type cyclization (two-ring construction) followed by dehydrogenation to generate 5-fluorinated [4]acenes. The same (trifluoromethyl)alkenes were treated with both Me2AlCl (1.2 equiv) and Me3Al (1.0 equiv), resulting in selective one-ring construction and the creation of bicyclic 1,1-difluoro-1-alkenes. (b) When treated with triflic acid, the bicyclic difluoroalkenes underwent regioselective protonation to generate CF2 cations; Friedel-Crafts-type cyclization of these cations provided tetracyclic ketones. The obtained ketones act as an appropriate platform for the introduction of substituents at the 5-position of [4]acenes. (c) When treated with DDQ/H+, the bicyclic difluoroalkenes underwent oxidative generation of allylic CF2 cations; Friedel-Crafts-type cyclization of these cations produced tetracyclic enones. The enones were subjected to double addition of carbanions to facilitate the introduction of two substituents at the 5- and 6-positions of dihydro[4]acenes.

On July 26, 2021, Ravula, Thirupathi; Ramamoorthy, Ayyalusamy published an article.Application In Synthesis of 4-(Bromomethyl)-1,1′-biphenyl The title of the article was Synthesis, Characterization, and Nanodisc Formation of Non-ionic Polymers. And the article contained the following:

Although lipid nanodiscs are increasingly used in the structural studies of membrane proteins, drug delivery and other applications, the interaction between the nanodisc belt and the protein to be reconstituted is a major limitation. To overcome this limitation and to further broaden the scope of nanodiscs, a family of non-ionic amphiphilic polymers synthesized by hydrophobic functionalization of fructo-oligosaccharides/inulin is reported. We show the stability of lipid nanodiscs formed by these polymers against pH and divalent metal ions, and their magnetic-alignment properties. The reported results also demonstrate that the non-ionic polymers extract membrane proteins with unprecedented efficiency. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Application In Synthesis of 4-(Bromomethyl)-1,1′-biphenyl

On March 15, 2022, Grant, Thomas M.; Rennison, David; Cervin, Gunnar; Pavia, Henrik; Hellio, Claire; Foulon, Valentin; Brimble, Margaret A.; Cahill, Patrick; Svenson, Johan published an article.Quality Control of 4-(Bromomethyl)-1,1′-biphenyl The title of the article was Towards eco-friendly marine antifouling biocides – Nature inspired tetrasubstituted 2,5-diketopiperazines. And the article contained the following:

Marine biofouling plagues all maritime industries at vast economic and environmental cost. Previous and most current methods to control biofouling have employed highly persistent toxins and heavy metals, including tin, copper, and zinc. These toxic methods are resulting in unacceptable environmental harm and are coming under immense regulatory pressure. Eco-friendly alternatives are urgently required to effectively mitigate the neg. consequence of biofouling without causing collateral harm. Amphiphilic micropeptides have recently been shown to exhibit excellent broad-spectrum antifouling activity, with a non-toxic mode of action and innate biodegradability. The present work focused on incorporating the pharmacophore derived from amphiphilic micropeptides into a 2,5-diketopiperazine (DKP) scaffold. This privileged structure is present in a vast number of natural products, including marine natural product antifoulants, and provides advantages of synthetic accessibility and adaptability. A novel route to sym. tetrasubstituted DKPs was developed and a library of amphiphilic 2,5-DKPs were subsequently synthesized. These biodegradable compounds were demonstrated to be potent marine antifoulants displaying broad-spectrum activity in the low micromolar range against a range of common marine fouling organisms. The outcome of planned coating and field trials will dictate the future development of the lead compounds The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Quality Control of 4-(Bromomethyl)-1,1′-biphenyl

Yang, Wu; Li, Yingzi; Zhu, Jiefeng; Liu, Wentan; Ke, Jie; He, Chuan published an article in 2020, the title of the article was Lewis acid-assisted Ir(III) reductive elimination enables construction of seven-membered-ring sulfoxides.COA of Formula: C13H11Br And the article contains the following content:

Iridium has played an important role in the evolution of C-H activation chem. over the last half century owing to its high reactivity towards stoichiometric C-H bond cleavage; however, the use of Ir(III) complexes in catalytic C-H functionalization/C-C bond formation appears to have fallen off significantly. The main problem lies in the reductive elimination step, as iridium has a tendency to form stable and catalytically inactive Ir(III) species. Herein, with a rationally designed Lewis acid assisted oxidatively induced strategy, the sluggish Ir(III) reductive elimination is successfully facilitated, enabling the facile C-C bond formation. The X-ray crystal structure of a silver salt adduct of iridacycle and DFT calculations demonstrate that the sulfoxide group acts as a key bridge connecting the Ir(III) metal center with the silver Lewis acid, which facilitates the reductive elimination of the Ir(III) metallacycle. Further identification of oxidants was carried out by performing stoichiometric reactions, which enables the development of catalytic construction of various highly functionalized seven-membered-ring sulfoxides e.g., 5,7-dihydrodibenzo[c,e]thiepine 6-oxide, that are of great interest in medicinal chem. and materials science. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).COA of Formula: C13H11Br

Shu, Chenglin; Liu, Caiping; Wu, Mingyan; Chen, Cheng; Hong, Maochun published an article in 2021, the title of the article was Simultaneous fluorescence and phosphorescence in Zn(II)-zwitterionic coordination polymers with tunable colors.SDS of cas: 2567-29-5 And the article contains the following content:

Three similar ionic-type ligands which can provide ligand-centered charge transfer (LCCT) have been employed to synthesize three isostructural complexes, resp. Due to the coordination of the ligands to the metal centers, all of the above mentioned complexes feature fluorescence and phosphorescence properties simultaneously. The mechanism of the luminous process is ligand-centered charge transfer (LCCT) combined with metal-to-ligand charge transfer (MLCT) processes. More interestingly, one compound manifests tunable colors from yellow to blue emissions involving white emission by varying the temperature and/or excitation wavelength directly. Exptl. and computational results indicate that the differences in luminous properties originate from the ligand distortion combined with different electron states. Thus, this study provides a facile method to synthesize new single-component tunable-color luminescent coordination polymers with simultaneous fluorescence and phosphorescence.
