And the article was published in Beilstein Journal of Organic Chemistry in 2022. Computed Properties of C6H5BrO2 The author mentioned the following in the article:

A simple elec. mortar-pestle was used for the development of a green and facile mechanochem. route for the catalyst-free halogenation of phenols and anilines via liquid-assisted grinding using PEG-400 as the grinding auxiliary. A series of mono-, di-, and tri-halogenated phenols and anilines was synthesized in good to excellent yields within 10-15 min in a chemoselective manner by controlling the stoichiometry of N-halosuccinimides (NXS, X = Br, I, and Cl). It was observed that PEG-400 plays a key role in controlling the reactivity of the substrates and to afford better regioselectivity. Almost exclusive para-selectivity was observed for the aromatic substrates with free o- and p-positions for mono- and dihalogenations. As known, the decarboxylation (or desulfonation) was observed in the case of salicylic acids and anthranilic acids (or sulfanilic acids) leading to 2,4,6-trihalogenated products when 3 equiv of NXS was used. Simple instrumentation, metal-free approach, cost-effectiveness, atom economy, short reaction time, and mild reaction conditions are a few noticeable merits of this environmentally sustainable mechanochem. protocol. In the part of experimental materials, we found many familiar compounds, such as 2-Bromobenzene-1,4-diol(cas: 583-69-7Computed Properties of C6H5BrO2)

2-Bromobenzene-1,4-diol(cas: 583-69-7) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl.

Application of 583-69-7On October 20, 2021 ,《A Molecular Replication Process Drives Supramolecular Polymerization》 was published in Journal of the American Chemical Society. The article was written by Feng, Yuanning; Philp, Douglas. The article contains the following contents:

Supramol. polymers are materials in which the connections between monomers in the polymer main chain are non-covalent bonds. This area has seen rapid expansion in the last two decades and has been exploited in several applications. However, suitable contiguous hydrogen-bond arrays can be difficult to synthesize, placing some limitations on the deployment of supramol. polymers. We have designed a hydrogen-bonded polymer assembled from a bifunctional monomer composed of two replicating templates separated by a rigid spacer. This design allows the autocatalytic formation of the polymer main chain through the self-templating properties of the replicators and drives the synthesis of the bifunctional monomer from its constituent components in solution The template-directed 1,3-dipolar cycloaddition reaction between nitrone and maleimide proceeds with high diastereoselectivity, affording the bifunctional monomer. The high binding affinity between the self-complementary replicating templates that allows the bifunctional monomer to polymerize in solution is derived from the pos. cooperativity associated with this binding process. The assembly of the polymer in solution has been investigated by diffusion-ordered NMR spectroscopy. Both microcrystalline and thin films of the polymeric material can be prepared readily and have been characterized by powder X-ray diffraction and SEM. These results demonstrate that the approach described here is a valid one for the construction of supramol. polymers and can be extended to systems where the rigid spacer between the replicating templates is replaced by one carrying addnl. function.

Muramatsu, Tatsuya; Okado, Yuji; Traeger, Hanna; Schrettl, Stephen; Tamaoki, Nobuyuki; Weder, Christoph; Sagara, Yoshimitsu published an article in Journal of the American Chemical Society. The title of the article was 《Rotaxane-Based Dual Function Mechanophores Exhibiting Reversible and Irreversible Responses》.Application of 583-69-7 The author mentioned the following in the article:

Mechanochromic mechanophores permit the design of polymers that indicate mech. events through optical signals. Here we report rotaxane-based supramol. mechanophores that display both reversible and irreversible fluorescence changes. These responses are triggered by different forces and are achieved by exploiting the mol. shuttling function and force-induced dethreading of rotaxanes. The new rotaxane mechanophores are composed of a ring featuring a luminophore, which is threaded onto an axle with a matching quencher and two stoppers. In the stress-free state, the luminophore is preferentially located in the proximity of the quencher, and the emission is quenched. The luminophore slides away from the quencher when a force is applied and the fluorescence is switched on. This effect is reversible, unless the force is so high that the luminophore-carrying ring slips past the stopper and dethreading occurs. We show that the combination of judiciously selected ring and stopper moieties is crucial to attain interlocked structures that display such a dual response. PU elastomers that contain such doubly responsive rotaxanes exhibit reversible fluorescence changes over multiple loading-unloading cycles due to the shuttling function, whereas permanent changes are observed upon repeated deformations to high strains due to breakage of the mech. bond upon dethreading of the ring from the axle. This response allows one, at least conceptually, to monitor the actual deformation of polymer materials and examine mech. damage that was inflicted in the past on the basis of an optical signal. In the experiment, the researchers used 2-Bromobenzene-1,4-diol(cas: 583-69-7Application of 583-69-7)

《Dual character of peroxymonosulfate oxidation process to treat salty wastewater containing 2,4,6-tribromophenol》 was written by Fang, Changling; Lou, Xiaoyi; Tang, Yunyu; Tian, Liangliang; Cai, Youqiong; Xiao, Dongxue; Guo, Yaoguang; Liu, Jianshe. Name: 2-Bromobenzene-1,4-diol And the article was included in Journal of Environmental Chemical Engineering on August 31 ,2020. The article conveys some information:

Nowadays, increasing attention has been paid on the peroxymonosulfate (PMS) in situ oxidation for environmental decontamination. Chloride ion (Cl-) could directly react with PMS to produce some reactive halogen agents via non-radical pathways. In present study, the degradation kinetics of 2,4,6-tribromophenol (TBP) and the total organic carbon (TOC) removal by adding PMS in salty wastewater were inspected. TBP could effectively degraded by PMS in salty wastewater over the pH range of 3.0-7.0, and the degradation ratio increased with the pH of reaction solution Pos. effects of Cl- concentration (1-100 mM) on TBP degradation kinetics were also examined Moreover, the oxidation products and their evolution with reaction time were conducted in order to further evaluate the environmental benefits with co-existence of PMS and Cl-. Instead of complete mineralization, TBP was mainly transformed to new halogenated products which also have long half-lives. The chlorination of TBP is the dominant pathway in the presence of Cl-, since the main oxidant (HOCl) played an important role. The formation of undesirable halogenated products provides that adding PMS into salty wastewater might not be an unexpected proposal for TBP depletion involving of the attendance of chloride. The experimental process involved the reaction of 2-Bromobenzene-1,4-diol(cas: 583-69-7Name: 2-Bromobenzene-1,4-diol)

Product Details of 583-69-7On May 31, 2019, Li, Yang-Yang; Liu, Hong; Xu, Ying; Zhou, Ning-Yi published an article in International Biodeterioration & Biodegradation. The article was 《A two-component monooxygenase initiates a novel 2-bromo-4-nitrophenol catabolic pathway in newly isolated Cupriavidus sp. strain NyZ375》. The article mentions the following:

As a vital byproduct of chem. intermediates for pesticides and cytotoxin inhibitors, 2-bromo-4-nitrophenol (2B4NP) is toxic to aquatic life. However, bacterial cultures mineralizing 2B4NP have not been reported. In this study, Cupriavidus sp. strain NyZ375 was isolated from aromatics-polluted soil and identified by 16S rRNA gene sequencing. Via an oxidative pathway, it grows on 120μM 2B4NP as the only carbon source, releasing approx. equivalent amount of nitrite. Three genes (bnpABC) in a 4.8-kb DNA fragment from a draft genome was found to be responsible for the initial reactions in 2B4NP degradation BnpAB are the monooxygenase and flavin reductase components, resp., catalyzing the monooxygenation of 2B4NP to bromohydroquinone (BHQ, 63%) and 1,2,4-benzenetriol (BT, 37%) with concomitant nitrite release, in the presence of NADH and FAD. BnpC is a hydroxyquinol 1,2-dioxygenase catalyzing the ring-cleavage oxidation of BT to maleylacetate. The byproduct BHQ was not further degraded by strain NyZ375 but was not toxic to its growth at a concentration of 100μM. It can be tentatively concluded that BnpAB is evolutionary close to the 2,4,6-trichlorophenol monooxygenase TcpAX from Cupriavidus necator JMP134. The 2B4NP catabolism by this new isolate illustrates a pathway distinct from those of all identified 2-chloro-4-nitrophenol utilizers. In addition to this study using 2-Bromobenzene-1,4-diol, there are many other studies that have used 2-Bromobenzene-1,4-diol(cas: 583-69-7Product Details of 583-69-7) was used in this study.

Song, Ningning; Yao, Hongyan; Ma, Tengning; Wang, Tianjiao; Shi, Kaixiang; Tian, Ye; Zou, Yongcun; Zhu, Shiyang; Zhang, Yunhe; Guan, Shaowei published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《Fabrication of microporous polyimide networks with tunable pore size and high CO2 selectivity》.COA of Formula: C6H5BrO2 The author mentioned the following in the article:

Developing porous organic polymer materials with plenty micropores is of great importance for highly selective CO2 capture under ambient conditions. Here, to tune the pore size, two novel microporous hyperbranched polyimide networks, in which the distance between the polymer skeleton and crosslinking points is different, are successfully prepared by a two-step pathway combining polymerization and crosslinking reaction. It is intriguingly found that both porosity and CO2 sorption performance of microporous hyperbranched polyimides can be finely tuned by reducing the distance between the polymer skeleton and crosslinking points from PEPHQDA-HBPI-CL to PEQDA-HBPI-CL. The micropore size decrease from 1.18 nm to 0.86 nm, and CO2 adsorption capacity increase from 6.38 to 6.51 wt% (298 K and 1 bar). More excitingly, the PEQDA-HBPI-CL demonstrates the high CO2/N2 and CO2/CH4 selectivity up to 109 and 15 (273 K, 1 bar) according to the Henry’s law, which are superior to those of many other microporous organic polymers and among the best results for porous inorganic/ organic materials. This work reveals that the shorter-distance between the polymer skeleton and crosslinking points is in favor of fabricating microporous hyperbranched polyimide networks with abundant smaller micropore and high CO2 selectivity, which are crucial importance for the CO2 capture and storage. In addition to this study using 2-Bromobenzene-1,4-diol, there are many other studies that have used 2-Bromobenzene-1,4-diol(cas: 583-69-7COA of Formula: C6H5BrO2) was used in this study.

We report Suzuki-Miyaura coupling polymerization of tetraalkoxy-substituted 4-bromostilbene-4′-boronic acid 1 with several t-Bu3P-ligated Pd initiators; this is the first example of catalyst-transfer condensation polymerization (CTCP) of a monomer containing a carbon-carbon double bond. When o-tolylPd(tBu3P)Br was used as the initiator, the o-tolyl group was not introduced at the polymer end, but polymer with boronic acid at one end and bromine at the other was obtained. However, when we employed stilbenePd(tBu3P)I generated in situ from iodostilbene and Pd(tBu3P)G2 precatalyst, or isolated ArPd(tBu3P)X (Ar, X = Ph, I; o-tolyl, I; and Ph, Br), the aryl group was introduced at the polymer end, indicating that CTCP of 1 proceeded. Therefore, the iodide and aryl group of the Pd initiator complex is crucial for CTCP of 1. However, the mol. weight distribution of the obtained polymer was broad, possibly because coordination of the carbon-carbon double bond of 1 to ArPd(tBu3P)I resulted in slow initiation. © 2018 Wiley Periodicals, Inc.
