Holger. Category: bromides-buliding-blocks. The article was titled 《Self-Assembly of Board-Shaped Diketopyrrolopyrrole and Isoindigo Mesogens into Columnar π-π Stacks》. The information in the text is summarized as follows:

Diketopyrrolopyrrole and isoindigo are com. important dyes that have recently found broad application as electron acceptor and light-absorbing groups in organic semiconductors. Their self-assembly into specific supramol. structures to control optoelectronic properties has been hampered by limited options for substitution and their high propensity for crystallization Reported here is a mol. design that directs self-assembly into previously elusive columnar mesophases of π-π stacking cores. Although attachment of bis(trisoctyloxyphenyl)-1,3,5-triazine groups to both ends of diketopyrrolopyrrole-thiophene and isoindigo cores generated mesomorphic dyes of similar overall shapes and dimensions, distinct differences in their mesomorphism and optoelectronic properties were observed In the experiment, the researchers used many compounds, for example, 1-Bromo-3,4,5-trimethoxybenzene(cas: 2675-79-8Category: bromides-buliding-blocks)

Quality Control of 1-Bromo-3,4,5-trimethoxybenzene And the article was included in Molecules in 2020. The article conveys some information:

A convenient two-step preparation of NH-free 5-aryl-pyrrole-2-carboxylates is described. The synthetic route consists of catalytic borylation of com. available pyrrole-2-carboxylate ester followed by Suzuki coupling without going through pyrrole N-H protection and deprotection steps. The resulting 5-aryl substituted pyrrole-2-carboxylates were synthesized in good to excellent yields. This synthetic route can tolerate a variety of functional groups including those with acidic protons on the aryl bromide coupling partner. This methodol. is also applicable for cross-coupling with heteroaryl bromides to yield pyrrole-thiophene, pyrrole-pyridine, and 2,3′-bi-pyrrole based bi-heteroaryls.

In 2022,Liu, Jianming; Wang, Xiaopei; Wang, Zhiyue; Yang, Yan; Tang, Qinghu; Liu, Hongchi; Huang, Hanmin published an article in iScience. The title of the article was 《Unlocking a self-catalytic cycle in a copper-catalyzed aerobic oxidative coupling/cyclization reaction》.Category: bromides-buliding-blocks The author mentioned the following in the article:

A copper-catalyzed, aerobic oxidative C-H/C-H cyclization reaction, occurs by cleaving the C-H and N-H bonds of 3-phenylindoles, e.g., I. A broad range of 3-phenylindoles I can be well tolerated to produce the indole-containing polycyclic aromatic hydrocarbons (PAH), e.g., II in good to excellent yields. An evaluation of the reaction mechanism is enabled by the isolation of the di-, e.g., III and tri-indole intermediates, e.g., IV highlighting the role of the substrate for this catalytic reaction. The results of these controlled experiments and kinetic studies provide solid exptl. support for a self-catalysis reaction, which has rarely been observed in oxidative C-H activation reactions. Addnl. mechanistic studies indicate that the substrate for this reaction accelerates by the following mechanism: the substrate combines with the Cu catalyst to transform the less active di-indole intermediate into a tri-indole intermediate. This intermediate is quickly converted into the desired product along with regeneration of the substrate copper complex.

Synthetic Route of C9H11BrO3In 2021 ,《Rhodium-Catalyzed Regiodivergent Synthesis of Alkylboronates via Deoxygenative Hydroboration of Aryl Ketones: Mechanism and Origin of Selectivities》 was published in ACS Catalysis. The article was written by Zhang, Bing; Xu, Xin; Tao, Lei; Lin, Zhenyang; Zhao, Wanxiang. The article contains the following contents:

Here, authors report an efficient rhodium-catalyzed deoxygenative borylation of ketones to synthesize alkylboronates, in which the regioselectivity can be switched by the choice of the ligand. The linear alkylboronates were obtained exclusively in the presence of P(nBu)3, and PPh2Me favored the formation of branched alkylboronates. The protocol also allows access to 1,1,2-triboronates from the readily available ketones. Mechanistic studies suggest that this Rh-catalyzed deoxygenative borylation of ketones goes through an alkene intermediate, which undergoes regiodivergent hydroboration to afford linear and branched alkylboronates. The different steric effects of PPh2Me and P(nBu)3 were responsible for product selectivity by d. functional theory calculations The alkene intermediate can alternatively undergo sequential dehydrogenative borylation and hydroboration to deliver the triboronates.

Yuan, Tao; Zheng, Meifang; Antonietti, Markus; Wang, Xinchen published their research in Chemical Science in 2021. The article was titled 《Ceramic boron carbonitrides for unlocking organic halides with visible light》.COA of Formula: C9H11BrO3 The article contains the following contents:

Here, boron carbonitride (BCN) ceramics were such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradn was reported. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds was proceeded at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN was used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst showed tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opened new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which were metal-free, inexpensive and stable.

Ishikawa, Sekiha; Masuyama, Yoshikazu; Adachi, Takeshi; Shimonishi, Takeshi; Morimoto, Shotaro; Tanabe, Yoo published an article in 2021. The article was titled 《Synthesis of Naphthaleman Family Utilizing Regiocontrolled Benzannulation: Unique Molecules Composed of Multisubstituted Naphthalenes》, and you may find the article in ACS Omega.Category: bromides-buliding-blocks The information in the text is summarized as follows:

The naphthaleman family, a set of uniquely designed visual mol. structures comprising multisubstituted naphthalenes, I, wherein Yn = H, OMe, 3,4,5-(OMe)3, 1-naphthyl, was synthesized utilizing regiocontrolled benzannulation as a key step. The naphthaleman family possesses a common naphthalene body with a head comprising the 3,4-methylenedioxy group, sym. or unsym. right and left arms, and two alkynyl legs. The synthesis involves six C-C bond-forming reaction sequences. (i) syn-Stereoselective gem-dichlorocyclopropanation of Me angelate (86%). (ii) Acylation with ArMgBr (three examples, 60-91% yield). (iii) Stereocontrolled introduction of the 3,4-methylenedioxyphenyl group (three examples, 67-92% yield). (iv) Crucial regiocontrolled benzannulation to construct a common body segment (71-73% yield). (v) Two Suzuki-Miyaura cross-couplings to install the right or left arms (first-stage route: four examples, 77-93% and second-stage route: four examples, 42-90% yield). (vi) Double alkynylation to insert two legs (first-stage route: four examples, 61-77% yield and second-stage route: sole example, 83% yield). The four core members were produced through both first-stage and second-stage routes, with the second-stage approach demonstrating superiority over the first-stage approach. One of the members was alternatively synthesized by switching the installation order of the right and left arms, and identical twin members were produced by high-performance liquid chromatog. chiral separation The most stable conformations of two naphthaleman family members were calculated by Spartan software.

Computed Properties of C9H11BrO3In 2019 ,《Tetradentate platinum(II) complexes: Synthesis, photophysical properties, liquid crystalline characteristics and charge transport behaviour》 was published in Dyes and Pigments. The article was written by Zhao, Li; Yang, Bo; Zeng, Longwei; Luo, Kaijun; Wang, Haifeng; Ni, Hailiang; Yang, Congling; Li, Quan. The article contains the following contents:

Three new tetradentate phosphorescent Pt(II) complexes (Pt6, Pt12 and Pt16) with half-disk mol. structure were designed and synthesized, which are based on tetradentate ligands with six alkoxyl chains on the periphery, (6,6′-bis((3′,4′,5′-alkoxy-[1,1′-biphenyl]-4-yl)oxy)-2,2′-bipyridine). All complexes show red phosphorescence in dichloromethane solution (λem ≈ 640 nm) with quantum yields at 4.3-6.7% and phosphorescent lifetimes at 0.46-0.55 μs in degassed dichloromethane solution Among these complexes, the complex, Pt12, with 12 carbons chain lengths shows columnar mesophase with liquid crystal temperature range of – 22.0° to 77.8°, which was confirmed via polarized optical microscopy (POM), DSC and XRD. The complex, Pt12, exhibits ambipolar carrier transport behaviors, which was confirmed by the space charge limited current (SCLC) measurement. Moreover, the carrier mobility in mesogenic state is two orders of magnitudes greater than that in the amorphous state, showing ordering packing in liquid crystalline phase can facilitate the charge transport.

In 2022,Yan, Liwei; Saha, Ankur; Zhao, Wei; Neal, Jennifer F.; Chen, Yusheng; Flood, Amar H.; Allen, Heather C. published an article in Chemical Science. The title of the article was 《Recognition competes with hydration in anion-triggered monolayer formation of cyanostar supra-amphiphiles at aqueous interfaces》.Application of 2675-79-8 The author mentioned the following in the article:

The triggered self-assembly of surfactants into organized layers at aqueous interfaces is important for creating adaptive nanosystems and understanding selective ion extraction While these transformations require mol. recognition, the underlying driving forces are modified by the local environment in ways that are not well understood. Herein, we investigate the role of ion binding and ion hydration using cyanosurf, which is composed of the cyanostar macrocycle, and its binding to anions that are either size-matched or mis-matched and either weakly or highly hydrated. We utilize the supra-amphiphile concept where anion binding converts cyanosurf into a charged and amphiphilic complex triggering its self-organization into monolayers at the air-water interface. Initially, cyanosurf forms aggregates at the surface of a pure water solution When the weakly hydrated and size-matched hexafluorophosphate (PF6-) and perchlorate (ClO4-) anions are added, the macrocycles form distinct monolayer architectures. Surface-pressure isotherms reveal significant reorganization of the surface-active mols. upon anion binding while IR reflection absorption spectroscopy show the ion-bound complexes are well ordered at the interface. Vibrational sum frequency generation spectroscopy shows the water mols. in the interfacial region are highly ordered in response to the charged monolayer of cyanosurf complexes. Consistent with the importance of recognition, we find the smaller mis-matched chloride does not trigger the transformation. However, the size-matched phosphate (H2PO4-) also does not trigger monolayer formation indicating hydration inhibits its interfacial binding. These studies reveal how anion-selective recognition and hydration both control the binding and thus the switching of a responsive mol. interface.
