On May 31, 2019, Ruffoni, Alessandro; Julia, Fabio; Svejstrup, Thomas D.; McMillan, Alastair J.; Douglas, James J.; Leonori, Daniele published an article.Recommanded Product: 1-Fluoro-2-methoxybenzene The title of the article was Practical and regioselective amination of arenes using alkyl amines. And the article contained the following:

The formation of carbon-nitrogen bonds for the preparation of aromatic amines is among the top five reactions carried out globally for the production of high-value materials, ranging from from bulk chems. to pharmaceuticals and polymers. As a result of this ubiquity and diversity, methods for their preparation impact the full spectrum of chem. syntheses in academia and industry. In general, these mols. are assembled through the stepwise introduction of a reactivity handle in place of an aromatic C-H bond (i.e., a nitro group, halogen or boronic acid) and a subsequent functionalization or cross-coupling. Here we show that aromatic amines can be constructed by direct reaction of arenes and alkyl amines using photocatalysis, without the need for pre-functionalization. The process enables the easy preparation of advanced building blocks, tolerates a broad range of functionalities, and multigram scale can be achieved via a batch-to-flow protocol. The merit of this strategy as a late-stage functionalization platform has been demonstrated by the modification of several drugs, agrochems., peptides, chiral catalysts, polymers and organometallic complexes. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Recommanded Product: 1-Fluoro-2-methoxybenzene

On February 26, 2020, Kang, Qi-Kai; Lin, Yunzhi; Li, Yuntong; Shi, Hang published an article.HPLC of Formula: 321-28-8 The title of the article was Ru(II)-Catalyzed Amination of Aryl Fluorides via η6-Coordination. And the article contained the following:

A Ru/hemilabile-ligand catalyzed nucleophilic aromatic substitution (SNAr) of aryl fluorides as the limiting reagents was developed. Significant ligand enhancement was demonstrated by the engagement of both electron-rich and neutral arenes in the SNAr amination without using excess arenes. Preliminary mechanistic studies revealed that the nucleophilic substitution proceeds on a η6-complex of the Ru-catalyst and the substrate, and the hemilabile ligand facilitated dissociation of products from the metal center. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).HPLC of Formula: 321-28-8

And the article contained the following:

A regiodivergent C-H arylation of triphenylene derivatives with diaryliodonium salts was developed. The regiodivergence was controlled by electronic effects of diaryliodonium salts. When the aryl(mesityl)iodonium salts bearing strong electron-donating groups at the para-position of aryl groups were used, the arylation reactions occurred ortho to amide groups. However, if the aryl(mesityl)iodonium salts bearing electron-withdrawing groups or weak electron-donating groups at the para-position of aryl groups were utilized, the arylation reactions occurred meta to amide groups. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Name: 2-Methylanisole

On December 17, 2021, Song, Yan-Ling; Li, Bei; Xie, Zhen-Biao; Wang, Dan; Sun, Hong-Mei published an article.Related Products of 578-58-5 The title of the article was Iron-Catalyzed Oxidative Amination of Benzylic C(sp3)-H Bonds with Anilines. And the article contained the following:

Iron-catalyzed oxidative amination of benzylic C(sp3)-H bonds with anilines bearing electron-withdrawing groups (EWGs) or electron-donating groups (EDGs) has been realized based on simple variations of N-substituents on imidazolium cations in novel ionic Fe(III) complexes. The structural modification of the imidazolium cation resulted in regulation of the redox potential and the catalytic performance of the iron metal center. Using DTBP as oxidant, [HItBu][FeBr4] (1,3-di-tert-butylimidazolium iron tetrabromide) showed the highest catalytic activity for anilines bearing EWGs, while [HIPym][FeBr4] (1,3-bis(pyrimidin-2-yl)imidazolium iron tetrabromide) was more efficient for EDG-substituted anilines. This work provides an alternative access to benzylamines, e.g., RN(R1)CH2Ph [R = 4-O2NC6H4, 2-pyrimidinyl, 8-isoquinolinyl, etc., R1 = H, Me,], with advantages of both a wide substrate scope and iron catalysis. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Related Products of 578-58-5

On July 7, 2022, Misael, Wilken A.; Pean, Emmanuel V.; Borges, Bruno Gabriel A. L.; Mello, Gabriela da Cruz; Wouk, Luana; Davies, Matthew L.; Roman, Lucimara S.; Rocco, Maria Luiza M. published an article.Category: ethers-buliding-blocks The title of the article was Molecular Orientation and Femtosecond Electron Transfer Dynamics in Halogenated and Nonhalogenated, Eco-Friendly Processed PTB7-Th, ITIC, PTB7-Th:ITIC, and PTB7-Th:PCBM Films. And the article contained the following:

Synergistic effects of the electronic structure and morphol. in the PTB7-Th polymer and the nonfullerene acceptor ITIC mol. resulted in state-of-art systems for organic solar cells, achieving over 12% power conversion efficiency (PCE) values. Furthermore, the substitution of harmful halogenated solvents to environmentally friendly solvents that do not compromise PCE values has become a subject of great interest in recent literature. In this work, we employed sulfur K-edge Angle-Resolved Near-Edge X-ray Absorption Fine Structure, Resonant Auger Spectroscopy, and the core-hole clock spectroscopy in an attempt to gain information on the effect of different processing methods on the electronic and morphol. properties of these systems. Comparison with the PTB7-Th:PCBM blend, which uses a conventional acceptor mol., was also performed. Steady-state and time-resolved photoluminescence results were obtained for neat PTB7-Th and blends with ITIC and PCBM. Theor. calculations were performed utilizing restricted-excitation-window time-dependent d. functional theory. Our results shows that ortho-methylanisole is a potential replacement to the conventional halogenated solvent ortho-dichlorobenzene, as they show that in terms of morphol. and charge transfer dynamics, no expressive changes occurred by varying the solvent and by thermal annealing.

On December 31, 2020, Qiang, Hui; Chen, Tao; Wang, Zhuo; Li, Wenqian; Guo, Yunzhe; Yang, Jie; Jia, Xueshun; Yang, Hui; Hu, Weibo; Wen, Ke published an article.Recommanded Product: 1,4-Dimethoxybenzene The title of the article was Pillar[5]arene based conjugated macrocycle polymers with unique photocatalytic selectivity. And the article contained the following:

The development of heterogeneous catalysts with substrate shape, size or electronic constitution selectivity is a huge challenge in photocatalysis. Reported herein is a host-guest interaction strategy to endow photocatalysts with special selectivity. By adjusting the precursors, conjugated macrocycle polymers (CMPs) with pillar[5]arene struts (CMP-1 and CMP-2) and a corresponding non-pillar[5]arene-contained conjugated organic polymer (COP-1) were prepared and the photocatalytic activities toward sulfide derivatives were investigated. The sulfides showed similar conversions when COP-1 was used as a photocatalyst, but exhibited significant differences when it turned to the CMPs. Remarkably, the conversion yield of S-1 achieved near 18 folds over the one of S-2 when CMP-2 was used as a catalyst. Mechanism studies confirmed that the “host-guest” effect of pillar[5]arene struts in CMPs was the main cause of the difference. The present work establishes CMPs as novel heterogeneous photocatalysts with substrate selectivity, and such a method will inspire the researchers concerning preparation of heterogeneous catalysts with excellent selectivity.

On January 2, 2015, Mongin, Cedric; Pianet, Isabelle; Jonusauskas, Gediminas; Bassani, Dario M.; Bibal, Brigitte published an article.Category: ethers-buliding-blocks The title of the article was Supramolecular Photocatalyst for the Reduction of Au(III) to Au(I) and High-Turnover Generation of Gold Nanocrystals. And the article contained the following:

A photocatalyst composed of a diphenylanthracene core appended with two lipophilic thioether side-chains that binds gold(III) chloride is reported. Upon excitation using visible light, the AuIII ions are smoothly reduced to AuI which, in the presence of water, lead to the formation of crystalline gold nanoparticles of 20-50 nm diameter that are devoid of sulfur-containing capping agents. Ultrafast transient absorption spectroscopy shows that the anthracene excited state is quenched with a rate k = 3.5 × 1010 s-1, assigned to intramol. energy transfer to the bound gold ions, which then oxidizes the solvent to produce an intermediate low-valency gold(I) species. In the absence of water, the latter is stable and can be used as a homogeneous AuI catalyst. When employed in a biphasic reactor, the photocatalyst shows average turnover numbers of 150 atoms of AuIII reduced to Au0 per mol. of photocatalyst.

Sun, Guangping; Qian, Weirui; Jiao, Jianmin; Han, Tingting; Shi, Yukun; Hu, Xiao-Yu; Wang, Leyong published an article in 2020, the title of the article was A highly efficient artificial light-harvesting system with two-step sequential energy transfer based on supramolecular self-assembly.Name: 1,4-Dimethoxybenzene And the article contains the following content:

A highly efficient artificial light-harvesting system (ALHS) in the aqueous phase with a two-step sequential energy transfer process has been successfully constructed based on the host-guest interaction between a water-soluble pillar[5]arene (WP5) and a bola-type bis(4-phenyl)acrylonitrile derivative (BPT), as well as two different hydrophobic fluorescent dyes (4,7-bis(thien-2-yl)-2,1,3-benzothiadiazole (DBT) and Nile Red (NiR)). The fabricated ALHS shows an ultrahigh antenna effect (47.8 for the first step and 20.1 for the second step) with a high donor/acceptor ratio of 350 : 1. It is noted that the obtained WP5⊃BPT supramol. nanoparticles possess an enhanced aggregation-induced emission (AIE) effect and can function as an ideal donor to realize the first-step of energy transfer from the WP5⊃BPT assembly to DBT. Moreover, inspired by the sequential energy transfer in nature, NiR was carefully selected as the second acceptor to fabricate an efficient two-step sequential light-harvesting system based on the WP5⊃BPT-DBT-NiR assembly, which exhibits a high FRET efficiency of 60.9% and 89.4% for the two-step sequential energy transfer process, resp. Notably, the emission color changed from light blue to bright green and then to bright red during this process, and thus by tuning the molar ratio of DBT and NiR, a bright white light emission can be achieved with a high fluorescence quantum yield of 23.5%, which showed a strong ability for white fluorescence emission and promising applications in visible-light photocatalysis.
