Recommanded Product: 873-75-6 And the article was included in ACS Sustainable Chemistry & Engineering in 2020. The article conveys some information:

Heteroatom doping in nanomaterials can import new active sites and promote catalytic activity. Here we report that Mn-doped Co3O4 nanorods (Mnx-Co3O4) via substituting Mn3+ (t2g3-eg1) for Co3+ (t2g6-eg0) exhibit ~100% yield for 4-Me benzyl alc. dehydrogenation catalysis at 60°C and no decay (8 cycles), compared with only 1.4% of activity for bare Co3O4 catalysts. We characterize the fine structures of Mnx-Co3O4 at the at. level and demonstrate that the superior catalytic performance is strongly related to the Mn3+-induced Jahn-Teller (J-T) effect, which is a geometric distortion that has generally been considered to be disadvantageous for applications. Exptl. observations and theor. calculations reveal that unsaturated Mn3+ with J-T distortion acts as an active site, and readily reacts with -OH groups of benzyl alc. adsorbed nearby, simultaneously promoting dehydrogenation to directly yield benzaldehyde. Mnx-Co3O4 catalysts rapidly dehydrogenate alcs. into aldehydes/ketones for 19 reactions with >99.9% selectivity and 14 examples with >90.2% yield. Mn3+-induced Jahn-Teller effect in Mn-doped Co3O4 catalyst promotes sustainable catalytic dehydrogenation of alcs.

Senthilkumar, Samuthirarajan; Zhong, Wei; Natarajan, Mookan; Lu, Chunxin; Xu, Binyu; Liu, Xiaoming published an article in 2021. The article was titled 《A green approach for aerobic oxidation of benzylic alcohols catalysed by CuI-Y zeolite/TEMPO in ethanol without additional additives》, and you may find the article in New Journal of Chemistry.Computed Properties of C7H7BrO The information in the text is summarized as follows:

An efficient and green protocol for aerobic oxidation of benzylic alcs. in ethanol using CuI-Y zeolite catalysts assisted by TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidine-N-oxyl) as the radical co-catalyst in the presence of atm. air under mild conditions is reported. The CuI-Y zeolite prepared via ion exchange between CuCl and HY zeolite was fully characterized by a variety of spectroscopic techniques including XRD, XPS, SEM, EDX and HRTEM. The incorporation of Cu(I) into the 3D-framework of the zeolite rendered the catalyst with good durability. The results of repetitive runs revealed that in the first three runs, there was hardly a decline in activity and a more substantial decrease in yield was observed afterwards, while the selectivity remained almost unchanged. The loss in activity was attributed to both the formation of CuO and the bleaching of copper into the liquid phase during the catalysis, of which the formation of CuO was believed to be the major contributor since the bleaching loss for each run was negligible (<2%). In this catalytic system, except TEMPO, no other additives were needed, either a base or a ligand, which was essential in some reported catalytic systems for the oxidation of alcs. The aerobic oxidation proceeded under mild conditions (60°C, and 18 h) to quant. and selectively convert a wide range of benzylic alcs. to corresponding aldehydes, which shows great potential in developing green and environmentally benign catalysts for aerobic oxidation of alcs. The system demonstrated excellent tolerance against electron-withdrawing groups on the Ph ring of the alcs. and showed sensitivity to steric hindrance of the substrates, which is due to the confinement of the pores of the zeolite in which the oxidation occurred. Based on the mechanism reported in the literature for homogenous oxidation, a mechanism was analogously proposed for the aerobic oxidation of benzylic alcs. catalyzed by this Cu(I)-containing zeolite catalyst. The experimental part of the paper was very detailed, including the reaction process of (4-Bromophenyl)methanol(cas: 873-75-6Computed Properties of C7H7BrO)

Quality Control of (4-Bromophenyl)methanolIn 2020 ,《Room-Temperature Guerbet Reaction with Unprecedented Catalytic Efficiency and Enantioselectivity》 was published in Angewandte Chemie, International Edition. The article was written by Ng, Teng Wei; Liao, Gang; Lau, Kai Kiat; Pan, Hui-Jie; Zhao, Yu. The article contains the following contents:

The authors report herein an unprecedented highly efficient Guerbet-type reaction at room temperature (catalytic TON up to >6000). This β-alkylation of secondary Me carbinols with primary alcs. has significant advantage of delivering higher-order secondary alcs. in an economical, redox-neutral fashion. In addition, the first enantioselective Guerbet reaction also was achieved using a com. available chiral ruthenium complex to deliver secondary alcs. with moderate yield and up to 92% ee. In both reactions, the use of a traceless ketone promoter proved to be beneficial for the catalytic efficiency.

And the article was published in Journal of the American Chemical Society in 2019. Electric Literature of C7H7BrO The author mentioned the following in the article:

Photocatalytic selective oxidation reactions hold great promise for the design of high-value-added organic intermediates, but many of these reactions suffer from low conversion efficiency and selectivity due to uncontrollable oxidation processes. In view of using photogenerated reactive oxygen species as the key oxidant in a selective oxidation reaction, we propose that a highly selective oxidation reaction can be achieved by modulating the corresponding photocatalytic mol. oxygen (O2) activation processes. Using cubic indium sulfide (β-In2S3) nanosheets as a model system, we show that the charge carriers involved in O2 activation can be optimized with the introduction of surface S vacancies. Benefiting from the enhanced charge separation and transfer processes, the In2S3 nanosheets with S vacancies could simultaneously activate O2 into superoxide radicals via electron transfer under visible-light irradiation to display outstanding activity for the selective oxidation of alcs. to aldehydes with high conversion and selectivity. This study offers a new strategy to optimize photocatalytic selective oxidation reactions.

In 2019,Journal of the American Chemical Society included an article by Kang, Zhenghui; Wang, Yongheng; Zhang, Dan; Wu, Ruibo; Xu, Xinfang; Hu, Wenhao. Safety of (4-Bromophenyl)methanol. The article was titled 《Asymmetric Counter-Anion-Directed Aminomethylation: Synthesis of Chiral β-Amino Acids via Trapping of an Enol Intermediate》. The information in the text is summarized as follows:

In the presence of allylpalladium chloride dimer and a penta-(-)-menthyl cyclopentadienepentacarboxylate, diazo esters such as PhC(:N2)CO2Me underwent enantioselective three-component aminomethylation reactions with alcs. such as benzyl alc. and (methoxymethyl)amines such as MeOCH2NBn2 (Bn = PhCH2) to yield nonracemic α-alkoxy-β-amino esters such as I. The mechanism of the reaction was studied using in-situ generated intermediates and DFT calculations; the reaction likely occurs by stereoselective trapping of an in situ-generated enol with an iminium ion through hydrogen bonding and electrostatic interactions with a nonracemic pentacarboxycyclopentadiene anion.

《Chromium-Catalyzed Alkylation of Amines by Alcohols》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Kallmeier, Fabian; Fertig, Robin; Irrgang, Torsten; Kempe, Rhett. HPLC of Formula: 873-75-6 The article mentions the following:

The alkylation of amines by alcs. is a broadly applicable, sustainable, and selective method for the synthesis of alkyl amines, which are important bulk and fine chems., pharmaceuticals, and agrochems. We show that Cr complexes can catalyze this C-N bond formation reaction. We synthesized and isolated 35 examples of alkylated amines, including 13 previously undisclosed products, and the use of amino alcs. as alkylating agents was demonstrated. The catalyst tolerates numerous functional groups, including hydrogenation-sensitive examples. Compared to many other alc.-based amine alkylation methods, where a stoichiometric amount of base is required, our Cr-based catalyst system gives yields higher than 90% for various alkyl amines with a catalytic amount of base. Our study indicates that Cr complexes can catalyze borrowing hydrogen or hydrogen autotransfer reactions and could thus be an alternative to Fe, Co, and Mn, or noble metals in (de)hydrogenation catalysis.(4-Bromophenyl)methanol(cas: 873-75-6HPLC of Formula: 873-75-6) was used in this study.

The first iron(II)-catalyzed biomimetic aerobic oxidation of alcs was reported. The principle of this oxidation, which involved several electron-transfer steps, was reminiscent of biol. oxidation in respiratory chain. The electron transfer from alc. to mol. oxygen occurred with aid of three coupled catalytic redox systems, led to a low-energy pathway. An iron transfer-hydrogenation complex was utilized as a substrate-selective dehydrogenation catalyst, along with an electron-rich quinone and an oxygen-activating Co(salen)-type complex as electron-transfer mediators. Various primary and secondary alcs. were oxidized in air to the corresponding aldehydes or ketones with this method in good to excellent yields. In the part of experimental materials, we found many familiar compounds, such as (4-Bromophenyl)methanol(cas: 873-75-6COA of Formula: C7H7BrO)

《Nickel-catalysed chemoselective C-3 alkylation of indoles with alcohols through a borrowing hydrogen method》 was written by Bains, Amreen K.; Biswas, Ayanangshu; Adhikari, Debashis. COA of Formula: C7H7BrO And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020. The article conveys some information:

An inexpensive, air-stable, isolable nickel catalyst is reported that can perform chemoselective C3-alkylation of indoles with a variety of alcs. following “”borrowing hydrogen””. A one-pot, cascade C3-alkylation starting from 2-aminophenyl Et alcs., and thus obviating the need for pre-synthesized indoles, further adds to the broad scope of this method. The reaction is radical-mediated, and is significantly different from other examples, often dictated by metal-ligand bifunctionality. In the experiment, the researchers used many compounds, for example, (4-Bromophenyl)methanol(cas: 873-75-6COA of Formula: C7H7BrO)
