《Mechanistic insight into the azo radical-promoted dehydrogenation of heteroarene towards N-heterocycles》 was written by Bains, Amreen K.; Adhikari, Debashis. Electric Literature of C7H7BrOThis research focused ontriazine pyrimidine preparation mechanism kinetics; alc amidine hydrochloride dehydrogenation nickel catalyst. The article conveys some information:

Herein, a molecularly defined nickel catalyst, which can perform two annulation reactions under mild conditions (80°, 8 h), towards the sustainable synthesis of triazine I (R = H, 4-Me, 4-F, etc.) and pyrimidine II (R = H, 4-Me, 2-F, etc.; R1 = Me, C6H5, 4-MeC6H4, 4-FC6H4) has been reported. Mechanistically, the important role of the catalyst in promoting the dehydrogenation of heteroarenes is clearly described. The binding of the saturated heterocycle to the metal catalyst underwent a pre-equilibrium step (K = 238 at 80°), which is followed by a crucial hydrogen atom transfer. A series of kinetics experiments including Van’t Hoff, Eyring anal. and interception of pyrimidinyl radical disclosed the details of the dehydrogenation process. This ligand-driven, base metal catalytic approach is significantly different from the considerably evaluated metal-ligand cooperative bond activation strategies, which may offer an alternative dehydrogenation pathway that demands less energy.(4-Bromophenyl)methanol(cas: 873-75-6Electric Literature of C7H7BrO) was used in this study.

COA of Formula: C7H7BrO The article mentions the following:

The combination of an organic photocatalyst [4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene) or 5MeOCzBN (2,3,4,5,6-pentakis(3,6-dimethoxy-9 H-carbazol-9-yl)benzonitrile)], quinuclidine, and tetra-n-butylammonium phosphate (hydrogen-bonding catalyst) was employed for amide bond formations. The hydrogen-bonded OH group activated the adjacent C-H bond of alcs. towards hydrogen atom transfer (HAT) by a radical species. The quinuclidinium radical cation, generated through single-electron oxidation of quinuclidine by the photocatalyst, employed to abstract a hydrogen atom from the α-C-H bond of alcs. selectively due to a polarity effect-produced α-hydroxyalkyl radical, which subsequently converted to the corresponding aldehyde under aerobic conditions. Then the coupling of the aldehyde and an amine formed a hemiaminal intermediate that upon photocatalytic oxidation produced the amide.

Hosseini, Seyed Mohammad; Karimi, Meghdad; Safarifard, Vahid published an article in 2021. The article was titled 《Metal-organic framework/carbon nitride nanosheets composites (TMU-49/CNNSs): efficient photocatalyst for aerobic oxidation of alcohols under visible light》, and you may find the article in New Journal of Chemistry.Formula: C7H7BrO The information in the text is summarized as follows:

Oxidation reactions are considered as a challenging issue at the industrial scale. As several traditional methods are not biocompatible and safe, there is a need to develop sustainable photocatalytic approaches that employ mol. oxygen as the terminal oxidant. Herein, a cobalt-based metal-organic framework (MOF) was hybridized with graphitic carbon nitride nanosheets (CNNSs), namely TMU-49/CNNSs, using a facile in situ ultrasound-assisted synthesis, for the catalytic photo-oxidation of benzyl alc. under visible light irradiation The oxidation was carried out with variation of four parameters: solvent, catalyst amount, time and light source. Characterization of as-prepared samples was performed by Fourier-transform IR spectroscopy, thermogravimetric anal., X-ray powder diffraction, N2 adsorption-desorption, SEM, and UV-visible diffuse reflection spectra. The TMU-49/CNNSs composite exhibited remarkable photocatalytic activity under visible light irradiation; the oxidation yield reached almost 80% for benzyl alc. after 3 h reaction. The superior photocatalytic activity of the MOF/CNNSs composite is attributed to enhanced separation of the photogenerated electron-hole pairs and increased visible-light absorption. After reading the article, we found that the author used (4-Bromophenyl)methanol(cas: 873-75-6Formula: C7H7BrO)

《Efficient aerial oxidation of different types of alcohols using ZnO nanoparticle-MnCO3-graphene oxide composites》 was published in Applied Organometallic Chemistry in 2020. These research results belong to Adil, Syed Farooq; Assal, Mohamed E.; Shaik, Mohammed Rafi; Kuniyil, Mufsir; Hashmi, Azhar; Khan, Mujeeb; Khan, Aslam; Tahir, Muhammad Nawaz; Al-Warthan, Abdulrahman; Siddiqui, Mohammed Rafiq H.. Synthetic Route of C7H7BrO The article mentions the following:

In this study, nanocomposites of graphene oxide (GRO) and ZnO nanoparticle-doped MnCO3 ([ZnO-MnCO3/(1%)GRO]) were synthesized via a facile, straightforward co-precipitation technique. Interestingly, it was noticed that the incorporation of GRO in the catalytic system could noticeably improve the catalytic efficiency compared to a catalyst (ZnO-MnCO3) without GRO, for aerial oxidation of benzyl alc. (BzOH) employing O2 as a nature-friendly oxidant under base-free conditions. The impacts of various reaction factors were thoroughly explored to optimize reaction conditions using oxidation of BzOH to benzaldehyde (BzH) as a model substrate. The catalysts were characterized using X-ray diffraction, thermogravimetric anal., Fourier transform IR spectroscopy, field-emission SEM, Energy dispersive X-ray spectroscopy (EDX), Brunauer-Emmett-Teller (BET), and Raman spectroscopy. The (1%)ZnO-MnCO3/(1%)GRO exhibited significant specific activity (67 mmol.g-1.hr-1) with full conversion of BzOH and >99% BzH selectivity within just 6 min. The catalytic efficiency of the (1%)ZnO-MnCO3/(1%)GRO nanocomposite was significantly better than the (1%)ZnO-MnCO3/(1%)HRG and (1%)ZnO-MnCO3 catalysts, presumably due to the existence of oxygen-possessing groups on the GRO surface and as well as a very high surface area that could have been instrumental in uniformly dispersing the active sites of the catalyst, i.e., ZnO-MnCO3. Under optimum circumstances, various kinds of alcs. ROH (R = benzyl, furan-2-ylmethyl, cyclohexyl, 1-phenylethyl, etc.) were selectively transformed to resp. carbonyls, e.g., cyclohexanone with full convertibility over the (1%)ZnO-MnCO3/(1%)GRO catalyst. Furthermore, the highly effective (1%)ZnO-MnCO3/(1%)GRO catalyst could be successfully reused and recycled over five consecutive runs with a marginal reduction in its performance and selectivity.(4-Bromophenyl)methanol(cas: 873-75-6Synthetic Route of C7H7BrO) was used in this study.

《Fabrication of a new heterogeneous tungstate-based on the amino-functionalized metal-organic framework as an efficient catalyst towards sonochemical oxidation of alcohols under green condition》 was written by Sabaghi, Maryam; Aghajani, Zahra; Najafi, Gholam Reza. Computed Properties of C7H7BrOThis research focused ontungstate amino functionalized metal organic framework catalyst preparation; aldehyde ketone preparation green chem ultrasound irradiation; alc sonochem oxidation. The article conveys some information:

Ultrasonic-assisted reactions, as a green technique, are often more efficient compared to those traditional protocols. To this end, the selective and solvent-free oxidation of aromatic alcs. to the corresponding aldehydes and ketones were investigated in the presence of Co-ABDC/W at room temperature under ultrasonic irradiation conditions for the first time in this paper. The structure, particle size, thermal stability, and morphol. of the fabricated heterogeneous catalyst and the products were characterized by FT-IR, EDS, FE-SEM, XRD, TGA, and GC analyses. In this regard, immobilization of tungstate had a significant effect on thermal stability (around 450° for 40% weight loss) and catalytic performance. Moreover, the efficiency of two different oxidation methods, including ultrasound irradiations and reflux, were comparatively investigated by GC spectrometry. Obtained sonoxidn. results presented higher conversions ranging (84 to 100%) than reflux condition via shorter reaction times. The influences of the reaction parameters, such as hydrogen peroxide concentration, and catalyst loading, were also investigated. The proposed method offers several advantages, such as excellent conversions, selective oxidations, environmentally-benign procedure, short reaction times, and easy workup. Notably, this is the first report that focuses on using amino-functionalized MOFs with ultrasonic irradiation for selective oxidation reactions. The experimental part of the paper was very detailed, including the reaction process of (4-Bromophenyl)methanol(cas: 873-75-6Computed Properties of C7H7BrO)
