UV light promoted selective oxidation of primary and secondary alcs. RCH(R1)OH [R = Ph, cyclohexyl, thiophen-2-yl, etc.; R1 = H, Ph, Me; RR1 = -(CH2)5-], 1,3-benzenedimethanol and 9H-fluoren-9-ol has been demonstrated under ‘metal-free’ and ‘additive-free’ conditions. Under the optimized conditions, a variety of aromatic, heteroaromatic, and alicyclic alcs. have been examined for their transformations to the corresponding carbonyl compounds RC(O)R1, isophthalaldehyde and 9H-fluoren-9-one. The mechanistic studies emphasize the important role of substrate (alc.) and solvent (DMSO) in the generation of superoxide radical which is a vital intermediate for the transformation. This study also highlights the role of air as the oxidant in the oxidation process. Further, the practical application of the strategy has also been demonstrated for the oxidation of the alc. moiety in cholesterol. In addition to this study using (4-Bromophenyl)methanol, there are many other studies that have used (4-Bromophenyl)methanol(cas: 873-75-6Related Products of 873-75-6) was used in this study.

And the article was published in Organometallics in 2019. Quality Control of (4-Bromophenyl)methanol The author mentioned the following in the article:

The application of nontoxic, earth-abundant transition metals in place of costly noble metals is a paramount goal in catalysis and is especially interesting if the air- and moisture-stable ligand scaffold was used. Herein, the authors report the synthesis of amines/imines directly from alc. and amines via H autotransfer or acceptorless dehydrogenation catalyzed by well-defined phosphine-free Mn complexes. Both imines and amines can be obtained from the same set of alcs. and amines using the same catalyst, only by tuning the reaction conditions. The amount and nature of the base are a highly important aspect for the observed selectivity. Both the primary and secondary amines were employed as substrates for the N-alkylation reaction. As a highlight, the authors showed the chemoselective synthesis of resveratrol derivatives Also, the Mn-catalyzed dehydrogenative synthesis of structurally important 2,3-dihydro-1H-perimidines also was demonstrated. D. functional theory calculations were also carried out to model the reaction path and to calculate the reaction profile.

And the article was published in Nature Communications in 2019. Formula: C7H7BrO The author mentioned the following in the article:

Metal nanoparticles (NPs) stabilized by metal-organic frameworks (MOFs) have been intensively studied in recent decades, while investigations on the location of guest metal NPs relative to host MOF particles remain challenging and very rare. In this work, we have developed several characterization techniques, including high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) tomog., hyperpolarized 129Xe NMR spectroscopy and positron annihilation spectroscopy (PAS), which are able to determine the specific location of metal NPs relative to the MOF particle. The fine PdCu NPs confined inside MIL-101 exhibit excellent catalytic activity, absolute selectivity and satisfied recyclability in the aerobic oxidation of benzyl alc. in pure water. As far as we know, the determination for the location of metal NPs relative to MOF particles and pore structure information of metal NPs/MOF composites by 129Xe NMR and PAS techniques has not yet been reported.

《Introduction of a trinuclear manganese(III) catalyst on the surface of magnetic cellulose as an eco-benign, efficient and reusable novel heterogeneous catalyst for the multi-component synthesis of new derivatives of xanthene》 was written by Ghamari kargar, Pouya; Bagherzade, Ghodsieh; Eshghi, Hossein. Related Products of 873-75-6This research focused ontrinuclear manganese nanocatalyst preparation; xanthene green preparation; aldehyde dimedone three component trinuclear manganese nanocatalyst; carbonyl compound green preparation; alc oxidation trinuclear manganese nanocatalyst. The article conveys some information:

In this work, the new trinuclear manganese catalyst defined as Fe3O4@NFC@NNSM-Mn(III) was successfully manufactured and fully characterized by different techniques, including FT-IR, XRD, TEM, SEM, EDX, VSM, and ICP anal. This magnetic catalysts used for the synthesis of xanthene derivatives I [R = Ph, 4-ClC6H4, 1H-indol-3-yl, etc.; R1 = H, Me]. The critical potential interest in the present method included short reaction time, high yields, recyclability of the catalyst, easy workup and ability to sustain a variety of functional groups, which gave economical as well as ecol. rewards. Also, the synthesized catalyst was used as a recyclable trinuclear catalyst for synthesis of carbonyl compounds via alc. oxidation reactions at 40°C. The magnetic catalyst activity of Fe3O4@NFC@NNSM-Mn(III) could be attributed to the synergistic effects of the catalyst Fe3O4@NFC@NNS-Mn(III) with melamine. Employing a sustainable and safe low temperature, using an eco-friendly solvent, no need to use any additive, and long-term stability and magnetic recyclability of the catalyst for at least six successive runs were the advantages of current protocol toward green chem. This protocol was a benign, environmentally friendly method for heterocycle synthesis.

The author of 《Immobilization of manganese dioxide nanoparticles on modified poly 2,4-dichlorostyrene microspheres: a highly efficient and recyclable catalyst for borrowing hydrogen reactions》 were Qiu, Ye; Zhang, Yilin; Jin, Lu; Pan, Le; Du, Guangming; Ye, Dongdong; Wang, Dawei. And the article was published in Organic Chemistry Frontiers in 2019. SDS of cas: 873-75-6 The author mentioned the following in the article:

Manganese dioxide nanoparticles have been fabricated using a facile approach and immobilized onto the surface of modified poly 2,4-dichlorostyrene microspheres. The resulting multifunctional hybrid materials were characterized by SEM, transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray power diffraction and X-ray photoelectron spectrometry. This cheap heterogeneous manganese catalyst revealed excellent reactivity and stability for the direct alkylation of primary alcs. with ketones via a hydrogen borrowing pathway. In addition, this catalytic system could be readily recycled more than five times with high reactivity retained, which provided a practical atom-economical approach for C-C bond formation and 1-benzyl-2-aryl-1H-benzo[d]imidazole synthesis. Mechanism investigations were conducted to better understand this catalyst system and these transformations.

In 2019,Organometallics included an article by Eberhardt, Nathan A.; Wellala, Nadeesha P. N.; Li, Yingze; Krause, Jeanette A.; Guan, Hairong. Safety of (4-Bromophenyl)methanol. The article was titled 《Dehydrogenative Coupling of Aldehydes with Alcohols Catalyzed by a Nickel Hydride Complex》. The information in the text is summarized as follows:

A nickel hydride complex, {2,6-(iPr2PO)2C6H3}NiH, has been shown to catalyze the coupling of RCHO and R’OH to yield RCO2R’ and RCH2OH, where the aldehyde also acts as a hydrogen acceptor and the alc. also serves as the solvent. Functional groups tolerated by this catalytic system include CF3, NO2, Cl, Br, NHCOMe, and NMe2, whereas phenol-containing compounds are not viable substrates or solvents. The dehydrogenative coupling reaction can alternatively be catalyzed by an air-stable nickel chloride complex, {2,6-(iPr2PO)2C6H3}NiCl, in conjunction with NaOMe. Acids in unpurified aldehydes react with the hydride to form nickel carboxylate complexes, which are catalytically inactive. Water, if present in a significant quantity, decreases the catalytic efficiency by forming {2,6-(iPr2PO)2C6H3}NiOH, which causes catalyst degradation On the other hand, in the presence of a drying agent, {2,6-(iPr2PO)2C6H3}NiOH generated in situ from {2,6-(iPr2PO)2C6H3}NiCl and NaOH can be converted to an alkoxide species, becoming catalytically competent. The proposed catalytic mechanism features aldehyde insertion into the nickel hydride as well as into a nickel alkoxide intermediate, both of which have been exptl. observed Several mechanistically relevant nickel species including {2,6-(iPr2PO)2C6H3}NiOC(O)Ph, {2,6-(iPr2PO)2C6H3}NiOPh, and {2,6-(iPr2PO)2C6H3}NiOPh·HOPh have been independently synthesized, crystallog. characterized, and tested for the catalytic reaction. While phenol-containing mols. cannot be used as substrates or solvents, both {2,6-(iPr2PO)2C6H3}NiOPh and {2,6-(iPr2PO)2C6H3}NiOPh·HOPh are efficient in catalyzing the dehydrogenative coupling of PhCHO with EtOH.
