Synthetic Route of C6H7NOIn 2020 ,《Ruthenium Catalyzed Divergent Alkylation and Olefination of Methyl 1,3,5-Triazines with Alcohols》 was published in European Journal of Organic Chemistry. The article was written by Su, Chengwu; Zeng, Ming; Zhang, Chen; Cui, Dong-Mei. The article contains the following contents:

An efficient ruthenium-catalyzed divergent alkylation and olefination of Me 1,3,5-triazines with alcs. have been developed. The selectivity can be rationally tuned by the judicious choice of ruthenium catalyst, wherein Ru(PPh3)3Cl2 delivers alkylated 1,3,5-triazines and RuCl3 gives olefinated 1,3,5-triazines in up to 98% yield. Following this simple, facile, and high atom economical protocol, a broad range of products was prepared in moderate to good yields and tolerated heterocyclic or benzylic alcs. containing functionalities. The overall transformation operates through dehydrogenation of primary alcs. under the reaction conditions to provide the corresponding aldehydes, which further undergo condensation with Me 1,3,5-triazines. The experimental part of the paper was very detailed, including the reaction process of 3-Pyridinemethanol(cas: 100-55-0Synthetic Route of C6H7NO)

Formula: C7H6O2In 2021 ,《RP-HPLC analysis of phenolic lignin monomers with DAD and coulometric array detection》 was published in Journal of Chromatographic Science. The article was written by Fischer, Klaus; Hoeffler, Susanne. The article contains the following contents:

An high performance liquid chromatog. (HPLC) method, applying diode array (DAD) and coulometric array detection simultaneously, was developed to determine monomeric phenolic compounds in lignin hydrolyzates. To allow for addnl. mass spectrometric detection, a formic acid gradient was designed as an alternative to the non-volatile phosphate buffer gradient. Within a total run time of 28 min, 10 out of 14 analytes were baseline separated by the formic acid gradient, and 8 compounds were completely resolved by the phosphate gradient. The dependence of the coulometric detection on cell potential, potential step width, eluent pH and eluent composition was comprehensively tested. Detection limits ≤20μg/L were achieved by DAD detection for nine analytes and by coulometric array detection for all analytes, demonstrating the superior sensitivity of electrochem. detection. DAD offered better linearity and reproducibility. Inter-day precision of peak heights spanned from 0.26 to 2.00% (formic acid gradient) and from 0.75 to 2.85% (phosphate buffer gradient) operating the DAD detector, but it exceeded 10% for several compounds applying the coulometric array detector. The simultaneous operation of both detectors offered an enhanced certainty of substance identification. The appropriateness of the method was confirmed by the anal. of various hydrolyzates of lignin-containing materials. The results came from multiple reactions, including the reaction of 3-Hydroxybenzaldehyde(cas: 100-83-4Formula: C7H6O2)

3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Formula: C7H6O2

The author of the article were Steele, W. Baylor; Kristofco, Lauren A.; Corrales, Jone; Saari, Gavin N.; Corcoran, Eric J.; Hill, Bridgett N.; Mills, Margaret G.; Gallagher, Evan; Kavanagh, Terrance J.; Melnikov, Fjodor; Zimmerman, Julie B.; Voutchkova-Kostal, Adelina; Anastas, Paul T.; Kostal, Jakub; Brooks, Bryan W.. The article conveys some information:

Sustainable mol. design of less hazardous chems. promises to reduce risks to public health and the environment. Computational chem. modeling coupled with alternative toxicol. models (e.g., larval fish) present unique high-throughput opportunities to understand structural characteristics eliciting adverse outcomes. Numerous environmental contaminants with reactive properties can elicit oxidative stress, an important toxicol. response associated with diverse adverse outcomes (i.e., cancer, diabetes, neurodegenerative disorders, etc.). We examined a common chem. mechanism (bimol. nucleophilic substitution (SN2)) associated with oxidative stress using property-based computational modeling coupled with acute (mortality) and sublethal (glutathione, photomotor behavior) responses in the zebrafish (Danio rerio) and the fathead minnow (Pimephales promelas) models to identify whether relationships exist among biol. responses and mol. attributes of industrial chems. Following standardized methods, embryonic zebrafish and larval fathead minnows were exposed sep. to eight different SN2 compounds for 96 h. Acute and sublethal responses were compared to computationally derived in silico chem. descriptors. Specifically, frontier MO energies were significantly related to acute LC50 values and photomotor response (PMR) no observed effect concentrations (NOECs) in both fathead minnow and zebrafish. This reactivity index, LC50 values, and PMR NOECs were also significantly related to whole body glutathione (GSH) levels, suggesting that acute and chronic toxicity results from protein adduct formation for SN2 electrophiles. Shared refractory locomotor response patterns among study compounds and two alternative vertebrate models appear informative of electrophilic properties associated with oxidative stress for SN2 chems. Electrophilic parameters derived from frontier MOs were predictive of exptl. in vivo acute and sublethal toxicity. These observations provide important implications for identifying and designing less hazardous industrial chems. with reduced potential to elicit oxidative stress through bimol. nucleophilic substitution. In addition to this study using 3-Bromopropan-1-ol, there are many other studies that have used 3-Bromopropan-1-ol(cas: 627-18-9Related Products of 627-18-9) was used in this study.

《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.

《Chemoselective Union of Olefins, Organohalides, and Redox-Active Esters Enables Regioselective Alkene Dialkylation》 was published in Journal of the American Chemical Society in 2020. These research results belong to Yang, Tao; Jiang, Yi; Luo, Yixin; Lim, Joel Jun Han; Lan, Yu; Koh, Ming Joo. Quality Control of 3-Bromopropan-1-ol The article mentions the following:

Multicomponent catalytic processes that can generate multiple C(sp3)-C(sp3) bonds in a single step under mild conditions, particularly those that employ inexpensive catalysts and substrates, are highly sought-after in chem. research for complex mol. synthesis. Here, we disclose an efficient Ni-catalyzed reductive protocol that chemoselectively merges alkenyl amides with two different aliphatic electrophiles. Starting materials are readily accessible from stable and abundant feedstock, and products are furnished in up to >98:2 regioisomeric ratios. The present strategy eliminates the use of sensitive organometallic reagents, tolerates a wide array of complex functionalities, and enables regiodivergent addition of two primary alkyl groups bearing similar electronic and steric attributes across aliphatic C=C bonds with exquisite control of site selectivity. Utility is underscored by the concise synthesis of bioactive compounds and postreaction functionalizations leading to structurally diverse scaffolds. DFT studies revealed that the regiochem. outcome originates from the orthogonal reactivity and chemoselectivity profiles of in situ generated organonickel species.

In 2019,Chemistry – A European Journal included an article by Timmer, Brian J. J.; Ramstroem, Olof. Name: 5-Hexen-1-ol. The article was titled 《Acid-Assisted Direct Olefin Metathesis of Unprotected Carbohydrates in Water》. The information in the text is summarized as follows:

The ability to use unprotected carbohydrates in olefin metathesis reactions in aqueous media is demonstrated. By using water-soluble, amine-functionalized Hoveyda-Grubbs catalysts under mildly acidic aqueous conditions, the self-metathesis of unprotected alkene-functionalized α-D-manno- and α-D-galactopyranosides could be achieved through minimization of non-productive chelation and isomerization. Cross-metathesis with allyl alc. could also be achieved with reasonable selectivity. The presence of small quantities (2.5 vol %) of acetic acid increased the formation of the self-metathesis product while significantly reducing the alkene isomerization process. These results demonstrate the potential of directly using unprotected carbohydrate structures in olefin metathesis reactions under mild conditions compatible with biol. systems, and thereby enabling their use in, for example, drug discovery and protein derivatization. In the experimental materials used by the author, we found 5-Hexen-1-ol(cas: 821-41-0Name: 5-Hexen-1-ol)
