Li, Xiaojiang; Sun, Leitao; Lv, Xin; Qi, Jie; Lu, Hongsheng; Wu, Yuanpeng; wang, Baogang published an article in 2021. The article was titled 《Sustainable separation of petroleum hydrocarbons pollutant using hydrophobic deep eutectic solvents regulated by CO2》, and you may find the article in Journal of Environmental Chemical Engineering.HPLC of Formula: 150-19-6 The information in the text is summarized as follows:

Petroleum hydrocarbons pollutants are the serious environmental hazards in the exploitation of petroleum resources. As comparison to the traditional solvent for petroleum hydrocarbons removal, deep eutectic solvents (DESs), as the ideal alternate for organic solvents, have non-toxicity, non-flammability and lower volatility. Whereas, the recycling of DES is still the great challenge for sustainable separation Herein, hydrophobic DESs (HDESs) with the CO2 switchable-hydrophilicity are developed, aiming to sustainably sep. petroleum hydrocarbons pollutions. The HDESs are formed by hydrogen bonds between the phenolic compounds as hydrogen bond donors (HBDs) and tertiary amines as hydrogen bond acceptors (HBAs), which was demonstrated by the spectroscopic detection. Interestingly, the HDES exhibits better CO2 -switchable behavior than traditional switchable-solvent, where the phase transition is induced by the protonation of HBA upon CO2and the deprotonation of HBD in HCO-3 solution of HBA. Furthermore, the sustainable separation for oils (heptane, diesel oil and crude oil) is successfully completed, and the HDES is also easily recovered upon N2/65°C. Finally, the HDES is effectively applied in removing petroleum hydrocarbons from oily wastes (oil sands and oily sludge). The results show that more than 98% oil is removed from oil sands, and 85.02% oil is also removed from oily sludge. Thus, the HDESs will be expected to treated as the effective extractant for sustainable and cleaner separation of petroleum hydrocarbons- contaminated waste.

Roscales, Silvia; Csaky, Aurelio G. published an article in 2021. The article was titled 《Synthesis of Ketones by C-H Functionalization of Aldehydes with Boronic Acids under Transition-Metal-Free Conditions》, and you may find the article in Angewandte Chemie, International Edition.COA of Formula: C9H10O2 The information in the text is summarized as follows:

A method for the synthesis of ketones from aldehydes and boronic acids via a transition-metal-free C-H functionalization reaction is reported. The method employs nitrosobenzene as a reagent to drive the simultaneous activation of the boronic acid as a boronate and the activation of the C-H bond of the aldehyde as an iminium species that triggers the key C-C bond-forming step via an intramol. migration from boron to carbon. These findings constitute a practical, scalable, and operationally straightforward method for the synthesis of ketones.2-(Benzyloxy)acetaldehyde(cas: 60656-87-3COA of Formula: C9H10O2) was used in this study.

《Synthesis and Functionalization of Allenes by Direct Pd-Catalyzed Organolithium Cross-Coupling》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Mateos-Gil, Jaime; Mondal, Anirban; Castineira Reis, Marta; Feringa, Ben L.. Computed Properties of C7H7BrO The article mentions the following:

A palladium-catalyzed cross-coupling between in situ generated allenyl/propargyl-lithium species and aryl bromides to yield highly functionalized allenes is reported. The direct and selective formation of allenic products preventing the corresponding isomeric propargylic product is accomplished by the choice of SPhos or XPhos based Pd catalysts. The methodol. avoids the prior transmetalation to other transition metals or reverse approaches that required prefunctionalization of substrates with leaving groups, resulting in a fast and efficient approach for the synthesis of tri- and tetrasubstituted allenes. Exptl. and theor. studies on the mechanism show catalyst control of selectivity in this allene formation. In the experimental materials used by the author, we found 1-Bromo-3-methoxybenzene(cas: 2398-37-0Computed Properties of C7H7BrO)

The author of 《Structural analysis and biological functionalities of iron(III)- and manganese(III)-thiosemicarbazone complexes: in vitro anti-proliferative activity on human cancer cells, DNA binding and cleavage studies》 were Kaya, Busra; Yilmaz, Zehra Kubra; Sahin, Onur; Aslim, Belma; Tukenmez, Ummugulsum; Ulkuseven, Bahri. And the article was published in JBIC, Journal of Biological Inorganic Chemistry in 2019. Formula: C8H8O3 The author mentioned the following in the article:

One iron(III) and two manganese(III) complexes based on thiosemicarbazone were synthesized and characterized using anal. and spectroscopic data. The crystallog. anal. showed the square pyramid structures of the complexes. Electronic spectra anal. was performed to determine the nature of the interaction between the complexes and calf thymus DNA (CT-DNA). DNA cleavage activities of the complexes were examined by gel electrophoresis (pBR322 DNA). The cytotoxicity of the complexes was determined against human cervical carcinoma (HeLa) and human colorectal adenocarcinoma (HT-29) cell lines by MTT assay. The results indicated that complex Fe1(I) is bound to CT-DNA via the intercalation mode, while complexes Mn1(II) and Mn2(III) are bound to CT-DNA via groove binding and/or electrostatic interactions rather than the intercalation mode. In addition, they showed good binding activity, which followed the order of I > III > II. Complexes were found to promote the cleavage of DNA from supercoiled form (SC, Form I) to nicked circular form (NC, Form II) without concurrent formation of Form III, revealing the single-strand DNA cleavage. No significant cleavage was found in the presence of II and III; however, it was observed at 2000 and 3000μM concentrations of I. The ability of I to cleave DNA was greater than that of other complexes and these results are in conformity with their DNA-binding affinities. Cytotoxicity determination tests revealed that the complex I on HeLa and HT-29 cells exhibited a higher anti-proliferative effect than II and III (I > III > II). These studies suggested that the complex I could be a good candidate as a chemotherapeutic drug targeting DNA. In the experiment, the researchers used many compounds, for example, 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Formula: C8H8O3)

A highly enantioselective dicarbofunctionalization of unactivated alkenes was implemented by a Pd-catalyzed asym. tandem Heck/Suzuki coupling reaction. This reaction represents the first example of a highly enantioselective intramol. cyclization/cross-coupling of olefin-tethered aryl halides with alkyl-, alkenyl- or arylboronic acids, and provides rapid access to a number of chiral compounds, such as dihydrobenzofurans, indolines, chromanes, and indans bearing a quaternary stereocenter, in good yields with excellent enantioselectivities. The practicality of this reaction was validated in the modification of biol. complex mols. such as peptides, piperitol, CB2 receptor agonists, etc. Moreover, the synthesis of two enantiomers can be easily realized by simple change in the order of the steps in the coupling sequence.

In 2019,Journal of the American Chemical Society included an article by Mills, L. Reginald; Graham, Joshua M.; Patel, Purvish; Rousseaux, Sophie A. L.. Computed Properties of C7H8O2. The article was titled 《Ni-Catalyzed Reductive Cyanation of Aryl Halides and Phenol Derivatives via Transnitrilation》. The information in the text is summarized as follows:

Herein, Ni-catalyzed reductive coupling for the synthesis of benzonitriles from aryl(pseudo)halides and an electrophilic cyanating reagent, 2-methyl-2-Ph malononitrile (MPMN) is reported. MPMN is a bench-stable, carbon-bound electrophilic CN reagent that does not release cyanide under the reaction conditions. A variety of medicinally relevant benzonitriles can be made in good yields. Addition of NaBr to the reaction mixture allows for the use of more challenging aryl electrophiles such as aryl chlorides, tosylates, and triflates. Mechanistic investigations suggest that NaBr plays a role in facilitating oxidative addition with these substrates.
