Kammer, Lisa Marie; Badir, Shorouk O.; Hu, Ren-Ming; Molander, Gary A. published their research in Chemical Science in 2021. The article was titled 《Photoactive electron donor-acceptor complex platform for Ni-mediated C(sp3)-C(sp2) bond formation》.HPLC of Formula: 623-00-7 The article contains the following contents:

A dual photochem./nickel-mediated decarboxylative strategy for the assembly of C(sp3)-C(sp2) linkages was disclosed. Under light irradiation at 390 nm, com. available and inexpensive Hantzsch ester (HE) functions as a potent organic photoreductant to deliver catalytically active Ni(0) species through single-electron transfer (SET) manifolds. As part of its dual role, the Hantzsch ester effects a decarboxylative-based radical generation through electron donor-acceptor (EDA) complex activation. This homogeneous, net-reductive platform bypasses the need for exogenous photocatalysts, stoichiometric metal reductants, and additives. Under this cross-electrophile paradigm, the coupling of diverse C(sp3)-centered radical architectures (including primary, secondary, stabilized benzylic, α-oxy, and α-amino systems) with (hetero)aryl bromides was accomplished. The protocol proceeded under mild reaction conditions in the presence of sensitive functional groups and pharmaceutically relevant cores. In addition to this study using 4-Bromobenzonitrile, there are many other studies that have used 4-Bromobenzonitrile(cas: 623-00-7HPLC of Formula: 623-00-7) was used in this study.

Buravchenko, Galina I.; Scherbakov, Alexander M.; Dezhenkova, Lyubov G.; Monzote, Lianet; Shchekotikhin, Andrey E. published their research in RSC Advances in 2021. The article was titled 《Synthesis of 7-amino-6-halogeno-3-phenylquinoxaline-2-carbonitrile 1,4-dioxides: a way forward for targeting hypoxia and drug resistance of cancer cells》.SDS of cas: 614-16-4 The article contains the following contents:

To establish a new approach for the synthesis of quinoxaline 1,4-dioxides as hypoxia-selective cytotoxic agents, an original multi-step preparation of derivatives possessing the diamine moiety at position 7 was evaluated. Herein, we present the synthesis of a series of novel 7-amino-6-halogeno-3-phenylquinoxaline-2-carbonitrile 1,4-dioxides 13a-h, 14a,b,g based on the regioselective Beirut reaction. Comparison of antitumor properties of derivatives possessing the diamine moiety at position 7 with structurally close congeners possessing the corresponding amino groups at position 6 revealed key differences in the cytotoxicity profiles and HIF-1α inhibition. All the synthesized 7-amino-6-halogeno derivatives 13a-h, 14a,b,g demonstrated significant cytotoxic activities against breast cancer cell lines (MCF7, MDA-MB-231) in normoxia and hypoxia with IC50 values ranging from 0.1 to 7.6 μM. Most of these novel derivatives can circumvent the multidrug resistance of tumor cells caused by P-glycoprotein over expression. The lead compounds 13a, 14a and 14b can suppress the expression of HIF-1α at low micromolar concentrations and induce apoptosis in breast cancer MCF7 cells. In addition, compound 14b effectively inhibits BCL2 and ERα expression in MCF7 cells. The current research opens a new direction for targeting hypoxia and drug resistance of cancer cells.3-Oxo-3-phenylpropanenitrile(cas: 614-16-4SDS of cas: 614-16-4) was used in this study.

Guo, Xiangyang; Liu, Lifang; Xiao, Yu; Mehmood, Rashid; Xiao, Yejun; Qi, Yu; Zhang, Fuxiang published their research in Inorganic Chemistry in 2021. The article was titled 《Water-Stable Cobalt-Based MOF for Water Oxidation in Neutral Aqueous Solution: A Case of Mimicking the Photosystem II》.Related Products of 1194-02-1 The article contains the following contents:

Inspired by the highly efficient H2O oxidation of Mn4CaO5 in natural photosynthesis, development of novel artificial H2O oxidation catalysts (WOCs) with structure and function mimicked has inspired extensive interests. A novel 3-dimensional Co-based MOF (GXY-L8-Co) was synthesized for promising artificial H2O oxidation by employing the Co4O4 quasi-cubane motifs with a similar structure as the Mn4CaO5 as the core. The GXY-L8-Co not only shows good chem. stability in common organic solvents or H2O for up to 10 days but also exhibits oxygen evolution performance. The uniform distribution of Co4O4 catalytic active sites confined in the MOF framework should be responsible for the good robustness and catalytic performance. A Co4O4 quasi-cubane motif was synthesized in a Co-MOF with a similar structure to that of the natural oxygen-evolving complex Mn4CaO5 in PSII.

Application of 1194-02-1In 2019 ,《Extending the Chemistry of Hexamethylenetetramine in Ruthenium-Catalyzed Amine Oxidation》 was published in Organometallics. The article was written by Kannan, Muthukumar; Muthaiah, Senthilkumar. The article contains the following contents:

A very efficient, highly atom economical, and environmentally benign oxidation of primary and secondary amines using an in situ catalyst system generated from com. available Ru(II) benzene dichloride dimer and hexamethylenetetramine was demonstrated. Mechanistic studies revealed that hexamethylenetetramine acted as a source of hydride to generate the active Ru hydride catalyst and amine oxidation involves a dehydrogenative pathway. In comparison to reported catalyst systems for the dehydrogenative oxidation of amines, this synthetic protocol makes use of a simple Ru precursor and a cheaper additive; it is very selective, leading to the exclusive formation of nitrile/imine compounds Further, it releases H as the only side product, suggesting the potential application of the developed catalyst system in H storage.
