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.

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.

Product Details of 1194-02-1In 2021 ,《Pyridine-Bridged Polybenzimidazole for Use in High-Temperature PEM Fuel Cells》 appeared in ACS Applied Energy Materials. The author of the article were Harilal; Shukla, Avanish; Ghosh, Prakash Chandra; Jana, Tushar. The article conveys some information:

Although pyridine bridged oxypolybenzimidazole (PyOPBI) membranes are considered to be promising high-temperature proton exchange membrane (HT-PEM) materials that have the potential to overcome many obstacles such as solubility, membrane processability, cost, etc., of the mainstream conventional polybenzimidazole (PBI)-based HT-PEM, the weak structural stability of PyOPBI in concentrated phosphoric acid (PA) and poor dimensional and mech. stability have been the crucial issues restraining the performance. To mitigate these bottlenecks, in this work, we successfully synthesized three types of PyOPBIs with flexible aryl ether backbones and bulky substituents by polycondensation reaction of various aryl diacids and pyridine-bridged tetraamine 2,6-bis(3′,4′-diaminophenyl)-4-phenylpyridine (PyTAB) in Eaton’s reagent followed by casting as HT-PEMs. Three designed bulky substitute containing PyOPBI membranes showed considerably high PA loading capacity (16-22 mol of PA/repeat unit) and proton conductivity (0.04-0.078 S/cm) at 180°C as compared to earlier reported unsubstituted PyOPBI membranes (14 mol of PA/repeat unit and 0.007 S/cm at 180°C). In addition, the obtained membranes showcased good chem., mech., thermal, and long-term conductivity stabilities and outstanding stability in concentrated PA. The pendent groups and the bulkiness of the backbone are believed to be the cause behind better stability and facilitating proton transport that results in higher proton conductivity The single cell made from the membrane electrode assembly of these bulky substituted PyOPBI membranes displayed a peak power d. in the range of 144-240 mW cm-2 under H2/O2 at 160°C, which is considerably higher than that for unsubstituted PyOPBI membrane (90.4 mW cm-2). Overall, the current results provide an effective strategy to explore the benefits of structural modulation of PyOPBI using various structurally divergent diacids to enhance HT-PEM properties and suggest a scalable route for the advancement of PBI-based HT-PEM fuel cells. In the experiment, the researchers used 4-Fluorobenzonitrile(cas: 1194-02-1Product Details of 1194-02-1)

New 1,2,4-oxadiazole-containing trans-cinnamic acids I (R = Ph, 2-MeOC6H4, 3-MeOC6H4, 4-FC6H4, 4-ClC6H4, 4-MeC6H4) were synthesized and evaluated as dual PPAR-α/γ agonists. Using AutoDock Vina, compounds I were identified as potential PPAR α/γ dual agonists comparable to PPAR γ agonist Pioglitazone on the basis of their affinity scores, in-silico toxicity and in-silico ADME properties. These compounds showed better calculated lipophilicity (iLogP), which was found to be from 0.92 to 3.19. Compounds I (R = Ph, 4-FC6H4) were found to be most potent on both PPAR α and γ receptors with EC50 of 0.07 ± 0.0006μM, 0.06 ± 0.0005μM and 0.781 ± 0.008μM, 3.29μM ± 0.03 resp. compared to pioglitazone having EC50 of 32.38 ± 0.2 and 38.03 ± 0.13 for both receptors. The in-vivo evaluation found to reduce the plasma glucose level and total cholesterol level significantly in diabetic rats compared to pioglitazone at 5 mg/kg/day dose for 7 days of treatment. Thus, trans-cinnamic acids I can be further developed as oral therapeutic agents for diabetic interventions as PPAR α/γ dual agonists.

The development of a Stille coupling protocol that is operable under moderate conditions without using a base is highly required for the synthetic organic chem. community, which requires an efficient nanocatalyst. In this respect, addressed herein is a facile one-pot synthesis of mesoporous graphitic carbon nitride (mpg-CN) supported Pd NPs, denoted as mpg-CN/Pd hereafter, and investigation of their catalytic activity in Stille cross-coupling reactions for the first time. It has been demonstrated that mpg-CN nanosheets can serve as not only a support material but also a stabilizer for the generation of 4.5 nm Pd NPs. The ecofriendly generated heterogeneous nanocatalyst was characterized by TEM, XRD, XPS, BET surface area and ICP-MS anal. The mpg-CN/Pd nanocatalysts showed high activity in the Stille coupling reaction of a variety of electron-deficient and electron-rich aryl iodides/bromides and two different organostannanes with a wide substrate scope to afford the corresponding biaryls without using any bases and addnl. ligands under relatively mild conditions.
