Preparation of cyclopropanone 2,2,2-trifluoroethoxy hemiacetals via oxyallyl cation
(ARKAT USA, Inc., 2024)
Hemiacetals of cyclopropanone can be isolated and stocked, contrary to their highly reactive parent ketone. However, they are not readily converted to cyclopropanone, which limits their use as its synthetic equivalents. ...
Selective adsorption of sulphur dioxide and hydrogen sulphide by metal–organic frameworks
(Royal Society of Chemistry (RSC), 2023)
The removal of highly toxic gasses such as SO2 and H2S is important in various industrial and environmental applications. Metal organic frameworks (MOFs) are promising candidates for the capture of toxic gases owing to ...
Copper(II) and silver(I) complexes with dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz): the influence of the metal ion on the antimicrobial potential of the complex
(Royal Society of Chemistry (RSC), 2023)
Dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz) was used as a ligand for the synthesis of new copper(II) and silver(I) complexes, [CuCl2(py-2pz)]2 (1), [Cu(CF3SO3)(H2O)(py-2pz)2]CF3SO3·2H2O (2), [Ag(py-2pz)2]PF6 ...
Exploring the supramolecular profile of 5-phenylhydantoins
(Royal Society of Chemistry, 2023)
The present study describes representative examples of supramolecular arrangement of 5-phenylhydantoins achieved through various N–H⋯O hydrogen-bonding patterns. Four derivatives, 5-ethyl-5-(4-methylphenyl)hydantoin (1) ...
Improving the HER Activity and Stability of Pt Nanoparticles by Titanium Oxynitride Support
(American Chemical Society (ACS), 2022)
Water electrolysis powered by renewables is regarded as the feasible route for the production of hydrogen, obtained at the cathode side through electrochemical hydrogen evolution reaction (HER). Herein, we present a rational ...
Synthesis of novel pyridinium based compounds and their possible application in dye-sensitized solar cells
(Elsevier, 2023)
Five novel D-π-A structured pyridinium based compounds, bearing different electron-donating units were synthesized, minutely characterized, and their solvatochromic and electronic properties were investigated. Subsequently, ...
Application of Screen Printed Diamond Electrode, Coupled with “Point-of-Care” Platform, for Nanomolar Quantification of Phytonutrient Pterostilbene in Dietary Supplements: An Experimental Study Supported by Theory
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Herein, a screen–printed diamond electrode (SPDE) coupled with a “point-of-care” platform (30 µL-drop concepts, single-drop-detection approach) was successfully applied for the electrochemical determination of pterostilbene ...
