Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

open access: yesChemistry – A European Journal, EarlyView.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Synthesis of 4-Anilino 8-Hydroxy Quinolines [PDF]

open access: yes, 1967
4,7-Dichloro-8-aminoquinoline when treated with nitrous acid afforded 6,9-dichloro triazolo-(4,5,1-ij) quinoline 3-ium hydroxide, which on condensation with anilines gave the 7-chioro 4-anilino 8-hydroxy ...

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

HCo(PMe3)4‐Catalyzed 1,2‐Selective Hydroboration of Quinolines: Access to Isolable N–B and N–H 1,2‐Dihydroquinolines

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Well‐defined cobalt hydride complexes are versatile catalysts. Two key features of HCo(PMe3)4 are that it promotes highly selective 1,2‐hydroboration of quinolines to form N–B‐substituted 1,2‐dihydroquinolines (1,2‐H‐DHQs) under mild conditions, and that its volatile phosphine ligands and high solubility in pentane enable simple purification, allowing ...
