Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

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

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

open access: yesEcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand

From Olefin Coordination to Rh─N Bond Formation and Oxidative Addition: pH Effects in Rhodium α‐Methyl‐β‐Amidoitaconate Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The coordination of α‐methyl‐β‐amidoitaconate at Rh(I) diphosphine complexes is studied using a combination of high‐field and low‐field flow NMR spectroscopy and X‐ray analysis. In the presence of basic or acidic additives, the formation of neutral Rh(I) or Rh(III) complexes occurs.

Exploring the Anticancer Activity of Ruthenium(II)–Arene and Copper(I) Complexes Bearing N‐Heterocyclic Carbene Ligands Containing Azido, Pyridinium, and Ethisterone‐Derived Triazole Groups

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A versatile library of backbone‐functionalized N‐heterocyclic carbene (NHC) ligands was developed and efficiently converted into Cu(I) and Ru(II) NHC complexes, demonstrating that ligand functionalization strongly modulates anticancer activity, with Cu(I)–NHC species showing potent and selective antiproliferative effects against ovarian and breast ...
