Phosphorescent Iridium Hydrazinonicotinic Acid (HYNIC) Complexes That Bind to Prostate Specific Membrane Antigen: Potential Photodynamic Therapy of Prostate Cancer

open access: yesChemistry – A European Journal, EarlyView.
A phosphorescent iridium(III) complex has been prepared with a 6‐hydrazinonicotinic acid (HYNIC) ligand tethered to a lysine‐ureido‐glutamatic acid pharmacophore, which binds to an enzyme, called prostate‐specific membrane antigen (PSMA), which is overexpressed in prostate cancer.

Lewis‐Acidic Properties and Catalytic Behavior of Hydroboration‐ and Diolysis‐Derived NHC‐Stabilized Borenium Cations

open access: yesChemistry – A European Journal, EarlyView.
A series of thirteen (N‐heterocyclic carbene) NHC‐stabilized borenium cations is synthesized from NHC→BH3 complexes via hydroboration and condensation with diols. The novel compounds are fully characterized. Eight crystal structures are presented. Kinetic and NMR data show how the structural features translate to catalytic activity in hydrosilylation ...

Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...

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.

Recent Advances in Photocatalytic Urea Synthesis via C−N Coupling From C/N‐Containing Species: A Mini Review

open access: yesEcoEnergy, EarlyView.
This review systematically compares photocatalytic urea synthesis from various C (CO2, CO, CH3OH) and N (N2, NH3, NO3−) sources. It highlights C–N coupling mechanisms, key challenges, and future directions, offering a framework to guide rational catalyst design for sustainable, solar‐driven urea production.

Interfacial and Ligand Dual Engineering Toward Energy‐Saving Hydrogen Production Coupled with Sulfion Degradation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...

Recycling Ni‐Rich NCM Cathode Materials From Spent Li‐Ion Batteries as Efficient Electrocatalyst for Urea Oxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mounting battery waste demands sustainable solutions. We recycle spent NCM cathodes into high‐performance urea oxidation catalysts, enabling sustainable hydrogen production and simultaneous urea waste treatment. The burgeoning electric vehicle industry has intensified the demand for high‐energy Ni‐Co‐Mn (NCM) cathodes, yet their end‐of‐life management ...
