The Catellani reaction provides an efficient synthetic approach to polyfunctionalized arenes. However, the selective -arylating reagents employed in these reactions have been strictly limited to activated bromoarenes. As demonstrated in this work, aryl diazonium salts bearing both electron-donating and electron-withdrawing substituents, after in situ transformations with KI into the corresponding iodoarenes, were efficient arylating reagents for Catellani type -arylation approaches.

Redox-active organic-inorganic hybrid electrode materials are promising candidates for eco-friendly, high-energy-density supercapacitors. The synergy between organic and inorganic components in energy storage devices has attracted considerable interest due to their complementary attributes, including flexibility, long-term stability, and high conductivity. This study presents an innovative approach for synthesizing an organic-inorganic active electrode material by grafting diazonium salts of 8-aminoquinoline (8-AQ-N ) onto CuFeO nanoparticle (NP) surfaces.

Photocatalytic nitrogen reduction offers a sustainable approach to ammonia production. Here, we develop covalently functionalized 2D fullerene (C) networks through aryl diazonium chemistry, as verified by neutron scattering, spectroscopic analysis, and atomic force microscopy (AFM). The functionalized 2D fullerenes (e.

Herein, we report a straightforward methodology for direct deaminative cyanation of anilines via aryl diazonium salts as fleeting intermediates. The approach leverages the kinetic stability of nitrate and copper cyanide, iron's ability to facilitate nitrate reduction, and appropriate relative rates to ensure the product-forming kinetic reaction pathway despite several thermodynamically favored, undesired reactions. We present insight into the previously unappreciated nitrate reduction mechanism by simple sulfur-based reductants, such as SO.

Surface-capping molecular ligands are an integral part of virtually all colloidal inorganic nanoparticles that are chemically synthesized. The rational design of nanoparticle-adsorbate hybrid materials with specifically targeted properties and functionalities relies crucially on our understanding of ligand chemistry at the nanoparticle surfaces. Organic ligand molecules can interact covalently with metal surfaces through chemisorption using a variety of surface-binding moieties, most commonly thiol groups, to form self-assembled monolayers of monomeric adsorbates when reaching the saturated surface-coverage.

The Sandmeyer reaction is a key method for synthesizing aryl halides but often requires complex procedures and large solvent volumes. This study introduces a mechanoredox system using ball milling to activate piezoelectric BaTiO, enabling solvent-minimized, metal-catalyst-free halogenation of aryl diazonium salts under air. The method features a broad substrate scope, scalability, and recyclable piezoelectric materials without significant activity loss.
