A corrosion-resistant conductive structure includes: a substrate, a conductive layer, and a protective layer. The conductive layer is disposed on the substrate and includes a metal, a metal alloy, or a metal oxide. The protective layer overlies the conductive layer and includes a resin and a first component; the first component includes a heterocyclic dizane compound or a derivative thereof. A corrosion-resistant coating composition includes: a resin, a first component, and a solvent. The first component includes a heterocyclic dizane compound or a derivative thereof, wherein the concentration of the first component ranges from 0.01 mg/L to 180 mg/L.
Palladium-Catalyzed C−H Aminations of Anilides with <i>N</i>-Fluorobenzenesulfonimide
The first amide-directed, palladium-catalyzed, intermolecular, highly selective C-H aminations with the non-nitrene-based nitrogen source N-fluorobenzenesulfonimide have been developed. This methodology might provide a new pathway for directed metal-catalyzed aromatic C-H amination.
