Abstract Covalent organic frameworks (COFs) have been considered a potentially versatile electrode structure if they are made highly conductive and flexible to stabilize the redox functionality. Although conceptually plausible, COF‐based electrodes rarely satisfied high capacity, cyclability, rate capability thus far. Incorporating thiazole moieties into scaffold, it is able fabricate π‐conjugated crystalline demonstrate fast two‐electron transfer in one step using azo The thiazole‐linked...
A highly efficient one-pot synthesis of 3-azidopiperidines has been achieved by an intramolecular cyclization unsaturated amines that allows for the nucleophilic installation azide moiety. This method unlocks versatile employment functionality in preparation and biological studies piperidine-containing structures. strategy expanded direct incorporation a variety nitrogen nucleophiles, thus it provides rapid modular 3-amino 3-amidopiperidines important pharmaceutical relevance. Particularly...
We herein disclose the Cp*Co(III)(LX)-catalyzed amidative alkyl migration using 2,6-disubstituted phenyl azidoformates. Upon cobalt–nitrenoid insertion toward substituted ortho carbon, an arenium cationic species bearing a quaternary carbon is generated, and subsequent process suggested to occur through unforeseen alkyl-walking mechanism. A quinolinol ligand of cobalt catalyst system proposed facilitate final product-releasing rearomatization by serving as internal base. This new mechanistic...
We disclose herein a Cp*Co(III)(LX)-catalyzed dearomative Diels–Alder dimerization of 2,6-disubstituted phenyl azidoformates. Upon the postulated cobalt-nitrenoid insertion into neighboring ortho-carbon, key intermediate ortho-quinamine was generated for subsequent dimeric cycloaddition process. A series experimental and computational studies suggested that quinolinol ligand cobalt catalyst plays crucial role in alcoholic solvent incorporation o-quinamine moiety, thereby enabling to furnish...
