BiOBr nanoplates were successfully attached to hollow NH2-MIL-125(Ti) surface to form Z-format defect heterojunction. In pure water, the optimized oxygen-containing vacancy catalyst reduced CO2 to CO with near 100% se...
Base‐catalyzed Effective C2‐Amidation of Azolium Salts Using Isocyanates under Mild Conditions
Von Wiley-VCH zur Verfügung gestellt
An efficient base-catalyzed hydroarylation of isocyanates with azolium salts was developed, which provided facile access to a diverse family of C2-amidated azolium salts under mild conditions.
An unprecedented base-catalyzed hydroarylation of isocyanates with azolium salts was developed, which follows a simple reaction pathway and provided facile access to diverse C2-amidated azolium salts under mild conditions. Importantly, this methodology can also be applied for the successive C2-amidation of a bisimidazolium salt with two different isocyanates to provide the corresponding unsymmetrically substituted bisamide derivatives. Notably, the obtained amidated salts can also serve as a prominent carbene surrogate for the synthesis of metal-NHC complexes.Zum Volltext
