Polyamine Anchored Palladium Catalyst for Suzuki–Miyaura and One-Pot O-Alkylation-Suzuki Reactions
摘要:
Polymer anchored amine-palladium complexes were screened as catalysts for Suzuki-Miyaura coupling reactions of aryl halides. The robust, recyclable catalyst was effective in this reaction of aryl bromides and iodides. Aryl bromide was found to undergo selective Suzuki-Miyaura reaction with phenyl boronic acid, even in presence of styrene. The catalyst system was further employed for one-pot O-alkylation-Suzuki reaction to prepare alkoxy biaryl systems in good conversions.[GRAPHICS].
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.
