Polyamine Anchored Palladium Catalyst for Suzuki-Miyaura and One-Pot O-Alkylation-Suzuki Reactions
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] .
