Catalytic Carbon-Carbon Bond Formation Reactions with Bis(oxazolinyl)phenyl-palladium(Phebox-Pd)Catalysts

摘要

Bis(oxazolinyl)phenyl-palladium(II)(Phebox-Pd)complexes catalyzed various carbon-carbon bond formation reactions such as Heck-Mizoroki reaction,Suzuki-Miyaura reaction and Sonogashira reaction to give the corresponding aryl-substituted products in high yield.In the case of Heck reaction,the reaction of iodobenzene and acrylic acid methyl ester in DMF in the presence of Phebox-PdCl(0.01-5.0 mol%)gave cinnamic ester in high yield.The catalyst was recovered quantitatively as Phebox-Pdl and it was extremely stable under air and water and reusable.
