Nanoparticles Pd-Catalyzed Suzuki and Heck Cross-Coupling Reactions of Arenediazonium Tetrafluoroborate Salts

Abstract

An efficient protocol for the Suzuki and Heck reactions of arenediazonium tetrafluoroborate salts catalyzed by Pd(PPh 3) 4-derived nanoparticles palladium catalyst has been developed. This method is able to prepare a variety of biaryls and aryl olefin under air atmosphere at 25 ℃ in ethanol. In the presence of this catalyst, the cross-coupling reactions of arenediazonium tetrafluoroborate salts with arylboronic acids and olefin proceed smoothly and afford the desired coupling products with good yields, respectively. The catalyst could be recycled 4 times without loss of activity and decrease of yield.
