Silica-Supported Phosphine Palladium(0) Complex Catalyzed Phenylation of Acid Chlorides and Aryl Iodides by Sodium Tetraphenylborate

Abstract

In the presence of a catalytic amount of silica – supported phosphine palladium(0) complex, sodium tetraphenylborate (NaBPh₄) reacts with acid chlorides under mild conditions to give the corresponding phenyl ketones in 57 – 80% yields; it also reacts with aryl iodides to afford the corresponding biaryls in 75 – 84% yields.
