Abstract

(β-Oxoiminato)(phosphanyl)palladium complexes have been used as catalysts in Suzuki–Miyaura coupling reactions. In the presence of these palladium complexes, various aryl iodides and bromides were efficiently coupled with phenylboronic acid with extremely high turnover frequencies under mild conditions. Furthermore, the catalyst system was also found to be effective in the reactions of aryl chlorides. This work indicates that these palladium complexes can serve as highly active catalysts in Suzuki–Miyaura reactions.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
