Abstract

Three palladium complexes derived from diphenyl-2-pyridylphosphine (PPh2Py) were investigated for their utility as catalysts for the Suzuki-Miyaura reactions of aryl halides in environment friendly solvents such as water, alcohols etc. Good-to-excellent yields of coupling products were achieved with a wide range of aryl halides under mild reaction conditions.
