| Abstract: | Palladium nanoparticles with the size ranged from 5 nm to 25 nm confirmed by transmission electron microscopy(TEM),generated in situ from the reaction of palladium(II) chloride and stabilized by Gemini quaternary ammonium salt,have been demonstrated to be an ef?cient catalyst for Suzuki car-bon-carbon cross coupling reaction.A variety of aryl bronic acids and aryl halides have been proceed smoothly to afford the corresponding biaryls in high yields by using palladium nanoparticles in the presence of potassi... |
