摘要：
Linear polystyrene-stabilized Rh-(III) nanoparticles (PS-Rh((III))NPs) were obtained when an aqueous solution of RhCl3 was stirred at 90 degrees C in the presence of KOH, 4-methylphenylboronic acid, and linear polystyrene, as indicated by X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). PS-Rh-(III) NPs exhibited high catalytic activity for the oxidative coupling of arylboronic acids with alkenes. In contrast, PS-Rh-(0) NPs prepared with NaBH4 had little activity for the same reaction. (C) 2018 Elsevier B.V. All rights reserved.
