摘要:
Thiosemicarbazone-derivatised palladium nanoparticles with average crystallite size 16.2 nm have been prepared and characterized by XRD and SEM. The nanoparticles were found to efficiently catalyze the Suzuki-Miyaura cross-coupling of aryl bromides ( from electron-rich to electron poor) with phenylboronic acid even at room temperature, and they can be recovered and reused.
