Popis:	Linear polystyrene-stabilized PdO nanoparticles (PS-PdONPs) exhibited high catalytic activity for fluoride-free Hiyama coupling reaction of aryltrimethoxysilanes with a variety of bromoarenes under air in water. In contrast, no desired coupling product was obtained from the Hiyama coupling reaction using linear polystyrene-stabilized Pd nanoparticles (PS-PdNPs) as a catalyst. The different reactivities of PdONPs and PdNPs will be discussed.
