Abstract

original image

Small and cool: The mechanism of formation of amine-capped Pd nanoparticles from [Pd(acac)2] (acac=acetylacetonate) is elucidated, and shown to involve Pd–amido and Pd–hydride intermediates. The addition of a Lewis base results in a significant reduction in the temperature at which highly monodisperse nanoparticles are isolated.
