New alkene-terminated phosphine dendron-protected palladium nanoparticles (NPs) have been synthesized, and the olefin metathesis polymerization of their Pd NPs led to shell crosslinked Pd NPs without aggregation of the Pd NPs. The introduction of crosslinking at the surface of the protective ligand enhanced the catalytic activity of the Pd NPs for Suzuki– Miyaura couplings.
