Synthesis of organometallic dendrimers by ligand exchange reactions: reversible bonding of dendrons to a core in transition metal acetylide dendrimers

Abstract

Ligand exchange reactions of chloride ligands on a trinuclear palladium acetylide core with platinum acetylide dendrons having a 4-pyridyl group at a focal point result in the quantitative formation of novel organometallic dendrimers, which easily revert to the core and the dendrons by treatment with Bu₄NCl.
