Hydrolytic removal of the core unit and cross‐linking of their wedges enables dendrimers to be “cored” (see schematic representation). By internalizing the alkenes, the ring‐closing metathesis reaction will “stitch” the dendritic wedges together intramolecularly, even at dendrimer concentrations of 10 −3 M . In contrast, peripheral alkenes react intermolecularly at this concentration.
