A Facile Synthetic Route to a Third-Generation Dendrimer with Generation-Specific Functional Aryl Bromides

The synthesis of three third-generation dendrimers that selectively carry one aryl bromide functional group in the first, second, or third generation, respectively, is described. These functions, regardless of their location, can be chemically modified by Suzuki cross-coupling chemistry with p-tert-butylbenzene boronic ester.
