A new building block is constructed with one pyridine and two kinetically inert complexed Pd(II) ions, for the controlled assembly of metallodendrimers following either a convergent or a divergent route. The double pincer ligand 8 was cyclopalladated with Pd[CH3CN](4)(BF4)(2) and subsequently converted into the neutral bis-palladium chloride complex 3. The pyridine moiety of 3, that is covalently attached to the spacer bridging the two pincer complexes, coordinates to activated palladium centers. Via a combination of pyridine(3) and cyano-based (2) building blocks, dendrons up to generation three were assembled and characterized with H-1 NMR and FT-W spectroscopy and MALDI-TOF mass spectrometry. These dendrons can coordinate through a cyano Ligand to an activated nucleus 1 forming convergently assembled metallodendrimers. Alternatively, building blacks 3 were used in the divergent assembly of more stable metallodendrimers, because of the stronger coordination of pyridine compared to cyano ligands. The formation of metallodendrimers is evidenced by IR and H-1 NMR spectroscopy and electro spray and MALDI-TOF mass spectrometry.
