Synthesis of Planar Five‐Connected Nodal Ligands

Published: April 2009

AbstractThe fiveway junction: The synthesis of ligands with five symmetrically diverging binding sites is described and their assembly into large spherical structures (such as that shown here) investigated.magnified imageSynthetic routes to a penta(4‐pyridyl)cyclopentadienyl ligand are explored. The most successful route uses a palladium‐catalysed pentapyridation of di(tert‐butyl)phosphinoferrocene by using a procedure developed by Hartwig. The same method allows the synthesis of cyclopentadiene ligands substituted with 4‐benzaldehydes or 4‐phenylthiols. The pyridine ligands are formally five‐connected nodes that may be linked by linear coordination metals to give closed spherical complexes of composition [(metal)30(ligand)12] as shown by molecular modelling. Experiment shows that the ligand complexes copper(I) and silver(I) with the expected 1:2.5 stoichiometry, and the 1H NMR spectrum of the resulting product shows the ligands to be equivalent. NMR diffusion and light‐scattering measurements support the formation of a species with a hydrodynamic radius of the order of 15 Å, in agreement with the modelling studies. The resulting complex would be topologically identical to the C60 fullerene structure.
Conformational Flexibility of Tetralactam Macrocycles and Their Intermolecular Hydrogen‐Bonding Patterns in the Solid State

AbstractFlexible rigidity: Tetralactam macrocycles of the Hunter type bear a rigid scaffold (see space‐filling representation), but can still widely adapt to the properties of a guest molecule inside their cavities. X‐ray crystal structures of a series of differently substituted macrocycles reveal a remarkably broad variety of intermolecular hydrogen‐bonding patterns organizing the macrocycles in the crystals in intriguingly different ways.magnified imageDespite their rigid scaffold, tetralactam macrocycles (TLMs) display a remarkable degree of conformational flexibility, as revealed by analysis of the corresponding X‐ray crystal structures. This flexibility is not limited to the rotatability of the TLM amide groups but also applies to the m‐xylene rings, and it thus has a great impact on the overall shape of the macrocycle cavity. The conformational properties of the TLMs give rise to a broad variety of intermolecular hydrogen‐bonding patterns, including infinite ladders, an interesting catemer motif, and short CH⋅⋅⋅OC hydrogen bonds. These results are in accord with previous theoretical calculations, support a structural model proposed earlier for an interpretation of scanning tunneling microscopy images, and substantially contribute to the understanding of the adaptability of macrocyclic scaffolds, which is crucial for guest binding or templated syntheses with TLMs.
