New ruthenium(II) complexes of 2,2′:6′,2″-terpyridine derivatives as supramolecular building blocks

Eight new heteroleptic ruthenium(II) complexes of 2,2′:6′,2″-terpyridine derivatives are reported and characterized by multinuclear NMR and electrospray mass spectrometry. Complexes featuring pendant aryl bromide or pyridyl groups in the 4′ position of terpyridine are suitable for palladium(0) coupling reactions to form large metallo-supramolecular ligands. Aryl boronic ester derivatives were found to be unstable with respect to hydroxylation.
