Abstract
Three novel multidentate long-chained oligo-α;-aminopyridine ligands, nonapyridyloctaamine (1, npoa), decapyridylnonaamine (2, dpna), and undecapyridyldecaamine (3, upda) were synthesized successfully by tandem Pd-catalyzed cross-coupling aminations. The helical structures of protonated ligand npoa {4, [H 4·npoa](SO 3CF 3) 4} and the related dinuclear complexes 5-10 were synthesized and characterized by X-ray diffractions. © 2004 Elsevier Ltd.
