Abstract

Abstract: Novel bi-and tridentate imidazole chelate ligands consisting of varying donor sets were prepared using an efficient one-or two-step procedure. Keto-and methylene-bridged bisimidazoles 1, 2 served as versatile starting materials for the introduction of additional donor groups, thus allowing the facile variation of donor sets within a bisimidazole ligand framework.
