Bridged 1-methylbisimidazoles as building blocks for mixed donor bi- and tridentate chelating ligands

Article abstract of DOI:10.1055/s-2001-12351

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.
