Chelatbildende Enaminoketone II. Synthese von symmetrischen Liganden.

Syntheses of Bis-enaminoketones are described, which are able to form square planar chelates with transition metals. Tetra- and multidentate ligands were prepared from anilinomethylene derivatives of 1,3-dicarbonyl compounds and various diamines. Lipophilic ligands were prepared with respect to potential use as carriers in liquid membrane permeation. Incorporation of the ligands into a polymer (via a spacer group) was performed by radical polymerization. [ABSTRACT FROM AUTHOR]
