Abstract: | Syntheses of chelating enaminoketones for a potential use in enrichment or recovery of metals from their aqueous solutions are described. Tridentate ligands were prepared either from aromatic amines, triethoxymethane and cyclic 1,3-dicarbonyl compounds in a one-step synthesis, or from the anilinomethylene compounds obtained by this approach and aliphatic amines. Polymerizable ligands have also been synthesized by reaction with (meth)acryloyl chloride and copolymerized with styrene to yield a chelating polymer. |
