The Synthesis of Catechol and 8-Hydroxyquinoline Derivatives with Short Peptide-Type Side Chains: Metal Complex Ligands with Additional Receptor Properties

Abstract

Glycine-N-amide substituted catechol and 8-hydroxy­quinoline ligands were prepared and were used to obtain mixtures of isomers of dicatecholate molybdenum(VI)dioxo and tris-8-hydroxyquinolinate gallium(III) complexes. Upon addition of nitrate to the complex [(5)₂MoO₂]^2- an allosteric binding of the metal as well as of the anion takes place.

Key words

allosteric effects - ligand - amide - metal complex - receptors
