Synthesis and solution thermodynamic study of rigidified and functionalised EGTA derivatives†
Abstract
The synthesis of a new series of EGTA (ethyleneglycol-bis(2-aminoethylether)-N,N,N′,N′-tetraacetic acid) derivatives incorporating aromatic and functionalized aromatic moieties into the oxoethylenic bridge is described. A solution thermodynamic study was carried out to determine the influence of structural modifications on the coordinating ability towards lanthanide and
