Synthesis, physico-chemical and iron(III)-chelating properties of novel hexadentate 3-hydroxy-2(1 H)pyridinone ligands

Synthesis of hexadentate ligands via the in situ formation of 1-hydroxy benzotriazolyl active ester in the presence of 2-(1 H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate, TBTU as a coupling agent is described. The pKa values and distribution coefficient values (1-octanol/water) o...

Description
Summary:Synthesis of hexadentate ligands via the in situ formation of 1-hydroxy benzotriazolyl active ester in the presence of 2-(1 H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate, TBTU as a coupling agent is described. The pKa values and distribution coefficient values (1-octanol/water) of the ligands and the stability constants of their iron(III) complexes are reported. Graphic
