Özet

The synthesis of some new precoursers that contain substituted benzo units and their use in the preparation of azama-crocyclic diester compounds are reported. These precoursers and ligands were characterized by Elemental analysis, H-1 and C-13 NMR spectroscopy, and IR spectroscopy. The complexation constants Ke and DeltaGdegrees values for the diesters with several transition metal cations (Ag+, Zn2+ and Cu2+) in a dioxan-water system using a conductometric method at 25degreesC are also reported.
