Synthesis of a Series of Novel Bis-Bidentate Ligands Utilizing 2,6-Diaminotoluene

Padi, Sathish R.K., Jason Cebulski, Brandon Korfel, and Mark Benvenuto

A novel series of bis-bidentate ligands, all incorporating 2,6-diaminotoluene, has been synthesized. All contain heteroatom donor Lewis bases that are nitrogen, oxygen, or sulfur. The stability of this series of ligands as free molecules and as hydrochloride salts will be presented, as will their aqueous and organic solubility. Characterization has been primarily by proton and carbon NMR. This, as well as their metal binding potentials, will be discussed.
