| Indole groups have not been widely used as donor groups in tri-or tetradentate ligands for mononuclear complexes. A deprotonated indole NH group can be used as a negatively charged N-donor. The fused phenyl ring provides steric bulk near the metal center when the N atom is coordinated. We have synthesized a new tridentate ligand with two indole moieties as donor groups as well as its tetradentate analog. The full schemes for the ligand synthesis will be presented. Syntheses of mononuclear metal complexes with these ligands are currently in progress. Metal complexation is being achieved by (1) deprotonation of the two indole-NH groups from either ligand with a strong base followed by (2) addition of a metal source (Cu+, Ni2+, Co2+, Fe2+, or Mn2+). The effects of the bases, metal sources, and the solvents on the reaction behavior will be discussed. The potential uses of the complexes as catalysts will be discussed as well. |
