Abstract:

A novel set of thiosemicarbazone palladacycles is discussed. The addition of a fluorine atom to the thiosemicarbazone ligand increases not only the solubility of the ligand itself, but also that of the ensuing cyclometallated complexes.

Ligands are synthesized in acidic ethanolic solution, and then reacted with potassium tetrachloropalladate(II), to give the corresponding cyclopalladated compounds bearing a tetranuclear structure.

Characterization will be carried by IR, ¹H NMR and ¹⁹F NMR spectroscopies.

Keywords: thiosemicarbazone; palladium; cyclometallation; fluor; solubility
